Here’s a keyboard-glove prototype in development by Jeff Rowberg. The Keyglove is a glove-based USB input device that provides full keyboard control, designed for wearable and mobile computing and to assist the disabled.
According to Jeff:
The Keyglove is a portable Arduino/AVR-powered glove that uses touch combinations (for keys) and an accelerometer (for the mouse) to generate keyboard and mouse control codes using only one hand. Once learned, the glove can easily be used without looking, making it perfect for embedded/wearable environments. The glove is thin and light, built to allow other activities (such as writing) without being in the way. The current design also incorporates Bluetooth wireless connectivity, a rechargeable lithium polymer battery, simple vibration feedback, audio feedback, and a tri-color status indicator LED.
