Wireless Need Sharing & Home Appliance Control For Quadriplegic Patients Using Head Motion Detection Via 3-Axis Accelerometer

Abstract

A person experiencing quadriplegia has paralysis affecting every limb and part of their body starting from the neck down. These individuals frequently have trouble speaking loudly and are unable to move. They are consequently unable to communicate their needs to other family members who are occupied at home right away. Furthermore, they are unable to manage their own room’s lights or fans without assistance from others. In this research, an embedded system is developed that enables bedridden quadriplegic individuals to easily communicate their needs to family members and to operate appliances like fans and lights on their own without the assistance of others. Fortunately, the quadriplegic person can move his or her head. This developed system uses an accelerometer sensor to record head movements. After that, the system analyzes the head movement data to determine whether the quadriplegic patient shared any need to serve or command for operating household equipment. In cases of need, it is transmitted via Bluetooth to another device that is kept in a common place in the home close to other members and notifies the needs on a matrix display. For the commands of appliance control, the system takes steps to switch the light or fan according to the desires of the patient. The system also has the option to measure the pulse rate and oxygen saturation of the patient. A working prototype of the system has been developed and tested. It made quadriplegic people' life much easier and considerably more comfortable.
