A smart glove that helps people with posttraumatic stress disorder (PTSD)
Grippy is inspired by the notion of partnership in Human-Computer Interaction and the practice of exposure therapy in Cognitive Behavioral Therapy (CBT). Grippy senses changes on one’s heart rate and reminds him or her to check on and report self-perceived stress.
Data gathered from grippy's internal sensor used to generate an annotated map (on a smartphone application) indicating one’s daily stressfull situation & it's locations in real time. When sensing the person getting nearby one of these locations, Grippy encourages the person to go on a exposure self-training there following guided smoothing vibration patterns and provide support of relief.
Internal Hardware Design Prototyping
Grippy uses various sensors and bluetooth embeded on a custom arduino board to function:
1) Heart Rate Sensor: Measure the heartrate from user's wrist
2) IMU Sensor: Measure the movement and count user's walking stpes
3) Vibration Motor: Trigger differnet smoothing vibration patterns according to different scenario
3) Presuuer Sensor: Report level (1:Low, 2: Medium, 3:High) of stress during the moment
4) Bluetooth: Communicate with mobile application and transmist the data or receive the command for next action
Software System Diagram
The software behind the grippy was developd using C++ language. It follows traditional finite state machine approach to achive the desired user experience while usin grippy.
