Overview of the Design
Low - cost, mouth operated computer mouse for people with limited mobility!
We created a fully functional assistive device mouse target towards people with little or no movement in their arms or legs. We used a common joystick, a pressure sensor, and an Arduino to build it (under 40$).
The mouse pointer is controlled by a tube glued to a joystick that the user would control with their mouth. To right click and left click you would blow or suck on the tube and using the keyboard was made using built in voice commands to the Mac OS. Activating voice commands took a quick double puff before it would go into voice command mode. Scrolling was faciliated by a special double suck command.
