Abstract
Keypad indicia are integral with a window of a vehicle. The keypad indicia are formed using a ultra-violet (UV) fluorescent dye that is nearly invisible to a human eye until exposed to UV light. A UV light emitting device of the vehicle is configured for outputting UV light. The light emitting device is mounted for enabling the keypad indicia to be exposed to the outputted UV light thereby causing the keypad indicia to become readily visible by the human eye. An imaging device of the vehicle captures user interaction with the keypad indicia while the keypad indicia is exposed to the outputted UV light. The keypad interaction processor determines if a sequence of body part movements with respect to the keypad indicia that is captured by the imaging device during exposure of the keypad indicia to the outputted light corresponds to an access code of the vehicle.
