1. A user interaction system, comprising:
- an electrical apparatus;
a portable pointing device operable by a user for pointing to a region in space;
a camera taking a picture, which camera is physically attached to the pointing device so that in operation it images the region pointed to without imaging the pointing device;
a distributed digital signal processor, the digital signal processor being capable of receiving and processing the picture, and capable of transmitting user interface information derived from the picture to the electrical apparatus;
at least one localization beacon that can emit electromagnetic radiation for use by the digital signal processor in order to recognize where the pointing device is pointing;
wherein the digital signal processor estimates a motion or a motion trajectory of the pointing device; and
,wherein said digital signal processor recognizes where the pointing device is pointing without imaging any electromagnetic radiation emitted from the pointing device itself.

Abstract
The user interaction system comprises a portable pointing device (101) connected to a camera (102) and sending pictures to a digital signal processor (120), capable of recognizing an object (130) and a command given by the user (100) by moving the pointing device (101) in a specific way, and controlling an electrical apparatus (110) on the basis of this recognition.

18. A method of interacting between an electrical apparatus and a portable pointing device, the device being physically attached to a camera, the method comprising:
-
pointing the pointing device to a region in space; taking a picture with the camera, wherein the picture is of the region pointed to, and wherein the picture does not contain any image of the pointing device; receiving and processing the picture; receiving electromagnetic radiation from at least one localization beacon; recognizing where the pointing device is pointing by at least in part on utilizing the received electromagnetic radiation; transmitting user interface information derived from the picture to the electrical apparatus; wherein the processing step comprises estimating a motion or a motion trajectory of the pointing device; and
,wherein the recognizing step does not image utilize any electromagnetic radiation emitted from the pointing device itself. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26)

27. User interaction system, comprising:
-
an electrical apparatus; a portable pointing device operable by a user for pointing to a region in space; a camera taking a picture, which camera is physically attached to the pointing device so that in operation it images the region pointed to without imaging the pointing device; a distributed digital signal processor, the digital signal processor being capable of receiving and processing the picture, and capable of transmitting user interface information derived from the picture to the electrical apparatus; at least one localization beacon that can emit electromagnetic radiation for use by the digital signal processor in order to recognize where the pointing device is pointing; wherein the digital signal processor estimates a motion or a motion trajectory of the pointing device; and
,wherein said digital signal processor recognizes where the pointing device is pointing without utilizing any electromagnetic radiation emitted from the pointing device itself, except for transmitting user interface information to the electrical apparatus.
