HeadMouse: Arduino Based Computer Mouse for Disabled

Have you ever thought of controlling a computer with your head? I do.

A large population of the world suffers from many forms of physical disability. This community of people lack the major access of this modern resource: COMPUTER. Computers operate with human input through physical means that is required for response like the most important input required is used with keyboard and mouse using a hand. And these people lacking this ability hinders them from accessing the technology leading them to suffer.

 This project is a wearable computer aiding device that helps a person with physical disabilities to access a computer as a HID mouse. This mouse uses human head movement and breath input to mimic the features of a computer mouse hence makes the user access computer without use of hands. The mouse uses accelerometer and Sound sensor to capture our head movements and breath  inputs for mouse movement and clicks respectively. The sensors are fed into a simple low powered microcontroller that works  on the simple mathematical algorithms with out C Program to translate the motion into two dimension motion.

The design was developed as a headphone to be weared bt the user and operated. There are many devices in the market that offers this functionality but comes at very high extravagant cost. Our project has reduced the cost tremendously with offering the same powerful functionality.

The orignal prototype was developed my Nishanth Kumar from Coimbutore for Google Science Fair 2015. I further took and developed his idea to wireless functionality using Bluetooth.
