ABSTRACT:
A novel ergonomic keyboard provides improved user comfort while maintaining a configuration sufficiently close to conventional keyboards to minimize the need for retraining of experienced keyboard users. The novel keyboard is arcuate, with central keys situated closer to the user, and sloped in two directions, with keys sloping up toward the center and sloping up away from the user's position.
