Embodiment Construction

[0034] figure 1 A block diagram of a first embodiment of the system according to the invention is shown. The system includes a pointing device 10 and an appliance 20 . The pointing device may be part of a conventional remote control including keys (not shown) for controlling functions of the appliance. However, preferably the pointing device is a completely novel device comprising only a single key or pair of keys for controlling the appliance. The appliance may be a television on which the PC-based application can be viewed. Interface with PC-based applications via a freely moving cursor. Move the cursor on the screen by moving the pointing device.

[0035] The television set has on each of its four sides a light source 30, preferably a light emitting diode emitting infrared light. with a unique frequency f x1 , f x2 , f x3 , f x4 Modulates each LED. Therefore, the four sides of the TV are associated with unique frequency modulations.

Abstract

A system is disclosed comprising a pointing device (10), an appliance (20) and at least two light sources (30), which are either part of the appliance (20) or which are positioned in its vicinity. The pointing device (10) comprises a light detector (12) for detecting light signals from the at least two light sources (30). The system further comprises measuring means (14) for measuring a property of the detected light signals, representative of the aiming point of the pointing device (10). The system can be used for controlling a free moving cursor on the screen of the appliance (20). Alternatively, it can be used for controlling other appliances by movement or gesture of the pointing device.

Description

technical field [0001] The present invention relates generally to remote control pointing technology, and more particularly to a system for controlling an appliance based on an aiming point of a pointing device relative to the appliance. [0002] The invention also relates to a pointing device and implement for such a system. [0003] The invention further relates to a method for controlling an appliance based on an aiming point of a pointing device relative to the appliance. Background technique [0004] Typically the use of a computer mouse is very common and acceptable for easy interaction between a user and point-and-click actions on interactive content. Typically, these operations are performed near the screen and require a flat surface or equipment that is either difficult to use or very expensive. [0005] On the other hand, for lean back and relax applications, such as watching videos and listening to music, a remote control (RC) is commonly used. It can also be o...
