The DataHand ergonomic keyboard offers a total of 132 keys (more than even extended flat keyboards) through the use of five keyswitches clustered around the tips of each of the fingers. With four modes, shifted by the thumbs, hand movement is no longer required to perform keyboard work. Hand support results in the elimination of the major source of musculoskeletal stress in hands, wrists, arms, shoulders, backs, and necks.
DataHand keyboard users are no longer forced to conform to an arbitrary, stressful, and contorting keyboard design. As user testimonials make clear, the DataHand keyboard is the most ergonomically efficient keyboard and mouse alternative on the market.
Dramatically different in appearance from the traditional flat keyboard, the DataHand ergonomic keyboard incorporates unique finger and thumb switch modules within two contoured hand rests.The DataHand ergonomic keyboard naturally cradles the hands of a user, completely supporting both the hands and arms.
Innovative DataHand key modules wrap the keys three dimensionally around the tips of the fingers to offer unique ergonomic and productivity benefits. Five keys are placed directly north, south, east, west, and directly below the tip of each finger. Six keyswitches are placed around the thumb. Two of these are below each thumb. The thumb down switches are two stage switches with the second stage serving as a mode lock. The first level shifts into the mode temporarily, and second level of the switch locks the mode until the switch is touched again to release it.
The DataHand ergonomic keyboard makes use of natural finger movement capability while maintaining the traditional QWERTY key layout (or for those who prefer it, the Dvorak key layout can also be chosen). The thumbs are used to shift between the three primary modes: Normal (alphabetical), Numbers and Symbols (placing the numbers on the Home row), and the Function and Mouse Mode (which places mouse control at the tip of the index fingers). A Ten Key Mode allows single-handed numeric entry.
In addition to Mode Shifting, the thumb operates the Return, Tab, Space, Backspace, Cap Shift, Control (on Command), Alt (or Option) keys. Much time is saved by having these functions in close proximity to the thumbs.
The DataHand ergonomic keyboard dramatically reduces both variables of the work formula—force and distance. By placing the keys in close proximity to the fingers, finger travel distance is greatly reduced. Key activation forces are also reduced by 50 percent or more, and operating speed is improved.
