Definitions
- the present disclosure relates to wearable electronic devices for measuring biological signals.
- Electronic devices may carry out various functions in an integrated manner. For example, smartphones or other portable terminals are advancing to allow users more convenience with better performance. Wearable electronic devices recently developed are a sort of electronic devices with shapes such as wristwatches, headsets, or glasses that may be put on user's body. As such, electronic devices nowadays go beyond their own unique functionalities and converge with other portable devices.
- Sensors of an electronic device may gather information relating to the electronic device, the exterior of the electronic device, or information regarding the user.
- steady measurement of biological signals is critical in a check-up on the user's physical condition.
- the demand for technology that may monitor the user's condition during a workout or diet session is prompting the development of electronic devices equipped with the functionality of checking the user's heart rate.
- a normal resting heart rate refers to a beat count per minute measured while the user lies on the bed. Taking an average of values measured during the same time duration consecutively five or more days as a resting heart rate reduces errors in measurement. However, it is tough for the user to measure their heart rate in the same time duration right before they get up. Five to ten minutes of relaxation prior to measurement of the heart rate using the electronic device also results in a more accurate measurement. Further, this can be quite inconvenient for many users.
- Consecutively check the user's heart rate 24 hours using an electronic device to address such issues results in significant battery consumption.
- the foregoing also fails to distinguish the user's resting heart rate from those measured for the period. Accordingly, the foregoing is not a suitable idea for portable electronic devices.
- a method for automatically measuring a user's biological signal depending on the user's condition in a wearable electronic device and a wearable electronic device for the same are provided.
- a method for detecting a user's resting state to measure a biological signal corresponding to the resting state without the need of remaining still for the measurement and a wearable electronic device for the same.
- a method for reducing power consumption by activating a sensor for measuring a biological signal when the user is determined to be in a resting state based on the detection of a movement of an electronic device put on the user and a wearable electronic device for the same.
- a wearable electronic device comprising: a first sensor configured to sense a movement of the electronic device; a second sensor configured to sense a biological signal for a user wearing the electronic device; and a processor configured to compute a movement value of the electronic device using the first sensor, to detect a resting state when the movement value lasts within a predetermined first threshold range during a first time period, and to configure biological information of the user based on a biological signal measured after detection of the resting state.
- a method for measuring biological information using a wearable electronic device comprises: sensing a movement of the electronic device; computing a movement value of the electronic device using the sensed movement and detecting a resting state when the movement value is within a predetermined first threshold range during a first time period; and configuring biological information of a user wearing the electronic device based on a biological signal for the user measured after detection of the resting state.

- the horizontal axis (X) is a time axis
- the vertical axis (Y) is an axis indicating movement strengths.
- the “axis indicating movement strengths” refers to a variation according to a direction of a force. For example, it may be considered that when the direction of the force is a plus (+) direction, an acceleration acts in a plus (+) direction of one of, at least, the x, y, and z axes of the acceleration sensor, and an acceleration reacts in a minus ( ⁇ ) direction. As shown in FIG.
- the third threshold may be a reference value to determine whether the state is a moving state that arises in a daily routine
- the fourth threshold may be a reference value to determine whether the state is a walking state
- the fifth threshold may be a reference value to determine whether the state is a running state or engaging in strenuous exercise.
- the sensor to measure a heart rate may be activated at the time 1020 that the predetermined time has elapsed. As such, since the sensor module is activated only when required, battery consumption is reduced.
- the profile may mean that the user has engaged in more strenuous activity compared with the profile where the movement strength during the second time period is within the second threshold (e.g., Level2) range. Accordingly, time period D1 should be longer for if the time period D4 during which movement exceeded the fourth threshold (Level4) was long. Accordingly, according to an embodiment of the present disclosure, the minimum heart rate recover time as required before activating the sensor to measure a heart rate may be adjusted depending on the degree of a previous movement.
- FIG. 10A represents movement strengths, specifically, variations in acceleration
- the degree of a movement may also be recognized in a way as shown in FIG. 10B .
- the waveform near “0” denotes the case where the acceleration is 0, and this may occur since the waveform fluctuating between a positive value and a negative value is accelerated in the plus (+) direction by the law of action-reaction, and when put on a halt, it is accelerated in the minus ( ⁇ ) direction by the same law.
- FIG. 10B shows magnitudes through x, y, and z values of the acceleration sensor that are shown to be larger than 0 on the graph, and such values may denote impulses.
- the impulses may be calculated by the following Equation 1.

- whether the movement strength is the second threshold or more during the second time period before the first time period may be determined in operation 1115 .
- the first time period may be adjusted considering the time required for the cardiac function to recover in operation 1117 .
- the adjusted first time period may be rendered to be longer than the previous first time period. In other words, time period D1 is made longer.
- ‘A’ denotes that operation 1125 of FIG. 11A is associated with operation 1130 of FIG. 11B
- ‘B’ denotes that operation 1100 of FIG. 11A is associated with operation 1140 of FIG. 11B .
- the electronic device 101 may determine whether the movement strength during the third time period (D3) after the first time period is less than the first threshold (Level1) in operation 1130 . For example, when the user does not move with the electronic device 101 on during the first time period or does not wear the electronic device 101 so that there is no movement of the electronic device 101 , the electronic device 101 may determine that the moment is a resting time to measure a heart rate in the resting state.
