I wanted to test the idea of using the tongue to control a computer. The most obvious way would be to map x/y coordinates in a Windows-style UI with tongue movements constrained to a plane. This doesn’t work terribly well, as even though the tongue has fine motor control, it’s very difficult to smoothy achieve the 2D movements needed to operate a system that has been developed around a classic mouse. I think there is possible applications for swipe interfaces, carousel menus, yes/no input, etc.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
