The monitor may include a haptic feedback means, such as pulse emitting device to aid stabilisation of emotions and to increase the energy levels of a user.
BRIEF DESCRIPTION OF THE FIGURES
Embodiments of the present invention will now be described in more detail with reference to the accompanying Figures: Figure 1 is a schematic illustration of a flow chart for operation of the system according to one embodiment of the present invention; and Figure 2 is a graph of the anxiety levels detected by a monitor according to one embodiment of the present invention attached to the skin of a user.
DETAILED DESCRIPTION
With reference to Figure 1, the monitor 1 comprises at least one sensor, a power supply, a memory which stores data obtained from the at least one sensor, and a wireless transmitter which is operative to transmit the data to a wireless receiver, upon receipt of an authorisation signal. The at least one sensor is a photoplethysmogram sensor which is operative to obtain data relating to: (i) a pulse duration (T), (ii) phase differences (5) occurring between a forward pressure wave peak and a reflected pressure wave peak, and (iii) a goodness-of-fit correlation (13) between a waveform shape and a continuous probability function in order to determine an anxiety level of the wearer.
By using a photoplethysmogram (PPG) sensor, the pulse waveform of a user can be visualised in software through the measurement of blood volume changes in tissue. Each emotional state of a user has been found to provide a different pulse waveform.
The at least one sensor includes an accelerometer operative to monitor a user's movement; an infrared (IR) sensor operative to measure a user's temperature; and a pulse oximeter operative to measure a user's blood oxygen level.
The monitor 1 further comprises light emitting diodes (LED) configured to provide a visible indication to the user of the status of the monitor 1, for example to provide a visible indication of one or more of: charging status, data transmittal status, data monitoring status, and/or battery level status.
The power supply comprises an internal rechargeable battery configured to power the monitor for at least one week. The monitor also comprises a charging port to enable one or more onboard batteries to be recharged.
The monitor comprises a housing configured to substantially encompass the sensors, the power supply, the memory which stores data obtained from the at least one sensor, and a wireless transmitter in order to protect these components from exposure to the external environment, to increase durability of the monitor, and to prevent for example dirt and/or water ingress.
The housing may comprise a synthetic plastics material and preferably comprises a transparent portion.
In the illustrated embodiment, the monitor 1 is paired, by Bluetooth (RTM) connectivity, to a mobile communications device 101 (for example a smartphone or tablet) prior to being positioned on a body of a user.
The monitor 1 is then placed in position on a wrist of a user. It is however to be understood that the monitor may be positioned adjacent any suitable area of the body of the user where pulse readings can be obtained. Suitable areas of the body include, for example, upper arm, wrist, temple, forehead, calf, ankle, or any combination thereof.
The monitor may comprise any suitable attachment means for securing the monitor in place in contact with a user's skin.
A pulse emitting device 2 is worn on the wrist of the user. The pulse emitting device 2 comprises an electromagnetic coil and is in communication with the mobile communications device 101.
In use, the sensors of the monitor 1 collect data which are stored within the memory of the monitor 1 and wirelessly transmitted to the mobile communications device 101.
Individual pulses can be classified into different emotional states of the user. Successful classification requires four parameters to be determined for each pulse: the pulse duration, the phase difference between the forward and reflected waves, and the ratio of the forward and reflected peaks, and a goodness-of-fit correlation. Each emotion of a user has been found to provide a specific waveform shape.
When the monitor 1 is not in communication with the mobile communication device 101, the memory continues to store data from the sensors and then when the mobile communication device 101 is in communication with the monitor 1, the wireless transmitter is configured to allow all of the stored data obtained during the period of non-communication to be transmitted to the mobile communication device 101, either automatically, at predetermined time intervals, or on request.
The results of the obtained data, and identified waveforms, are then provided to the user, on the mobile communication device 101, with lifestyle recommendations. The display of the mobile communication device 101 may provide a visual indication as to the anxiety level and/or impatience level and energy level of the user The display of the mobile communication device 101 may for example, in response to the obtained data, present a calming image or a calming video on determination of a level of anxiety above a predetermined level of anxiety. It is to be understood that the display may suggest to the user that a calming image or video may be presented as a result of the determined level of anxiety of the user.
