The Keyboard
One of the ways the Datahand helps to reduce RSI-related pain comes through requiring far less finger movement to type than do other keyboards. Each finger rests in a “well,” sort of akin to the “home row” on a traditional keyboard, except that the finger never has to leave its well. Each finger has five keys assigned to it, pressed by moving the finger north, south, east, west, or pushing down. Since a regular keyboard just uses one kind of finger motion (down) as opposed to Datahand’s five, the Datahand allows a greater variety of finger motions, reducing the repetition that can aggravate certain kinds of RSIs.
