Abstract: A multi-directional remote control system and method is adapted for use with an entertainment system of a type including a display such as a monitor or TV and having display functions employing a mouse type control. The remote controller may be conveniently held in one hand of a user and still provides full mouse type functionality. The remote control system and method images the screen of the TV or other display to detect relative motion between the controller and screen. This position information is transmitted to the entertainment system for control of a cursor or other GUI interface.

Abstract: A remote control method and system employ remote controller (10) which is adapted for use with an entertainment system of a type including a display (222) as well as providing functions such as Internet access or other functions requiring a keyboard and/or a mouse. The remote controller includes a folding housing and may be operated in a closed or opened configuration. A first set of control inputs (12) are provided on the outer surface of the housing. The housing may be opened, thereby doubling the surface area of the remote controller, to expose a keyboard (56). One or more wireless transmitters are operable with the housing in either of two configurations oriented at 90 degrees to each other and controlled by the first set of control inputs and the keyboard. The remote controller may be conveniently held in one hand of a user when in the folded or closed position and conveniently rested on the lap of the user or a support surface when in the opened position and used as a keyboard.

Abstract: A wireless keyboard and reader combination comprises a keyboard having a plurality of keys, an antenna, and a plurality of passive transponder circuits, employing backscatter transmission coded in the time domain using a reflected series of pulses, coupled to the antenna and associated with the keys. For example, SAW transponders may be employed. The passive transponder circuits are selectively coupled to the antenna and provide a coded response identifying a key in response to key activation. An associated reader includes a source of an interrogating field applied to the antenna of the keyboard and a decoder for determining the coded response from the passive transponder circuits.
