The DataHand ergonomic keyboard
Reduces the range of finger motion. The finger tips move about 1/2" compared to the
conventional keyboards where the whole hand must move many inches. Wrist, arm, shoulder
and neck muscles become involved when working on a flat keyboard; on the DataHand
keyboard, only the fingers move.
¥ Reduces key activation forces. The fingers of DataHand operators use 20 grams of force
compared to 55 to 100 grams required on the flat keyboard. Research has shown forces below
48 grams reduce risks of musculoskeletal injury. Flat keyboard ÒbangersÓ often use forces 4 to
7 times higher than necessary.
¥ Provides optimal position and support for hands, wrists, and arms. The DataHand
design ensures correct pronation and relaxation of the hands, wrists, and arms.