- the movement strength during the third time period may maintain less than the first threshold. Whether the electronic device 101 is worn may be determined in operation 1135 to determine whether no movement occurs since the user does not actually wear the electronic device 101 . When the movement strength during the third time period is less than the first threshold, it may be determined in operation 1135 whether the electronic device 101 is worn in the same manner as operations 815 and 820 of FIG. 8 . Unless the electronic device 101 is determined to be worn in operation 1140 , the process may be terminated.

- the difference between the time when the user enters the resting state based on the sensing data to measure a physical movement and the time when the user actually enters the resting state based on a heart rate may be used to determine the user's heart condition and whether there is a danger of sudden cardiac death. For example, when the user with a disease history, such as heart disease or cardiovascular disease enters the resting state but his heart rate is down to the resting state with a predetermined time or more of delay, such information may be useful to calculate the probability of the user's sudden cardiac death.
- a disease history such as heart disease or cardiovascular disease enters the resting state but his heart rate is down to the resting state with a predetermined time or more of delay

- quantized heart rate variation-based calorie consumption formulas may apply depending on the state and type of the exercise, and when the user is determined to be in sleep, a calorie consumption formula optimized for a sleep state may apply to increase the accuracy of calculation of calorie consumption.

Description
- This is a Continuation application of U.S. patent application Ser. No. 14/974,708 filed on Dec. 18, 2015 which claims the benefit under 35 U.S.C. §119(a) of a Korean patent application filed in the Korean Intellectual Property Office on Feb. 27, 2015 and assigned Serial No. 10-2015-0028418, the entire disclosure of which is incorporated herein by reference.
- The present disclosure relates to wearable electronic devices for measuring biological signals.
- Electronic devices may carry out various functions in an integrated manner. For example, smartphones or other portable terminals are advancing to allow users more convenience with better performance. Wearable electronic devices recently developed are a sort of electronic devices with shapes such as wristwatches, headsets, or glasses that may be put on user's body. As such, electronic devices nowadays go beyond their own unique functionalities and converge with other portable devices.
- More attention is directed to health and leads to vigorous research efforts in electronic device-based healthcare applications. Sensors of an electronic device may gather information relating to the electronic device, the exterior of the electronic device, or information regarding the user. Among others, steady measurement of biological signals is critical in a check-up on the user's physical condition. The demand for technology that may monitor the user's condition during a workout or diet session is prompting the development of electronic devices equipped with the functionality of checking the user's heart rate.
- A normal resting heart rate refers to a beat count per minute measured while the user lies on the bed. Taking an average of values measured during the same time duration consecutively five or more days as a resting heart rate reduces errors in measurement. However, it is tough for the user to measure their heart rate in the same time duration right before they get up. Five to ten minutes of relaxation prior to measurement of the heart rate using the electronic device also results in a more accurate measurement. Further, this can be quite inconvenient for many users.
- Consecutively check the user's heart rate 24 hours using an electronic device to address such issues results in significant battery consumption. The foregoing also fails to distinguish the user's resting heart rate from those measured for the period. Accordingly, the foregoing is not a suitable idea for portable electronic devices.
- The above information is presented as background information only to assist with an understanding of the present disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the present disclosure.

- According to an embodiment of the present disclosure, there are a method for detecting a user's resting state to measure a biological signal corresponding to the resting state without the need of remaining still for the measurement and a wearable electronic device for the same.
- According to an embodiment of the present disclosure, there is a method for reducing power consumption by activating a sensor for measuring a biological signal when the user is determined to be in a resting state based on the detection of a movement of an electronic device put on the user and a wearable electronic device for the same.
- According to an embodiment of the present disclosure, there is a wearable electronic device, comprising: a first sensor configured to sense a movement of the electronic device; a second sensor configured to sense a biological signal for a user wearing the electronic device; and a processor configured to compute a movement value of the electronic device using the first sensor, to detect a resting state when the movement value lasts within a predetermined first threshold range during a first time period, and to configure biological information of the user based on a biological signal measured after detection of the resting state.
- According to an embodiment of the present disclosure, a method for measuring biological information using a wearable electronic device, comprises: sensing a movement of the electronic device; computing a movement value of the electronic device using the sensed movement and detecting a resting state when the movement value is within a predetermined first threshold range during a first time period; and configuring biological information of a user wearing the electronic device based on a biological signal for the user measured after detection of the resting state.

