METHOD AND APPARATUS FOR ERGONOMIC KEYBOARD WITH WAVE-LIKE PROFILE

摘要

Keys of a keypad are configured to exhibit a wave-like vertical profile across a width of the keypad, thereby improving user comfort. Keys on the edge of the main grouping are raised, with the height of adjacent keys gradually reduced until a minimum (trough) is achieved. The height of the further adjacent keys is then increased until a maximum (peak) is achieved. In accordance with one embodiment, the keyboard includes two key troughs separated by an intervening raised key portion. The key troughs are positioned at the approximate location of hands resting on the home row of keys, for example in the case of a QWERTY keypad at the "D" key and at the "K" or "L" keys. The continuous, flowing change in the vertical profile of the keycaps renders the keyboard more accessible to the natural, relaxed state of the human hand, easing physical strain.
