Head-Controlled Computer Mouse by LEADer Shadab

LEADer Shadab from NTTF College Belur invented the "Head Mouse". Shadab reasoned that some people with developmental and locomotive disabilities cannot use their hands to operate a computer mouse. In this project, he developed a hands-free computer mouse that moves the cursor according to the movement of our head.

The clicks and double clicks are obtained by breadth inputs. It uses an accelerometer and gyroscope fixed in the mouse to track the movement of the users head with I2C communication. This data is then used by a onboard micro-controller to analyze the motion of the user. This then communicates the computer-wired (bluetooth)/ wirelessly (user preference) and moves the cursor via serial communication. The mouse uses a microphone to get users breath inputs in the form of blows to analyses the breath to be left click, right click, double click or scroll. The mouse then sends the cursor and click data to computer either via Bluetooth or via USB Cable.

Scientifically, head movements have 6 degrees of freedom. An accelerometer cannot alone track all the 6 degrees of freedom, but only is limited to 4 degrees of freedom. Coupling a gyroscope with it adds another 2 Degree of freedom. This realization overcame one of the major challenges Shadab faced in designing the head mouse.

While this project is still in developmental phase, it is a great example of combining skills learned in college with a social project that could have a big impact in the lives of others.