Theprocessor 120 may perform control on at least one of the other components of theelectronic device 101, and/or perform an operation or data processing relating to communication. Theprocessor 120 may receive a command from other component (e.g., thememory 130, the input/output interface 140, thedisplay 150, thecommunication interface 160, or the sensor module 170) through, e.g., thebus 110, may interpret the received command, and may execute computation or data processing according to the interpreted command. - The
processor 120 may be denoted a controller, or theprocessor 120 may include a controller as part thereof. - According to an embodiment of the present disclosure, the
processor 120 may perform the operation of sensing a movement of the electronic device 101 (for example, in conjunction with the sensor module 170), the operation of computing a movement value of the electronic device using the sensed movement to determine a resting time when the movement value is maintained within a predetermined first threshold range during a first time interval, and the operation of configuring bio information of a user wearing the electronic device based on a biological signal for the user measured after the resting time. - Specifically, the
processor 120 may determine whether theelectronic device 101 is worn based on data sensed from thesensor module 170, and when theelectronic device 101 is worn, may compute movement strengths of theelectronic device 101 to determine a variation in movement strength and to determine whether the variation in movement strength is maintained for a predetermined time within a predetermined threshold range. When the variation in movement strength is maintained for the predetermined time within the predetermined threshold range is considered to be in a resting state where there is little or no movement of the user, and a bio sensor for measuring a biological signal may be activated to measure a biological signal in the resting state. - According to an embodiment of the present disclosure, the

Besides, other biological signals, such as the user's blood pressure, blood flow, respiration rate, oxygen saturation, cardiorespiratory sound, or blood sugar, may be measured to determine the user's state in the resting state. - As described above, at the time of being determined to be in the resting state based on the detection of a movement of the
electronic device 101 put on the user, the bio sensor may be activated to measure a heart rate. Thus, power consumption of theelectronic device 101 may be minimized. According to an embodiment of the present disclosure, since the bio sensor is activated considering a previous movement state even when it is determined to be in the resting state, a more accurate result of measurement of a heart rate corresponding to the resting state may be obtained. - The
memory 130 may store a command or data received from other component (e.g., the input/output interface 140, thedisplay 150, thecommunication interface 160, or the sensor module 170) or a command or data generated by theprocessor 120 or other component. Thememory 130 may retain programming modules including, e.g., akernel 131,middleware 132, an application programming interface (API) 133, or anapplication 134.

Thememory 130 may further store sensing data (e.g., speed, acceleration, or traveling direction of the electronic device 101) measured by an acceleration sensor or gyro sensor included in thesensor module 170. Thememory 130 may further store sensor values to analyze the speed, acceleration, or traveling direction of theelectronic device 101 to determine the user's current moving state or movement (e.g., walking, jogging, or sleeping). - The
memory 130 may previously retain data to determine whether theelectronic device 101 is worn based on the sensing data. Further, thememory 130 may previously retain data to determine a state where the user comes to rest and is in a stable condition while the user does their daily routine with theelectronic device 101 on them. Further, bio sensor values measured in every resting state where the variation in movement strength is maintained for a predetermined time within a predetermined threshold range may be recorded in thememory 130.

Further, upon storing a bio sensor value, information collected under the control of theprocessor 120 may be stored as well. For example, the place corresponding to the location information on theelectronic device 101, time of the measurement, or use history of the application on theelectronic device 101 may be stored, mapped with bio information configured based on the bio sensor values. - The
kernel 131 may control or manage system resources (e.g., thebus 110, theprocessor 120, or the memory 130) used to execute the operation or function implemented in the other programming modules, e.g., themiddleware 132, theAPI 133 or theapplication 134. Thekernel 131 may provide an interface that allows themiddleware 132, theAPI 133, or theapplication 134 to access the individual components of theelectronic device 101 to control or manage the same. - The
middleware 132 may function as a relay to allow theAPI 133 or theapplication 134 to communicate data with thekernel 131. A plurality ofapplications 134 may be provided. Themiddleware 132 may perform control in response to work requests received from theapplications 134, e.g., by allocating the priority of using the system resources of the electronic device 101 (e.g., thebus 110, theprocessor 120, or the memory 130) to at least one of the plurality ofapplications 134 in relation to the work requests. - The
API 133 is an interface allowing theapplication 134 to control functions provided from thekernel 131 or themiddleware 132. For example, theAPI 133 may include at least one interface or function (e.g., a command) for filing control, window control, image processing or text control. - According to an embodiment of the present disclosure, there may be provided a plurality of
applications 134 including a short message service (SMS)/multimedia messaging service (MMS) application, an email application, a calendar application, an alarm application, a health care application (e.g., an application for monitoring a state of measuring a heart rate or an application for measuring calorie consumption based on the heart rate), or an environmental information application (e.g., an application providing atmospheric pressure, moisture, or temperature information). Further, theapplication 134 may be an application related to information exchange between theelectronic device 101 and an external electronic device (e.g.,electronic device 103 or 104). Examples of the information exchange-related application may include, but is not limited to, a notification relay application for transferring specific information to the external electronic device, or a device management application for managing the external electronic device. - For example, in the case of the health care application, the user may execute the health care application to access the

