Wireless controller with publicly-accessible communications link for controlling the content seen on large-screen systems

摘要

The present invention generally relates to a method and system for communicating signals between handheld wireless communications devices and large-screen projection systems, or large-screen display systems, or both, via one or more publicly-accessible communications link. The invention provides the means for such devices to serve as interactive controllers of screen-content which is projected, or otherwise displayed, on such screen systems. More specifically, the wireless devices are personal digital assistants (PDAs), cell phones and the like, each having finger or thumb-operated push-buttons, or rotatable dials, or touch-screen operations, or any combination thereof, from which control signals are initiated by a user and then communicated through one or more communications link such as: the international global network (Internet); or via wireless services provided by one or more telephony service providers; or via other radio wave transmission; or light wave transmission, such that the control signals cause desired interactive control of content on one or more of the screen-systems according to user input.
