ABSTRACT:
A method of illuminating a computer keyboard, including: providing a keyboard with individually illuminatable keys; probabilistically determining the most likely key(s) that would be pressed next; illuminating the key(s) that are determined to be most likely pressed next while leaving keys probabilistically least likely to be pressed next unilluminated, an electronic dictionary is utilized to determine keys likely needed and the dictionary suggests keys based on running applications such that, if a calculator is running, numeric keys are illuminated and if a word processor is running, alphabet and related keys are illuminated; updating the electronic dictionary to include new words; disabling selective illumination when filling identification and password fields; providing disabling and enabling options; after time when none of the suggested keys have been pressed, automatically illuminating all keys; after additional time when none of all illuminated keys have been pressed, unilluminating all of the keys.