FIG. 5 illustrates an example in which thesensor module 400 is disposed at the center of the rear surface of the substantiallyflat body housing 311 of the electronic device, thesensor module 400 may alternatively be disposed on an edge of the rear surface or may be disposed at any other positions where thesensor module 400 may come in contact with the user's body. Further, as shown inFIG. 6 , thebody housing 311 may have a predetermined curvature suited for the shape of the user's body, e.g., the thickness or curvature of the wrist, so as to come in snug contact with the user's skin. Thecontact members 340, e.g., recharging terminals, may be arranged adjacent to thesensor module 400. -
FIG. 7 is a perspective view illustrating a glasses-type electronic device where a sensor module is positioned according to an embodiment of the present disclosure. - Referring to
FIG. 7 , theelectronic device 700 may be implemented as a display device wearable on the user's body, e.g., face or head. A see-through display unit may be positioned in a region adjacent to the user's head (e.g., an eye), and a speaker (not shown) may be positioned in a region adjacent to the user's ear to provide the user with visual information and auditory information. Theelectronic device 700 may include a glasses-type display device or a helmet-type display device. Theelectronic device 700 may include a monocular-type display device with a single display unit for displaying content or a binocular-type display unit with a plurality of display units. - As shown in
FIG. 7 , asensor module 710 may be disposed on a portion of theelectronic device 700 snugly contacting the user's body (e.g., sides of the head). AlthoughFIG. 7 illustrates an example in which the proximity sensor to sense whether theelectronic device 700 is worn and the bio sensor to measure a biological signal are provided together in a region of theelectronic device 700, the proximity sensor and the bio sensor may be arranged separately from each other. Accordingly, the position of thesensor module 710, e.g., the proximity sensor or the bio sensor, may be changed corresponding to the performance or structure of theelectronic device 700 in order to measure a biological signal while sensing whether theelectronic device 700 is worn. -
FIG. 8 is a flowchart illustrating an operation for determining a state in which an electronic device is worn according to an embodiment of the present disclosure. Theelectronic device 101 monitors the resting state when the device is worn and when the movement strength is less than a threshold for at least a predetermined time. When the device is worn, biological signals can be measured. When the movement strength is less than the threshold for at least the predetermined time, the user is deemed to be at rest. - Referring to
FIG. 8 , theelectronic device 101 may determine through thesensor module 170 whether a movement occurs inoperation 800. When a movement occurs, a variation in movement strength of theelectronic device 101 may be determined inoperation 805. Here, the variation in movement strength may represent a variation history between the current degree of movement and the degree of movement that occurred a predetermined time before the current movement. - According to an embodiment of the present disclosure, the
electronic device 101 may compute a movement value according to the movement of theelectronic device 101 using the acceleration sensor and may compute the variation in movement strength of theelectronic device 101 using the computed movement value. According to an embodiment of the present disclosure, theelectronic device 101 may compute variations in movement strength in predetermined time units, e.g., one second, five seconds, or other various time units. Accordingly, the variation in movement strength may be computed at a predetermined period, e.g., ten times per second, and the period of computing the variation in movement strength may be changed. - The
electronic device 101 may determine the variation in movement strength to determine whether the pattern of the variation in movement strength is a predetermined pattern inoperation 810. According to an embodiment of the present disclosure, the predetermined pattern may be a pattern in which the movement strength is reduced. For example, when the user holds up theelectronic device 101 on the table and puts it on his wrist, the movement strength when theelectronic device 101 is held up may be larger than the movement strength when theelectronic device 101 is put on. Further, the movement strength when putting on theelectronic device 101 may be small as compared to holding up theelectronic device 101 because of band adjustment or other manipulations to make theelectronic device 101 snug with the wrist. - If during
operation 810, the movement strength variation does not follow the predetermined pattern, the process is terminated. - As such, when the movement strength is reduced, the
electronic device 101 may determine whether theelectronic device 101 is worn inoperation 815. That is, when receiving movement measurements by thesensor module 170 that are consistent with the user wearing theelectronic device 101, it may be determined that the user has actually worn theelectronic device 101. To that end, theelectronic device 101 may determine whether theelectronic device 101 is worn using thesensor module 170. - According to another embodiment of the present disclosure, the
electronic device 101 may determine whether theelectronic device 101 is worn using a proximity sensor. Upon using a proximity sensor provided on the rear surface of theelectronic device 101, the proximity sensor on the rear surface of theelectronic device 101 may determine whether a portion of the user's body has approached the proximity sensor. Whether theelectronic device 101 is worn can be determined in the foregoing manner. - According to another embodiment of the present disclosure, the
electronic device 101 may determine whether theelectronic device 101 is worn using a GSR sensor. The GSR sensor may determine whether a portion of the user's body has contacted or approached the GSR sensor according to an electric conductance measured by the GSR sensor. Based on the electrical conductance, theelectronic device 101 can determine whether it is worn. - According to an embodiment of the present disclosure, the
electronic device 101 may determine whether theelectronic device 101 is worn using a temperature sensor. When using the temperature sensor, theelectronic device 101 may determine a portion of the user's body has approached the temperature sensor according to temperature measurements. Theelectronic device 101 can use the temperature measurements to determine whether it is worn. According to an embodiment of the present disclosure, theelectronic device 101 may also determine which portion of the body, theelectronic device 101 is being worn, e.g., the user's wrist, head, arm, ankle, or face. - If during
operation 820, the device is not worn, the process terminals. - When the
