Computer input device

An input device comprising:

• an upper frame, the upper frame configured to engage tactile mechanisms;
• and
• a backing comprising:
• an electronic display;
• and
• positional sensors interfacing the tactile mechanisms to detect operational positions thereof, wherein:
• the tactile mechanisms comprise a key-type tactile mechanism comprising a key moveably engaged by the frame between raised and depressed positions and wherein the key is transparent so that a symbol displayed by the electronic display is visible therethrough and wherein a first positional sensor of the positional sensors interfaces the key-type tactile mechanism to detect between the raised and depressed positions;
• the frame comprises a first magnet which attracts or repels a second magnet at the side of the key to bias an operational position of the key;
• wherein the first positional sensor detects magnetic field flux of the second magnet to determine the operational position of the key;
• and
• the first positional sensor is located beneath the electronic display.
