The SPACE bar may be shortened to provided room for these new keys.Īpplication is related to the subject matter described in Since there is now no mouse, the buttons or switches that are part of a regular mouse may be replicated as separate keys on the keyboard.
#LAPTOP OPERATION MOUSELESS CONTROL SOFTWARE#
These detected amounts corresponds to rotation of a mouse ball, and are sent to the computer's software to be treated as such. A comparison between a reference frame (previous image) and the current frame (present image) allows detection of the amount and direction of image motion. A sufficiently changed image is maintained as a new current image, which then itself changes, and so on. As the image "moves" within the movement sensor a portion of it disappears from the field of view, and is replaced with other image patterns. The digit is placed onto an end of a rod lens that either extends upward amongst the keys: say, proximate the junction of the "H", "J", "Y" and "U" keys or, horizontally outward from the front edge of the keyboard.
Motion of the digit produces motion of the image that is detected by a movement sensor and is translated into corresponding motion of the screen pointer. A mouseless, optical and position translation type screen pointer control images a portion of the texture or fingerprint on one of the user's digits, which may be a thumb or a finger.
