Abstract
An apparatus and method are described herein, which simultaneously promotes a positive computing experience for users of portable computer systems and increases overall durability and longevity thereof. In one embodiment, an optical apparatus enhances the user computing experience, in one embodiment by simplifying operation, and is much more durable and long-lasting than mechanical switch and dial type devices it may replace. In one embodiment, the present invention is directed to an apparatus, which enables efficient portable computer device function, field, and data selection, gaming, input, interconnection, and other switching-related functions, simplifying operation and enhancing versatility thereof, yet without exposing the portable computer interior to any degree to incursion of environmental contamination. In one embodiment, an optical apparatus obviates openings in a portable computer package which would otherwise be required. In one embodiment, the apparatus, capable of sensing manipulation and directed by software, has a light source and corresponding light sensor.
