Description

-I-
System and Method for Pulse Rate Reduction The present invention relates to a system and method for providing an intervention to a user in order to reduce the user's pulse rate in a situation for example where they are 5 stressed, angry or emotionally overwhelmed.
In classroom environments children have the propensity for their emotional state to change due to several factors. This often leads to an escalation which manifests in bad behaviour or distress. Action is then taken to deal with this symptom such as removing the child from the situation or disciplining the child. This takes significant time for the teacher and can also lead to significant disruption to the class.
The present invention has been devised with children and/or schools in mind however is not limited in this regard. It is equally applicable to helping adults regulate their emotions 15 and manage stress and anxiety.
According to the present invention there is a system for providing an intervention to a user where the intervention is for reducing the heart rate of a user, the system comprising: a sensor arrangement for sensing a property of a body of the user and outputting a sensor output representative of the property sensed; and an output device for outputting an intervention to the user, the output device being in communication with and separate from the sensor arrangement; wherein the system is configured to select an intervention from a plurality of interventions dependent on the determined property and output the selected intervention The present invention therefore acts to reduce a user's heart rate and thus by doing so reduces stress level, anger level and/or emotional wellbeing. The intervention provided therefore aids the user before the user reaches a higher stress level which would typically lead to significant disruption of the class and a high level of anxiety for the child. While known activity trackers can show a user his/her heart rate, the present invention not only identifies a property of the user but outputs an intervention selected dependent upon the measured property.
The property is preferably a physical property of a user such as pulses emitted by blood passing through the body of the user, electrical impulses, galvanic skin response, sweat and/or blood oxygen levels.
The output device is preferably in wireless communication with the sensor arrangement.
The sensor arrangement is preferably arranged to be secured to a user and further preferably comprises a securing arrangement for securing the sensor arrangement to the 10 user.
The intervention is determined dependent upon sensed property (such as pulse rate), however other inputs may also be used for further determination or modification of the intervention. For example, other inputs may be identification of the user such that 15 selection is made in part dependent upon the individual user.
It will be understood that the output device is separate from the sensor arrangement in the sense that they are distinct from one another. It will be appreciated that the sensor arrangement and output arrangement may communicate via a wired connection, however it is preferable that the output device and sensor device communicate wirelessly, even more preferably via Bluetooth.
The sensor arrangement may comprise more than one sensor.
The sensor arrangement is beneficially a wearable sensor arrangement.
The sensor arrangement may comprise a headband for carrying the one or more sensors to be worn by a user. The headband may carry the sensor arrangement for measuring pulses at one or both temples of the user.
The sensor arrangement is preferably arranged to repeatedly determine the property of the user and the system is configured to change the output intervention dependent upon a change in the property determined. This further improves the effectiveness at lowering the user's heart rate.
The system can therefore modify the intervention dependent upon the determined property. 5 For example, if the property is pulse rate and the pulse rate of the user continues to rise, the intervention can be modified, and/or an additional intervention output. The additional intervention could for example be for triggering the attention of a teacher.
The system is preferably arranged to monitor the sensed property and in the event of a predetermined change in the sensed property (e.g. pulse rate keeps rising for a predetermined time frame, sudden rise in pulse rate) an output signal is transmitted to a remote second output device, where an output is emitted by the remote second output device indicative of the predetermined change.
This provides a significant benefit in the event of a sudden change in the property of a user and where they may need additional help. The remote output device may be a device accessible by a teacher for example meaning the teacher is quickly aware that the normal intervention is not having the required effect and further assistance is required. The predetermined change may as examples only be that the pulse rate keeps rising for a predetermined time frame or that there is a sudden rise in pulse rate.
The intervention output by the output device preferably comprises one or more of a visual output (e.g. instnictional video such as yoga or breath control, calming sights, stories, games and/or tasks) and an audible output (story, music). The intervention is preferably 25 interactive.
The system is preferably further configured such that the selected intervention output is partially dependent upon a secondary/further input. Such an input may be an attribute personalised to a particular user, such as predetermined information based on the effects certain inventions have to that user. For example, a particular intervention might be particularly suitable for one user at a highly stressed level, whereas an alternative intervention might be suitable for another user.
The output device preferably comprises a screen for providing a visual intervention to the user and/or comprises a speaker for providing an audible intervention to the user.
The output device preferably comprises a computing device.