The speaker of the mobile communication device 101 may present or play one or more images and/or soundtracks on determination of level of anxiety or a level of impatience (for example a level of anxiety or impatience greater than a predetermined level of anxiety or impatience) by the monitor.
It is to be understood that the display may suggest to the user that a sound, video or soundtrack may be played as a result of the determined level of anxiety of the user.
The soundtracks, images and/or videos may be selected by the user from a library of soundtracks, images and/or videos.
By listening to and/or looking at the images, videos and/or soundtracks provided by the mobile communications device 101, the anxiety levels of a user may be reduced over a period of time towards a non-nalised level.
Table 1 below sets out some further combinations of sets of different characteristic factors and how these indicate a particular emotion type. Some examples of emotion types are: of: impatience, anxiety, fear, frustration and grief However, it is understood that different emotion types or even sub-classes of emotion types of the wearer are now able to be detected and measured by selecting categories and combinations of the characteristic factors.
It is further understood that intelligent systems, which may include machine learning algorithms or other artificial intelligence (Al) devices may be used to improve sensitivity or reliability of emotion selection and measurement. Such as machine learning algorithms or other artificial intelligence (Al) devices may include further inputs from other devices or external or environmental data sources which are processed by a processor, such as a microprocessor. Other data sources, include for example, weather conditions including ambient temperature, location, time of day and total time that the wearer has been awake.
Examples of the characteristic factors are: L: pulse duration, 5: phase difference of peaks (time between systolic and diastolic peaks), R systolic/diastolic peak heights ratio and p: shape parameter, "goodness of fit".
Emotions Characteristic factors Impatience 0.57 < [< 1.0; 0.25 < 5 / L < 0.42; R 5.0 0.57 < L < 1.0; Of L < 0.17; p >4.2 Anxiety 0.57 < L < 1.0; 0.42 < OIL <0.60; p <5.3 0.57 < L < 1.0; 0.25 < 0/ L < 0.42; 4.3 < p <5.3 Fear 0.57 <L<1.0; 0.17 <5 /L<0.25 Frustration 0.57 < L < 1.0; 0.25 < 5 / L < 0.42; 3.3 < p <4.3; R >5.0 0.57< L <1.0; 5 / L <0.17; 3.3< p <4.3 Grief L < 0.57 0.57 < L < 1.0; 5 / L < 0.17; p 3.3
Table 1
The pulse emitting device 2, on activation by a user via the mobile communications device (activated wirelessly by for example Bluetooth (RTM) connection) 101, generates pulse electromagnetic fields (PEMF) having a specific set of frequencies. The frequencies are selected to have a therapeutic benefit to the user to reduce the associated negative effects of raised levels of anxiety on the user. The frequencies are user specific and selected as a result of the user's data determined by the monitor.
As shown in Figure 2, the levels of anxiety of a user are measured, at regular intervals, using the monitor of the present invention over a predetermined time period. The determined levels of anxiety trigger an outcome from the pulse emitting device 2 (in the generation of PEMF) and/or from the mobile communications device 101 (in the generation of sounds, videos and/or images) in order to reduce the anxiety levels of a user efficiently and effectively.
The system of the present invention therefore, as well as detecting and measuring a particular emotion type, may be used to provide user specific recommendations for reducing particular levels of stress or anxiety or fear, for example by presenting one or more images, sounds and/or videos together with the generation of pulse electromagnetic fields (PEMF) or other types of haptic feedback. As a result of identified levels of anxiety or impatience of the user, these recommendations or feedback cues, may be displayed or played in order to reduce anxiety levels and to increase energy levels of the user.
It will be appreciated that the embodiments hereindescribed are examples only and that variation may be made to them, for example by detecting and measuring different variables relating to different moods (or energy levels) and combining and aggregating these variables in different ways.
