Technical Field

The invention relates to wearable equipment, in particular to wearable prompting equipment, a corresponding prompting method thereof and an intelligent watch.

Background

With the miniaturization of electronic devices and the promotion of sensing technologies, wearable electronic devices such as smartwatches, bluetooth headsets, rings, etc. are also continuously developing toward compactness, multiple functions, and high endurance. Among these, configurable devices with timely and accurate security alarm functions are an urgent need for many users, especially users who have the elderly and children who need care at home.

Existing child safety watches may send a prompt to a parent's cell phone for a pre-set safe zone (e.g., 500 meter range of motion centered around home and school, respectively) when the child wearing the watch leaves the safe zone. However, because of the everyday path between security areas (e.g., a child sitting in a school bus to school), such daily prompts as entering and leaving a security area tend to be cumbersome and do not help parents clarify the actual danger signals.

For this reason, a wearable device and a use scheme thereof capable of accurately prompting a safety condition are required.

Detailed Description

Preferred embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While the preferred embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

A wearable device is a portable device that can be worn directly on the body or integrated into the clothing or accessories of a user. With the development of the technology, the wearable device can realize powerful functions through various built-in hardware sensors, software support and data and cloud interaction. Wearable devices exist in the form of portable accessories that have a part of computing functions and can be connected to mobile phones and various terminals, and the current mainstream forms include watches (including products such as watches and wristbands) supported by wrists, shoes (including shoes, socks or other wearing products on legs in the future) supported by feet, glasses (including glasses, helmets, headbands and the like) supported by heads, and other various forms such as smart clothes, bags, crutches, accessories and the like.

The wearable device is easier to acquire various kinds of information of the wearer stably for a long time due to the wearable characteristic. In order to accurately prompt the safety condition of the wearer, the wearable device is particularly suitable for being implemented as a device which can be worn for a long time and is easy to obtain various physiological and motion sensing data of the wearer, such as an intelligent electronic watch or other wrist-wearing devices with watch functions. In other embodiments, the wearable device of the present invention may have other forms, for example, being implemented as electronic eyeglasses or as a sole sensing device. In some embodiments, the wearable device of the present invention may be a device having multiple wearable modules at the same time, e.g., a wristwatch including a bluetooth-connected foot-acquisition module, or the like.

The existing safety prompting device is represented by a special mobile phone for the old and a safety watch for children. The mobile phone dedicated for the elderly cannot well prompt children or other related persons (e.g., community service personnel) for danger because it cannot be carried around and requires additional calling operations (e.g., the user needs to make a call for help by himself). The child safety watch is capable of actively sending a message to the parent's cell phone, but is limited to a preset safety zone, for example, when a child wearing the watch leaves the safety zone, a prompt is sent to the parent's cell phone. However, because of the everyday path between security areas, such daily prompts as entering and leaving a security area tend to be rather cumbersome and do not help parents in defining the actual danger signals.

In view of this, the present invention provides a wearable device capable of accurately performing a safety prompt and a corresponding safety prompt scheme thereof. Fig. 1 shows a schematic composition diagram of a wearable device according to an embodiment of the invention. Wearable device 100 may include functionality to secure alerts to associated terminal devices and may therefore also be referred to as a wearable alert device. In one embodiment, the wearable device may be implemented as an electronic device that may be worn on the wrist, e.g., a smart watch.

As shown in fig. 1, the wearable device 100 includes a data acquisition device 110, an evaluation device 120, and an alarm device 130, wherein the data acquisition device 110 may be configured to acquire data, the evaluation device 120 may be configured to determine a current status level of the wearer from at least two status levels according to the data acquired by the data acquisition device 110, and the alarm device 130 may automatically notify an associated terminal device in a corresponding notification manner based on the determined current status level, that is, may automatically notify in corresponding different notification manners according to the current danger level.

Here, the associated terminal device may be a device that is bound to the wearable device in advance, and may particularly be a terminal device belonging to a related person other than the wearer. For example, the associated terminal device may be a parent's smartphone and/or bracelet that was previously bound with the wearable device 100 of the present invention implemented as a child-resistant watch. Thus, through the intervention of other related personnel, it is easier to judge and even help the wearer to escape from danger.

The data acquisition device 110 may acquire data directly by acquiring and may include a plurality of sensors for acquiring relevant data. In one embodiment, the data acquisition device 110 may include at least a wearing sensing sensor for sensing the physical condition of the wearer by wearing and a positioning sensor for determining the position of the wearer, so that the wearable device 100 can determine an abnormal or emergency situation at least from the two larger dimensions of the physical condition and the position of the wearer and notify the terminal device of the guardian if necessary, for example, directly make a call to a parent.