electronic device 101 is being worn duringoperation 820, theelectronic device 101 may determine a movement strength of theelectronic device 101 inoperation 825 and may determine whether the movement strength is less than a threshold for a predetermined time inoperation 830. If theelectronic device 101 is being worn inoperation 820, and the movement strength maintains less than the threshold for the predetermined time inoperation 830, a biological signal for a resting state is measured (operation 835), and the process may come to an end. - Subsequently, when the movement strength maintains less than the threshold for the predetermined time in
operation 830, which indicates that the user does not move, theelectronic device 101 may perform resting state monitoring inoperation 835. - As such, upon meeting both the condition that the
electronic device 101 is being worn and the condition that the user does not move prior to performing the resting state monitoring, theelectronic device 101 may perform such resting state monitoring inoperation 835. - Since the
electronic device 101 is being worn on the user's wrist, theelectronic device 101 may control thesensor module 170 to measure the speed, acceleration, traveling direction, or slope of theelectronic device 101. Theelectronic device 101 may determine the user's current state, e.g., still, running, or walking, and the posture of the user wearing theelectronic device 101, e.g., the state of moving using a traveling means, based on sensing data measured through thesensor module 170 of theelectronic device 101. Thesensor module 170 may determine whether the user is resting by detecting where theelectronic device 101 is moving slow or the state in which the user moving while wearing theelectronic device 101 stops moving, at least for a predetermined time, based on the determined current state and the moving state. Here, the user's posture refers to a position of the user's body when theelectronic device 101 is a body-worn electronic device. The user's posture refers to a position of the user's head when theelectronic device 101 is an ear-worn electronic device. The user's posture refers to a position of the user's wrist or ankle when theelectronic device 101 is a wrist-worn electronic device. - According to an embodiment of the present disclosure, whether the user is in the resting state may be determined based on the user's current state, moving state, posture, and the movement of the
electronic device 101. According to an embodiment of the present disclosure, a phone use history, such as calling, call receiving, or texting, during a previous predetermined time period may also be used to determine whether the user is in the resting state. For example, even when predetermined conditions to determine the resting state, such as the movement of theelectronic device 101 or the user's current state, while theelectronic device 101 is worn, theelectronic device 101 may trace the usage of theelectronic device 101 and determine that the user is not in a resting state, when the user uses the functions such as calling/receiving or gaming for a predetermined time or more. Additionally, theelectronic device 101 may determine that the user is in a resting state after functions such as using the phone or gaming come to an end. - In one embodiment, the
electronic device 101 measures biological signals (e.g., the user's blood pressure, blood flow, body temperature, respiratory rate, oxygen saturation, cardiorespiratory sound, or blood sugar) when the user is at rest. Theelectronic device 101 determines that the user is at rest when the device is worn and there is little or no movement of the device. For example, the sensor for measuring the heart rate is activated upon determining that the user is at rest, resulting in substantially less power consumption. -
FIG. 9 is a flowchart illustrating an operation for measuring biological information in a resting state by an electronic device according to an embodiment of the present disclosure. For the operations shown inFIG. 9 , it is assumed that theelectronic device 101 is worn from the operations described above in connection withFIG. 8 . - Referring to
FIG. 9 , theelectronic device 101 may determine a variation in movement strength of theelectronic device 101 through thesensor module 170 while theelectronic device 101 is being worn on the user's body in operation 900. According to an embodiment of the present disclosure, theelectronic device 101 may compute a movement value according to the movement of theelectronic device 101 using the acceleration sensor and may compute the movement strength of theelectronic device 101 using the computed movement value. Subsequently, theelectronic device 101 may determine whether the computed movement strength is less than a first threshold inoperation 905. When the movement strength is less than the first threshold, theelectronic device 101 may determine whether the movement strength less than the first threshold lasts for a first time period or more inoperation 910. When the movement strength is not less than the first threshold or when the movement strength less than the first threshold does not last for the first time period or more, theelectronic device 101 may go back to operation 900. - It is noted that when the movement of the
electronic device 101 is less than the first threshold, and for more than the first time period, the foregoing would normally indicate that the user is at rest. However, if this immediately follows a period of strenuous exercise, there will be a significant increase in the heart rate as compared to a routine time when the movement of theelectronic device 101 being less than the first threshold, for more than the first time period. To alleviate this, the electronic device determines whether during a second time period, prior to the first time period, whether there was movement that unusually large, or larger than a second threshold, the second threshold larger than the first threshold. - Accordingly, when there is a larger movement for a second time period before the first time period, the heart rate recovery time may take longer as compared with when there is a smaller movement for the second time period. According to an embodiment of the present disclosure, the heart rate recovery time may be adjusted depending on the level of a previous movement. A method for adjusting the heart rate recovery time is described below with reference to
FIGS. 10A and 10B . - When the movement strength less than the first threshold lasts for the first time period or more in
operation 910, theelectronic device 101 may determine whether the movement strength during the second time period before the first time period is a second threshold or more inoperation 915. In other words, theelectronic device 101 may determine whether there is a larger movement during the second time period before the first time period. By contrast, unless the movement strength during the second time period before the first time period is the second threshold or more, theelectronic device 101 may activate a sensor for measuring a heart rate inoperation 920 and store a heart rate measured in the resting state inoperation 925. On the contrary, when the movement strength during the second time period before the first time period is the second threshold or more, theelectronic device 101 may return to operation 900. Here, according to an embodiment of the present disclosure, when the movement during the second time period is larger, e.g., the second threshold or more, theelectronic device 101 may be implemented to increase the duration of the first time period to recover the cardiac function when going back to operation 900. This is to increase the first time period, if the user has recently engaged in strenuous exercise. - As described above, according to an embodiment of the present disclosure, the
