LipSync, a mouth controlled input device, which will enable people with little or no hand movement to operate a touchscreen device.

The Lipsync is a mouth operated joystick that allows a person to control a computer cursor with a minimal head and neck movement. All the electronics are housed in the ‘head’ of the device so there are no additional control boxes, making the LipSync a good candidate for portable, wheelchair-mounted applications. The mouthpiece is attached to a precision miniature joystick sensor that requires only a very slight pressure on the shaft in order to move a cursor on the screen. The mouthpiece is hollow and allows a person to perform left and right mouse button clicks by alternatively puffing or sipping into the tube.

The "LipSync" is an assistive technology device which is being developed to allow quadriplegics and other people with limited hand use the ability to use touchscreen mobile devices by manipulation of a mouth-operated joystick with integrated sip and puff controls. It is open-source, to make the Lipsync a solution that can be made at the community level for less than $300.
