About the Practice
Problem Statement:

Cost-effective self-stabilising smart handheld platform (spoon/pen) for elderly or Parkinsons’ disease-affected patients

Detail:

A smart platform (spoon/pen) for bringing stability to the hands of elderly people or patients affected with Parkinson’s disease, using the MEMS triaxial accelerometer. It introduces an easy-to-adopt hand mount device that can be used to support the tremors in the hands of elderly people or in persons affected with the said disease. The support would help in day-to-day activities like writing, having food with a spoon and also holding crockery/knives. The designed system is built around an 8-bit AVR microcontroller, along with a 6-DOF (degree of freedom) tri-axis IMU (inertial measurement unit) in the form of hand-held hardware. The person’s hand movements are read by the system in the form of acceleration data which is then fetched from the IMU and is made to go through an embedded Kalman filter that performs estimation on the data acquired. A custom-designed electromagnetic (a servo) drive is designed to work with an embedded microcontroller-based application. Every time there is a change in acceleration data, the servo is actuated in a direction opposite to the recorded value from the person’s hand movement. This device uses six point-based sensor data calibration to eliminate discrepancies in output due to zero-G and installation errors