electronic device 101 may measure the user's heart rates whenever meeting the condition that the state of theelectronic device 101 lasts within a predetermined threshold range for a predetermined time. - According to an embodiment of the present disclosure, the user's heart rate may be measured a predetermined time after the user's state has been previously measured while the above condition is met. In other words, the
electronic device 101 may return to operation 900 a predetermined time after the user's heart rate has been measured, and when the above conditions are met, may result in the measurement of a heart rate in the resting state. As such, theelectronic device 101 may re-measure a heart rate when a predetermined time elapses after a previous time of heart rate measurement even when the resting state is determined to come back after the heart rate measurement, thus reducing the number of times that the heart rate sensor is activated. Thus, the energy consumption of theelectronic device 101 may be reduced. - According to an embodiment of the present disclosure, when the
electronic device 101 meets the above condition, a predetermined time elapses since the previous heart rate measurement was done, and theelectronic device 101 is positioned so that the user is highly likely to be in the resting state in light of the user's activity pattern, and theelectronic device 101 may measure the user's heart rate. - The heart rate measured only once in the above manner, or when there are multiple heart rates measured, a weighted average of the multiple heart rates may be used as a resting heart rate depending on the state and position of the
electronic device 101 when the heart rates are measured. - The operation of
FIG. 9 is described below with reference toFIGS. 10A and 10B for better understanding.FIGS. 10A and 10B are graphs illustrating movement strengths according to embodiments of the present disclosure. - Referring to
FIG. 10A , the horizontal axis (X) is a time axis, and the vertical axis (Y) is an axis indicating movement strengths. Here, the “axis indicating movement strengths” refers to a variation according to a direction of a force. For example, it may be considered that when the direction of the force is a plus (+) direction, an acceleration acts in a plus (+) direction of one of, at least, the x, y, and z axes of the acceleration sensor, and an acceleration reacts in a minus (−) direction. As shown inFIG. 10A ,D1 1000 indicates a time period for determining a resting state, D2 1005 a time during which a movement strength corresponding to the user's state or a movement of theelectronic device 101 is between a first threshold (e.g., Level1) and a second threshold (e.g., Level2), D3 1010 a time period during which the movement strength is between the second threshold (e.g., Level2) and a third threshold (e.g., Level3), and D4 1015 a time period during which the movement strength is between the third threshold (e.g., Level3) and a fourth threshold (e.g., Level4). Here, the width of each time period D2 to D4 may vary depending on the threshold range where the movement strength belongs. - For example, the first threshold may be a reference value for determining a state in which the user does not move so that the
electronic device 101 substantially comes to a halt. According to an embodiment of the present disclosure, the first threshold may be a reference value to determine a state in which the user puts aside theelectronic device 101 without wearing it. In other words, when the first threshold lasts for a predetermined time or more, the first threshold may be used to determine such a state that the user places down theelectronic device 101 for, e.g., recharging, without wearing the device. - Further, the second threshold may be a reference value to determine a state in which the user wearing the
electronic device 101 stops moving. According to an embodiment of the present disclosure, although the second threshold is used as a reference to determine whether the sensor for heart rate measurement is activated, for example, any other various references, such as the user's age or place or time of wearing the electronic device, or other various environmental factors, may be used as the reference value. - The third threshold may be a reference value to determine whether the state is a moving state that arises in a daily routine, the fourth threshold may be a reference value to determine whether the state is a walking state, and the fifth threshold may be a reference value to determine whether the state is a running state or engaging in strenuous exercise.
- As shown in
FIG. 10A , when the movement strength lasts for a predetermined time at the second threshold or less, the sensor to measure a heart rate may be activated at thetime 1020 that the predetermined time has elapsed. As such, since the sensor module is activated only when required, battery consumption is reduced. - According to an embodiment of the present disclosure, when the first time period is
D1 1000, the case where the movement strength during the second time period (e.g., D2 1005) before the first time period is exceeds the fourth threshold (e.g., Level4), the profile may mean that the user has engaged in more strenuous activity compared with the profile where the movement strength during the second time period is within the second threshold (e.g., Level2) range. Accordingly, time period D1 should be longer for if the time period D4 during which movement exceeded the fourth threshold (Level4) was long. Accordingly, according to an embodiment of the present disclosure, the minimum heart rate recover time as required before activating the sensor to measure a heart rate may be adjusted depending on the degree of a previous movement. In other words, the time period corresponding to D1 may be varied depending on the duration of D2 to D4. For example, the width of D1 may be more reduced when the movement strength comes in the first threshold from the fourth threshold range than when coming in the first threshold range from the second threshold range. - Meanwhile, although
FIG. 10A represents movement strengths, specifically, variations in acceleration, the degree of a movement may also be recognized in a way as shown inFIG. 10B . As shown inFIG. 10A , the waveform near “0” denotes the case where the acceleration is 0, and this may occur since the waveform fluctuating between a positive value and a negative value is accelerated in the plus (+) direction by the law of action-reaction, and when put on a halt, it is accelerated in the minus (−) direction by the same law. -
