Abstract
A hand-held computing device including a pair of grouped buttons disposed in a pattern including at least one row, such that each input device in each row is substantially equidistant from a location or point unique to each group is used to optimize the use of the user'"'"'s thumbs for data input. The use of the thumb is the most powerful digit on the hand and has the greatest range of motion. Using only the thumbs to actuate the buttons of computing device such as a calculator, allows the hand to remain less obtrusive to the accessing the buttons, therefore less prone to input errors. In addition, by maintaining the relative position of the rest of the hand at a consistent location on the housing, the user'"'"'s proprioceptive and kinesthetic senses allow the user to learn and consistently locate keys. Upon this learning, the user would be able to input data without visual cues further increasing efficiency with a short learning curve.
