NON-CONTACT TOUCHPAD APPARATUS AND METHOD FOR OPERATING THE SAME

摘要

A non-contact touchpad method uses an image sensor (10) to fetch an original image and adjust the original image to obtain an adjusted image. A motion image is detected in the adjusted image. The motion image is corresponded to a database (36) and divided into a plurality of division sections. At least one function block is defined in the database (36) and including at least one of the division sections. The database (36) defines the corresponding computer input action for the function blocks. The division section is determined to be a motion section or not according to a movement threshold. Finally, the computer input action is executed with reference to input functions associated with the motion section and defined in the database (36).
