Inspired by the work of a certain Ken Yankelvitz, who happens to be a pioneer in constructing mouth-controlled joysticks and other kinds of adaptive devices, the QuadStick will hook up via USB, and will be 100% operated using mouth movements and sound alone. Comprising of a 3D-printed mouthpiece alongside the necessary slew of sensors which are able to recognize sips, puffs of air and lip position, you can use the QuadStick as a mouse and have it hook up to compatible voice-recognition software on a computer so that voice commands can be sent over to a PS3. Looks like the phrase “tongue action” would carry a whole new meaning now! Here’s hoping that the QuadStick would be able to meet its funding goal.
