How are DataHand finger motions less repetitive?

On other keyboards, each key requires a repetitive downward keystroke. All keys require the same downward, percussive finger movements for activation. On the DataHand keyboard, only one of the five keys surrounding each finger requires a downward key activation movement. The other four keys surrounding the fingertips require movements to the north, south, east, and west. In this way, the DataHand keyboard distributes typing motions in five tactually distinct directions. Rather than repeating the same undifferentiated downward, percussive motion, the different keys surrounding each finger become associated with five different, much more gentle, shorter, less stress inducing movements. In addition, on the flat keyboard and other keyboards based on the basic flat keyboard paradigm, workers tend to use more force than necessary to activate the keys. This tendency compounds and intensifies repetitive motion aggravations. On the DataHand keyboard, the tendency to use excessive force is elimi