The wear perception sensors for detecting the wearer's physical condition may comprise wear posture detection sensors for characterizing the wearer's posture and/or physiological condition sensors for characterizing the wearer's physiological condition, thereby enabling the assessment device 120 to rationally assess the wearer's current physical condition from two more refined dimensions of the wearer's motion posture and physiological condition. For example, the wearable posture detection sensor may include a gyroscope and an accelerometer for detecting the movement state, and the physiological condition sensor may include a pulse rate sensor, and the data of the sensors may be comprehensively determined by the evaluation device 120, for example, to determine that the wearer is running, running too fast, or in other physical conditions.

The positioning sensors may then include sensors that determine where the device 100 is located due to various principles. In one embodiment, the positioning sensor may be implemented as a global navigation satellite system (GPS) receiver to determine the location of the device from GPS signals. Alternatively or additionally, the positioning sensor may be implemented based on communication with a cellular network, WiFi, or other navigation system (e.g., beidou system).

The obtaining of the data further includes obtaining environmental data, and the obtained data may be directly collected by the device 100 or obtained from a cloud. To this end, the data acquisition device 110 may further include an environmental sensing device for sensing an environmental condition of the wearer. In some embodiments, the environmental sensing may be implemented as a sensing of the wearer's surroundings, and thus the environmental sensing means may comprise environmental sensing sensors for sensing the wearer's surrounding environmental conditions, e.g. based on liquid contact sensors and temperature sensors installed in the device. In other embodiments, the environmental awareness may be realized as a perception of a more meaningful environmental condition, and thus the environmental awareness means may comprise environmental data acquisition means for acquiring, from a server side, an environmental condition of a large environment in which the wearer is located. The environment data acquiring apparatus may be, for example, a networking module used by the wearable device 100 for data transceiving. The networking module may obtain from the network the current condition of the environment in which the wearer is located, in particular an abnormal or (potentially) dangerous condition, based on the device position determined by the positioning sensor. For example, the positioning sensor displays that the wearer is at an intersection, and the networking module can acquire a traffic light change schedule of the intersection from the server. For another example, the networking module may learn from the server that the wearer is passing through an area that has been flooded too deeply with heavy rain, etc.

In one embodiment, the data acquisition device 110 may include a plurality of sensors described above for acquiring environmental, physiological, motion, and location information, such as, for example, a motion sensor, a pulse rate sensor, a respiration rate sensor, an orientation sensor, an ambient light sensor, a proximity sensor, and a location sensor. In another embodiment, the sensors included in the data acquisition device 110 may be implemented as: one or more of the following: accelerometers, magnetometers, gyroscopes, photovoltaic cells, charge coupled devices, global navigation satellite system receivers, Wi-Fi transceivers, cellular telephone transceivers, and assisted GPS receivers. These sensors may be used alone or in combination to provide data in various dimensions, for example, heart rate information obtained by a pulse rate sensor may be used alone as one dimension of the physical condition data, or may be used in conjunction with, for example, motion sensors, accelerometers, and water ingress sensors, etc., to provide a description of the current motion (e.g., running or swimming) condition of the wearer.

Thereby facilitating the assessment device 120 to perform an all-round assessment of the current safety status of the wearer based on the multi-dimensional data acquired by the data acquisition device 110.

In one embodiment, the evaluation device 120 requires a security evaluation based on, among other things, the current location of the wearer. In the present invention, it is still possible to set a safe area and/or a safe route for the wearer. Unlike the prior art, which simply sets the range of motion within a predetermined distance centered around a home or school, the wearable device of the present invention enables more flexible security zone setting. For example, the security area may include, for example, a daily school bus route or the like in addition to areas within or near homes and schools. Further, a security period of the security area may be set. For example, the school bus path is determined as a safety area or the like only at the school hours.

The assessment device 120 can maintain the risk level baseline as a whole at its default normal level while the wearer is within the safe area. For example, if a wearer is detected falling within a school, the choice may be to not notify or only message the guardian. And if the wearer falls in an otherwise unsecured area, the choice may be to notify the guardian directly, or in a more easily learned manner (e.g., ringing or vibrating).

Further, the assessment device 120 can adjust the baseline risk level at which the wearer is located down when the wearer is currently within an unsafe area. The unsecure area may include areas of normal activity of the wearer and/or areas outside of the route, such as areas outside of a prescribed school, home, and round trip route. In other embodiments, the unsecure zone may also include high risk active zones and bursty unsecure zones determined based on environmental conditions. It should be understood that the risk level baseline of the evaluation device 120 may be scaled down in stages for different risk levels of the unsafe zone.

