Bill Buxton's NotesThe Writehander is a twelve-button, one-hand chord keyboard. The one pictured here is the left-hand version. The four fingers sit on the four blue buttons in a row. The thumb pushes one of the other eight coloured buttons. The chords are the eight-bit ASCII code for the desired character, with the fingers defining the four low-order bits and the single thumb key pressed defining the four high-order bits.