The computing device preferably comprises a processor configured to cause the output device to output the intervention to the user selected from a plurality of different interventions dependent upon the sensed property.
The sensor arrangement preferably further comprises a transmission module for transmitting the sensor output to the output device.
The sensor arrangement preferably further comprises a processor configured for 15 determining a property such as pulse rate from the sensor output.
The sensor output is preferably transmitted to the output device at regular time intervals. It is preferable that a signal representative of the property is transmitted.
The system is preferably configured to compare the determined pulse rate to a look up table matching interventions to corresponding pulse rate ranges and based on this comparison select the appropriate intervention(s) for the determined pulse rate. This is preferably performed by software running on the output device.
Accordingly, the determined pulse rate determines the appropriate intervention or interventions. For example, if a determined pulse rate falls within a predetermined range there may be one or more appropriate interventions which may be presented in sequence or may be presented to the user for selection. Thus, if a predetermined threshold pulse rate is determined the appropriate intervention will be made.
Also according to the present invention there is a method of reducing the heart rate of a user, the method comprising: sensing a property of a user's body; outputting a sensor output representative of the property; selecting an intervention from a plurality of interventions dependent on the property; and outputting the selected intervention.
The method preferably further comprises repeatedly sensing the property of the user and 10 changing the intervention dependent upon a predetermined change in the sensed property.
It is therefore beneficial to sense the property (such as pulses) at regular intervals (such as every five seconds) as the intervention is being delivered and change the intervention if there is sufficient change in the determined property. For example, this might occur if the pulse rate change into a different invention 'band' or may occur of there is a predetermined rise over a predetermined time frame indicative of stress level of the user increasing The method preferably further comprises monitoring the property and in the event of a predetermined change in the property (e.g. pulse rate keeps rising for a predetermined time frame and/or sudden rise in pulse rate) transmitting an output signal to a remote output device, where an output is emitted by the remote output device indicative of the predetermined change.
The property preferably comprises pulses emitted by blood passing through the body, and 25 wherein the method further comprises determining a pulse rate of the user from the sensor output.
The method preferably further comprises comparing the determined pulse rate to a look up table matching interventions to corresponding pulse rate ranges and based on this 30 comparison select the appropriate intervention(s) for the determined pulse rate The sensed property may alternatively comprise one or more of electrical impulses (measured for example by EEG), galvanic skin response, sweat and/or blood oxygen levels.
Aspects of the present invention will now be described by way of example only with reference to the accompanying drawings where: Figure 1 is a schematic representation of an illustrative embodiment of the present invention.
Figure 2 is a further schematic representation of an illustrative embodiment of the present invention.
Referring to Figure 1, an illustrative embodiment of the present invention is presented.
There is a wearable sensor arrangement 2 in the form of a headband 3 that measures a property such as pulses from the superficial temporal artery and where measurement can be made at one or both temples. It will be appreciated however that the claimed invention in a broadest sense is not limited to provision of a wearable sensor arrangement in the form of a headband nor that the sensor arrangement 2 measures only pulses. Other suitable sensor arrangements 2 m may be utilised such as wrist-based monitors 4. This depends to some extent upon the property to be measured. Other suitable properties may be electrical impulses, galvanic skin response, sweat and/or blood oxygen levels, and sensor arrangements suitable for such measurement may be utilised such as EEG sensors.
The following description will be made with respect to pulse monitoring. The headband/wristband 3,4 each comprise a securing arrangement 5 which may comprise a buckle or hook and loop type arrangement for securing the pulse monitor 2 to the user. The wearable sensor arrangement 2 further comprises a sensor arrangement 6 comprising one or more individual sensors. In the illustrative embodiment of a headband 3 two individual sensors may be provided for each measuring pulses at individual temples and the outputs from each compared to ensure a pulse has been measured rather than an external influence. The sensor arrangement 6 further comprises a processor 8 for receipt of a sensor output from the one or more individual sensors and from this sensor output determines a pulse rate. The sensor arrangement comprises communication means 10 such as a Bluetooth transmission module for communication with a corresponding Bluetooth receiving module 11 at a remote output device 12 The remote output device 12 may in a broadest sense only be suitable for outputting an intervention to a user in response to a predetermined signal from the sensor arrangement. Accordingly, the output device beneficially comprises any suitable computing device capable of receiving a signal from the sensor arrangement and in response to receipt of such a signal outputting an intervention. A suitable computing device preferably has a screen 13 and a speaker 14. A suitable output device is a tablet computer. The output device 12 in an embodiment has software thereon for receiving a signal representative of the pulse rate determined by the sensor output arid based on this pulse rate outputs an intervention appropriate to that pulse rate. Additional variables may be taken into account in this determination of the intervention such as identification of the user such that selection of the appropriate intervention by the software is made in part dependent upon the induvial user. This means that in addition to the pulse rate, the intervention output may be customised to a particular user. The pulse rate (and any other variables) are then processed using an appropriate algorithm to determine the intervention suitable for the user. The algorithm may in its simplest form compare the determined pulse rate to a look up table matching interventions to corresponding pulse rate ranges. The intervention is then selected corresponding to the pulse rate range that the determined pulse rate falls within.