FIG. 10B shows magnitudes through x, y, and z values of the acceleration sensor that are shown to be larger than 0 on the graph, and such values may denote impulses. The impulses may be calculated by the followingEquation 1. -
Mag=√{square root over (x 2 +y 2 +z 2)} [Equation 1] - In
Equation 1, ‘Mag’ may denote an impulse, and x, y, and z may denote x, y, and z values, respectively, of the acceleration sensor. - As set forth above, the degree of a movement, i.e., a movement strength, may be determined either by a variation in acceleration as shown in
FIG. 10A or by the absolute magnitude of the acceleration sensor as shown inFIG. 10B . -
FIGS. 11A and 11B are flowcharts illustrating an operation after biological information has been measured in a resting state by an electronic device according to an embodiment of the present disclosure. - Referring to
FIG. 11A ,operations 1100 to 1125 are the same as operations 900 to 925 ofFIG. 9 , and no detailed description thereof is repeated. However, whether the movement strength is the second threshold or more during the second time period before the first time period may be determined inoperation 1115. When the movement strength during the second time period before the first time period is the second threshold or more, the first time period may be adjusted considering the time required for the cardiac function to recover in operation 1117. Here, the adjusted first time period may be rendered to be longer than the previous first time period. In other words, time period D1 is made longer. Here, ‘A’ denotes thatoperation 1125 ofFIG. 11A is associated withoperation 1130 ofFIG. 11B , and ‘B’ denotes thatoperation 1100 ofFIG. 11A is associated withoperation 1140 ofFIG. 11B . - Thus, after activating the sensor to measure a heart rate in
operation 1120 and storing a heart rate measured in the resting state inoperation 1125, theelectronic device 101 may determine whether the movement strength during the third time period (D3) after the first time period is less than the first threshold (Level1) inoperation 1130. For example, when the user does not move with theelectronic device 101 on during the first time period or does not wear theelectronic device 101 so that there is no movement of theelectronic device 101, theelectronic device 101 may determine that the moment is a resting time to measure a heart rate in the resting state. - However, when the user thereafter takes off the
electronic device 101, there may be no movement of theelectronic device 101. In such case, the movement strength during the third time period may maintain less than the first threshold. Whether theelectronic device 101 is worn may be determined inoperation 1135 to determine whether no movement occurs since the user does not actually wear theelectronic device 101. When the movement strength during the third time period is less than the first threshold, it may be determined inoperation 1135 whether theelectronic device 101 is worn in the same manner asoperations FIG. 8 . Unless theelectronic device 101 is determined to be worn inoperation 1140, the process may be terminated. -
FIG. 12 is a flowchart illustrating an operation for storing a result measured based on biological information measured in a resting state by an electronic device according to an embodiment of the present disclosure. Here, theelectronic device 101 may be an electronic device that is performing monitoring to determine a resting state with theelectronic device 101 worn. - Referring to
FIG. 12 , theelectronic device 101 may determine whether the sensor to measure a heart rate is activated inoperation 1200. Theelectronic device 101 may determine whether the resting state comes up based on, e.g., the user's moving state, the movement of theelectronic device 101, or the current position, and upon determining that the resting state comes up, theelectronic device 101 may activate the sensor. Accordingly, when the sensor is activated, theelectronic device 101 may measure a heart rate in the resting state inoperation 1205 and may obtain data to be stored together with the measured heart rate. According to an embodiment of the present disclosure, theelectronic device 101 may obtain information on the current position of theelectronic device 101 when measuring the heart rate inoperation 1210. Subsequently, theelectronic device 101 may store at least one item of place, time of measurement, and use history of application based on the current position information in association with the measured heart rate inoperation 1215. Thereafter, theelectronic device 101 may determine whether there is a request for identifying the measured result from the user inoperation 1220. When there is the request for identifying the measured result, theelectronic device 101 may display the measured heart rate result corresponding to the user's item selection inoperation 1225. -
FIGS. 13A to 13C are screen views illustrating results of measurement of heart rates corresponding to items selected by the user according to embodiments of the present disclosure. - Since the
electronic device 101 is being worn on the user's wrist, theelectronic device 101 may determine the time when the user is in the resting state based on the sensing data measured through thesensor module 170 of theelectronic device 101 and may display a resultant heart rate measured in the resting state. The resultant heart rate measured in the resting state may be stored in association with the date or time or place of the measurement. - Accordingly, when the user selects the date item as shown in
FIG. 13A , the measuredheart rate results 1305 in the resting state may be displayed per date on theelectronic device 101. Accordingly, when the user selects the time item as shown inFIG. 13B , the measuredheart rate results 1310 in the resting state may be displayed per time period on theelectronic device 101. Accordingly, when the user selects the place item as shown inFIG. 13C , the measuredheart rate results 1315 in the resting state may be displayed per place period on theelectronic device 101. As such, the measured heart rate results may be stored in association with date or time or place of measurement, thereby leading to diversified applications. For example, the count of measuring heart rates in the resting state may be set to differ depending on whether theelectronic device 101 is placed in home or work place. For example, when the user is wearing theelectronic device 101 at home, his activity may be less than that while he works. Thus, a weighted frequency for heart rate measurement in the resting state may be increased considering such situation. - Meanwhile, the heart rate result measured in the resting state may be utilized for healthcare services in various manners. According to an embodiment of the present disclosure, the heart rate result measured in the resting state may be used to display a variation in the user's body condition through a tendency in which heart rates change in the resting state.
