Project:  Wearable wrist-movement-health sensing device for avoiding Carpal Tunnel Syndrome.

Listen to your wrist is a low cost, easily configurable device which measures, records and analyzes the angular movement of your wrist so that repetitive stress injuries such as carpal tunnel syndrome can be avoided. It is a wrist posture correction device which utilizes vibrotactile feedback with music to convey (alarm) information about wrist health to the body.  ​

The motion of wrist (angles in four directions) are represented in easy to understand interactive graph. The user can see both the live data as well as the history of wrist health. This makes the discussion of disability easier and less ambiguous as the user can keep track of improvement or deterioration in their wrist health.  

Repetitive wrist strain injuries are one of the nation’s most common occupational health problems, costing businesses $2.8 billion annually according to the 2003 Liberty Mutual Workplace Safety Index. Many repetitive strain injuries stem from the use of conventional computer keyboards, mice, musical instruments etc.

Wearable Glove to record the wrist health data:

​"Listen to your wrist" is a light, fashionable and wireless glove that can be worn without hindering work such as typing or, playing a musical instrument. Under the hood it is fitted with flex sensors, bluetooth, micro controller  (Arduino) and vibration motors. The flex sensors measure the degrees of wrist bend in four directions (Flexion, Extension & Radial and Ulnar deviation).

The data is relayed to a computer using bluetooth. The vibration motors provide the vibrotactile feedback to the user so that she can correct her wrist posture or, take a break from work.

Data Representation in Processing (Java based visualization tool):​

​The video on the left shows the various ways the wrist data can be visualized and understood by the user. She can chose to monitor a live stream of data or, look at long history (either in a clock dial or bar graph) to better understand her habits.