It will be appreciated that processing of the pulses identified may be made by the output device instead of by the wearable sensor arrangement 2 meaning a signal representative of the sensor output is sent directly to the output device 12 prior to determination of the pulse rate and the output device 12 itself determines the pulse rate. It will also be appreciated that in the alternative the wearable sensor arrangement 2 may complete the determination step of determining the appropriate intervention and output a signal representative of the selected intervention to the output device 12.
It will be appreciated that it is beneficial to sense a user's pulse repeatedly and determine pulse rate at regular intervals during output of the intervention to the user. By obtaining such information the intervention may be altered to a different intervention, or the intervention itself may be modified. For example, in the event the intervention is music then the type or volume of music may be changed. Alternatively, the intervention may be changed from one type to another, or another intervention may be added. This could for example be delivery of an alternative game or task and may combine more than one intervention such as a game or task and music.
A further benefit of regular pulse rate monitoring whilst delivery of an intervention is clearly shown through the representation of Figure 2. The system (preferably the output device 12) receives regular pulse rate data indicated by arrow 16 and monitors the pulse rate. In the event of a predetermined change in the pulse rate (e.g. keeps rising for a predetermined time frame or a sudden rise in pulse rate for example) an output signal 18 is transmitted to a remote output device 20 such as a teacher's personal device. This output is emitted by the remote output device 20 and indicative of the predetermined change. The output could be an audible/visual alarm of any type to alert the teacher. This means the teacher is quickly aware that the normal intervention is not having the required effect and further assistance may be required. The predetermined change may as an example only be that the pulse rate keeps rising for a predetermined time frame or that there is a sudden rise in pulse rate.
A further benefit of determine pulse rate at regular intervals during output of the intervention to the user is the ability to provide an indication to the user of the trend of their pulse rate to be either increasing or decreasing. Such an indication may be in the form of a graphical representation such as an animation. For example, the animation may comprise an animal moving, standing, sitting, and lying down as the user's pulse rate decreases.
The intervention output by the output device comprises one or more of a visual output (e.g. instructional video such as yoga or breath control, calming sights, stories, games and/or tasks) and an audible output (story, music). It will be appreciated that both a visual and audible output may be provided concurrently. In more detail example of suitable interventions presented to the child at least in part determined by the pulse rate of the child are as follows: 1. Mandala Colouring -the child can select one of the templates and start colouring by selecting a colour and then the desired area.
2. Yoga Nidra Relaxation videos which the child follows.
3. Biofeedback Enhanced Music -multiple different pieces of music can be integrated which will be emitted reactive to the current heart rate of the child. Each piece of music can contain multiple tiers of music which relate to heart rate ranges.
Finger Tracing-the child follows the path into the middle of the labyrinth with their finger, leaving a trace, then reverses the journey and exits the labyrinth, erasing the trace with their finger.
5. Storytelling -videos of storytellers presented.
6. Nature videos -with calming sights and sounds from nature.
7. Breath control -the child follows these exercises on screen.
In use in a classroom environment, a teacher identifies if a child becomes stressed, angry, or emotionally overwhelmed, and the teacher will encourage the child to put on the wearable sensing arrangement and receive one or more of the interventions. The teacher can then visually monitor the child to check whether the visual stress level of the child is decreasing, and optionally in the event of the teacher having a remote output device 20 can be informed of the child's progress, particularly in the event that additional input is required.
Aspects of the present invention have been escribed by way of example only and it will be appreciated to the skilled addressee that modifications and variations may be made without departing from the scope of protection afforded by the appended claims