Here, the "risk level baseline" may be a value representing the degree of abnormality of the data triggering the state level determination corresponding to the higher risk level, and may reflect the stress level of the wearable device to the risk. In other words, in the case of a normal baseline, a general sensory data anomaly (e.g., an anomaly where some data deviates by 10% from the normal value) will not trigger a device alarm, while in the case of a baseline that is adjusted down, a general sensory data anomaly (e.g., an anomaly where the data also deviates by 10% from the normal value) will also trigger a device to determine or make a more significant alarm of the status level of the higher-risk video.

For example, if the wearer's (e.g., a 10 year old child) has a resting heartbeat of 80 beats/minute, the normal risk level baseline for the heartbeat may be, for example, 160 beats/minute. When the wearer is in a safe area (e.g., on a school playground), when the wearable device measures his heart rate up to 155 beats/minute, it may be determined that the wearer is performing normal strenuous athletic activity on the playground (e.g., sprint training on a sports class), and the current status level is assessed as "safe". When the wearer is in an unsafe area, the normal risk level baseline for the heartbeat may be adjusted down, for example, to 140 beats/minute. At this point, if the wearable device measures its heart rate up to 155 beats/minute, it determines that the wearer is at a current status level of higher risk level, assesses as "medium risk" and short-messages the parents.

Different risk level baseline evaluation modes can be provided for different acquired data. The value of the risk level baseline may be a threshold value that is the same as the unit of the value of the acquired data, or may be a threshold percentage that indicates the degree of deviation from the normal value range. The "lowering" risk level baseline mentioned in the present invention may be a risk assessment baseline for adjusting all data, or a risk assessment baseline for adjusting part of data selected based on a scene requiring "lowering", and the degree of "lowering" or the shift of the baseline for each data may be different according to a specific scene. The evaluation means may comprehensively perform the state grade evaluation based on the specific kind of data exceeding the baseline, the degree to which each kind of data exceeds the baseline, and the like.

In any case, in the case of a lowered risk level baseline, since minor fluctuations in data also cross the baseline, the evaluation device is more sensitive to data anomalies, it is easier to determine the status level corresponding to a higher risk level, and the alarm device is also easier to notify in a more noticeable manner.

In particular implementations, wearable device 100 of the present invention may include different numbers of status levels. For example, in a simpler embodiment, only two status levels, hazardous and safe, may be included. In another embodiment, three state levels, low, medium and high, may be included. In one embodiment, four state levels of low, medium, high, and very high may be included. In a more complex embodiment, the evaluation device 120 may evaluate the dangerous content itself and give different dangerous levels and corresponding notification modes according to different dangerous contents. The status level may be defined as a default or based on the user's device. Regardless of how much the ranking is made, the device 100 notifies the supervisor in a manner that is more easily known at the status level corresponding to the higher risk level. For example, in the case where the device is determined and notified at three risk levels, low, medium, and high, only the low risk activity content evaluated may be displayed on the guardian's terminal device when a low risk status level is detected (e.g., the child is running in a school playground) (e.g., a message "child is running in playground" is sent to the parent's cell phone, and no cell phone shock or ringing is caused); when a moderate risk status level is detected (e.g., a child has fallen down by running), the tremology or ringing of the terminal device may be triggered while the content is displayed on the guardian's terminal device; when a high risk level is detected (for example, abnormal fast heartbeat after falling or arm movement amplitude is detected to determine that the child runs, falls and is injured), the guardian can be directly dialed and the danger assessment content is informed at the same time.

In the case of a plurality of status levels, the evaluation device 120 may further subdivide the risk of the unsafe zone, for example, the risk level baseline for the conventional unsafe zone may be shifted down by one gear, and the risk level baseline for the high risk zone or the emergency abnormal zone within the unsafe zone may be shifted down by two gears. For example, a swimming pool may be considered a high risk area, a return home in heavy rain may be considered a high risk area as well, and the alarm level may be increased for abnormal conditions of the same physical condition or location. For example, frequent arm swing gestures within a swimming pool may directly trigger a high level alarm of suspected drowning.

Further, when the wearer enters a certain range or relatively determined insecure area of the responsible person, the wearable device 100 may automatically bind the monitoring device of the insecure area and unbind when leaving the area. For example, when a wearer enters a swimming pool, the device 100 automatically binds to a monitoring notification device of the swimming pool, so that when a dangerous condition such as drowning of a child wearing the device 100 is detected, the device automatically notifies parents of the device and also notifies a monitoring room or a lifesaver of the swimming pool. The binding is automatically contacted when the wearer leaves the pool.

Alternatively or additionally, the risk level baseline may be adjusted down based on one or more physical condition data of the wearer. Specifically, the data acquisition device 110 determines whether the wearer is currently in a potentially dangerous physical condition based on the physical condition of the wearer; and the evaluation device 120 adjusts the current risk level baseline at which the wearer is located when the wearer is currently in a potentially dangerous physical condition. For example, if the temperature sensor senses that the wearer is currently fever, the evaluation device 120 may more readily determine that the wearer is at a dangerous level and the alarm device 130 may increase the alarm level accordingly for the same abnormal physical, location or environmental condition.

