Estimating the term…
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.
A keyboard comprising keys exhibiting a wave-like vertical profile along a width axis, a first set of keys at edges of the keyboard elevated relative to a second set of keys located in troughs at an expected location of rest of hands of a user on a home key row, the second set of keys separated by a third, elevated middle set of keys.
A method of designing a keyboard comprising:
A method of easing physical strain associated with typing, the method comprising providing a keyboard having keycaps exhibiting a wave-like vertical profile along a width axis.
A QWERTY keypad comprising keys whose top surfaces exhibit a continuous wave-like vertical profile conforming to a continuous smooth wave form along a width axis, a first set of keys at edges of the keypad elevated relative to a second set of keys located in troughs at “D” and “K” keys of the home key row, the second set of keys separated by a third, elevated middle set of keys, wherein a difference between a highest key and a lowest key is not greater than 5 mm and a vertical profile of the keys increases along a depth axis from a first row including a space bar keycap to a second row including a number keycap.
A method of designing a keyboard comprising:
