Abstract

A key with three positions of actuation is described. The user can choose one of three possible finger locations to actuate the key to produce three unique outputs. Input options are increased without the need for additional keys. Complex keyboards are more difficult to touch type and large arrays of programmable keys must be visually searched, while smaller arrays give fewer input options. This device gives multiple entry options for each key and this reduces the number of keys required. The figure shows a keyboard button with a multiple position selection feature. The keytop 1 is similar to existing keytops with the additional (optional) feature of three concave sections 2, 3, 4 verifiable to the touch and sight of the user.