As described above, the evaluation device 120 can adjust the risk level baseline low when the wearer is in an unsafe area and/or in a potentially dangerous physical condition. The above-described determination of whether the body condition is in an unsafe area or potentially dangerous may be made by the data acquisition device 110 as described above. In other embodiments, the above determination may be performed by the evaluation device 120 in a centralized manner. In other words, in different implementations, the data acquisition device 110 may have a certain determination function, and may also only perform the function of data acquisition, and the invention is not limited herein.

As described above, based on the data acquired by the data acquisition device 110, the evaluation device 120 can not only evaluate the current risk level, but also determine the current status content of the wearer, and the alarm device 130 can automatically send the current status content of the determination to the terminal device of the guardian.

For example, when the positioning sensor shows that the child is in the swimming pool area, the posture detection shows that the arm of the child frequently swings, the physiological detection shows that the heart rate is too fast, and the water inlet device display device is under pressure to enter water, the evaluation device 120 may determine the danger level as high, and determine the dangerous scene as suspected drowning, and the alarm device 130 may send dangerous content (e.g., "suspected drowning") to the parents and simultaneously dial the parents 'mobile phone, and may directly send a distress signal to the ring of the rescuer's hand, who is bound when entering the swimming pool.

As another example, in an insecure area, the device 100 implemented as a wristwatch detects a continuous fall signal, and the wearer (child) continues to be in an extremely stressful state (too fast heart rate), then the evaluation device 120 may determine the risk level as high, and determine the dangerous scene as suspected to suffer from "campus blush", and the alarm device 130 may send dangerous content (e.g., "suspected to suffer from blush outside the school") to the parent and dial the parent's phone at the same time. Even a police station or a security administration site near a dangerous situation may be contacted directly to avoid children continuing to be in a dangerous situation.

In some embodiments, the wearable device 100 may further include a sound recording device or a camera. For example, the device 100 may be arranged with a microphone and/or a camera to enable conventional voice, video call or other shooting or recording functionality. The recording/photographing device can also be used in the safety prompting scene of the invention. For example, when the evaluation device 120 determines that the wearer is currently in a high risk level, the recording and/or photographing device may be automatically turned on and record and/or record, take a picture, and may automatically or if selected by the guardian send the recorded content to the associated terminal device (e.g., the guardian's terminal device). For example, in the scene of suspected "backrush" described above, when the evaluation device 120 determines that the risk level is high and determines that the dangerous scene is suspected of suffering from "backrush", the apparatus 100 may automatically turn on the recording and shooting mode and automatically send the environmental recording and photo to the mobile phone of the parent, thereby facilitating the parent's judgment of the scene and more conveniently finding and certifying the backrush when the "backrush" behavior really occurs. In other embodiments, the recording/photographing device may also be a part of the data acquisition device 110. For example, the recording/photographing apparatus may be turned on and data recording may be performed in a certain dangerous scene determined. The evaluation device 120 can analyze the scene sound specifically, determine the actual location or current situation of the child, and so on.

In different implementations, the data acquisition device may have different functions or modules. Fig. 2 shows an example of a wearable device 200 of the present invention. As shown, the data acquisition device 210 may include a plurality of modules, and specifically may include a security area determination module 211, a wearing gesture detection module 212, an emotion perception module 213, an environmental data acquisition module 214, and a body-surrounding environment perception module 215. The safety zone determining module 211 may determine the safety zone by the above positioning sensor in combination with a preset safety zone range, for example. The wearing gesture detection module 212 may be implemented by the wearing gesture sensor above, for example. The emotion sensing module 213 can perform emotion judgment by collecting physiological data of the wearer through the physiological condition sensor. In addition, the environmental data acquisition module 214 and the environmental awareness module 215 can be implemented by the networking and sensor portions of the environmental awareness apparatus, respectively.

The evaluation device 220 can combine one or more risk factors provided by the above modules to determine the risk level of the current state of the wearer (preferably, determine a specific risk scenario), and then notify the alarm device 230.

Therefore, the wearable device disclosed by the invention is combined with more-dimensional data judgment, and a simple daily non-safety area is not used as a unique judgment mode, so that invalid disturbance to a guardian is reduced; furthermore, through grading dangerous scenes, parents can be prompted in a more reasonable mode, and the effect of safety protection on wearers is being played.

In one embodiment, the wearable device of the present invention is particularly suitable for implementation as a smart watch, e.g., a child safety watch. Fig. 3 shows a block diagram of a security prompt smart watch according to the present invention.
