Abstract
A touch type keyboard with an array of mechanical keys. Each key has a plurality of capacitive sensors to detect a finger's location on the surface of the key. The array provides single strike access to an entire alphabet, while reducing hand motion. The invention overcomes previous conflicts, to combine wide finger-spacing with closer reach to each character. One embodiment also includes cursor control functions embedded within the home row, and layered labeling to improve visual simplicity.
