HapticAid

Assistive Tech Band to ease
Heart Rate using Biofeedback

When one is anxious and the heart rate is over 90-95 the blood runs away from the skin’s surface. They start feeling tingly and feel numbness in their hands. One way a close one helps is by squeezing the hand slowly and periodically. HapticAid is a tool that mimics this, using haptic vibrations for independent anxiety/panic management.

The diagram shows two product sketches of the HapticAid Band which has a haptic driver, haptic motor, heart rate sensor, a display showing the heart rate and an on/off button
Product sketch of the HapticAid Band

It uses a haptic driver, a haptic motor, and a pulse sensor. When the pulse sensed raises beyond 90-95, the haptic motor vibrates at the rate of a normal heartbeat i.e. 75 beats per second on average.