-
FIG. 14 is a view illustrating a healthcare service using a result of heart rate measurement performed in a resting state according to an embodiment of the present disclosure. - Referring to
FIG. 14 , when agraph 1405 with a measured heart rate of alarger width 1407 than that in agraph 1400 of heart rate results measured in the resting state and accumulated for a predetermined time period shows up, the user may be notified of thegraph 1405. For example, the variation history of heart rates in the resting state may be utilized to recommend cardiography or other medical checkup for users with a variation width exceeding a predetermined standard or may be used as auxiliary material to check up the users' heart and body conditions. - Further, in the
case 1410 where the heart rates automatically measured in the resting state for a predetermined time period steadily decrease as compared with thereference graph 1400, the user's health condition may be determined to gradually get better. By contrast, in thecase 1415 where the user's heart rates in the resting state steadily increase, the user's health condition may be determined to gradually worsen, and its relevant feedback may be delivered to the user. - The difference between the time when the user enters the resting state based on the sensing data to measure a physical movement and the time when the user actually enters the resting state based on a heart rate may be used to determine the user's heart condition and whether there is a danger of sudden cardiac death. For example, when the user with a disease history, such as heart disease or cardiovascular disease enters the resting state but his heart rate is down to the resting state with a predetermined time or more of delay, such information may be useful to calculate the probability of the user's sudden cardiac death. Further, although it is determined that the user's movement is in the resting state while the user is wearing the
electronic device 101, when the user's heart rate measured is significantly higher or lower as compared with a normal resting heart rate, it may be inferred that the user's body is in an abnormal condition. As such, when an abnormal condition occurs in the user's body, an alert may be externally transferred, so that the heart rate information in the resting state may be utilized to early discover a possible emergency. Generally, a sharply increased high heart rate may be observed if the user collapses, e.g., due to cerebral infarction, as compared with the resting heart rate measured in his routine during which he makes little or no movement. A very tiny heart rate may be observed if the user collapses, e.g., due to a faint or heart attack, as compared with the resting heart rate measured in his routine during which he makes little or no movement. - Further, the heart rate result measured in the resting state may be utilized in various manners for healthcare services other than those described above. According to an embodiment of the present disclosure, heart rate results measured in the resting state may be used to calculate calorie consumption through normalization of heart rates.
-
FIG. 15 is a view illustrating an example of displaying a healthcare content using a result of heart rate measurement performed in a resting state by a plurality of electronic devices according to an embodiment of the present disclosure. - Referring to
FIG. 15 , when biological information is configured, theprocessor 120 of theelectronic device 101 may perform control to transfer the configured biological information to anotherelectronic device 103 communicably connected with the electronic device. In other words, theelectronic device 101 may display a screen indicating that a healthcare application is running. Theelectronic device 101 may configure a measured heart rate result or measured heart rate result-based information for anelectronic device 103 interworking with theelectronic device 101 and may provide the configured information to theelectronic device 103. In response, theelectronic device 103 may display a healthcare screen based on a result of monitoring a heart rate in the resting state, which includes more detailed items as compared with those of theelectronic device 101. - As shown in
FIG. 15 , the heart rate result measured in the resting state may be used to calculate calorie consumption through normalization of heart rates, and a content may be displayed according to an exercise mode based on the calorie consumption. That is, the user's calorie consumption may be calculated based on a variation in heart rate and the user's movement. Generally, as the user does a physical activity, such as exercise, his heart rate increases. The degree by which the heart rate has been increased may be used to calculate the degree of the user's physical activity and calorie consumption. Here, although the user's heart rate is increased as he attends a physical activity, the width by which the heart rate is increased may vary depending on the user's body conditions. Accordingly, the degree of the user's physical activity and calorie consumption might not be exactly calculated only with the information that his heart rate has been increased. The information on the user's heart rate in the resting state may be used to more correctly calculate his calorie consumption and degree of physical activity. - The maximum heart rate during exercise per age is generally fixed. Therefore, when the user's heart rate in the resting state is known, an available heart rate variation range per user may be obtained, and the degree by which the user's heart rate currently measured is positioned within the available heart rate variation range per user may be quantized and represented. As such, the quantized heart rate variation may be used to derive a formula for the user's calorie consumption. Here, the user's heart rate may be varied by exercise and may also be increased or decreased by strain/discomfort/sleep/rest or other changes in his physical condition. According to an embodiment of the present disclosure, the causes for quantized heart rate variations may be differentiated using sensor information obtained from an inertia sensor, a location sensor, an air pressure sensor, a GSR sensor, or a temperature sensor, and different calorie consumption formulas may apply to their causes, thereby allowing the calorie calculation increased accuracy.
- For example, when the user is determined to be in a workout, quantized heart rate variation-based calorie consumption formulas may apply depending on the state and type of the exercise, and when the user is determined to be in sleep, a calorie consumption formula optimized for a sleep state may apply to increase the accuracy of calculation of calorie consumption.
