No beacons 41 and 42 are, for example, noise sources, such as lamps, reflection, sunlight and so on. D.

FIG. 2 schematically shows the remote control device 10 and the device 20. The device 10 comprises a remote control unit 1 and the camera 11. The camera 11 is connected to the controller 12. On the one hand controller 12 connected to the transmitter 13 on the other side of the controller 12 is connected to the processor unit 1 2 . The processor 2 is connected to the memory device 1. The transmitter 3 sends to the receiver 13, the control data 21 associated with device 20 to control unit 20. The camera 11 detects the light points on the display in the time interval, the points of light generated from the beacons 31 and 32 and no beacons 41 and 42 as shown in FIG. 3-5. Exchange of control data is usually performed by means of wireless technology, for example by an RF signal or other wireless signals.

Alternatively, the device 1 may be part of the controller 12, or vice versa. Alternatively, the device 1 may take the place of the controller 12 or the device 1 may be positioned between the controller 12 and transmitter 13. Receiver 21 could alternatively be part of device 20, etc.

Also, as shown in FIG. 3-5, the camera 11 detects the first and / or second light points 51 and / or 52 are formed from the beacons 31 and / or 32, and detects the third and / or fourth light points 61 and / or 62 is not formed from beacons 41 and / 2 or 42. The processor evaluates the at least one feature in response to control information obtained by detecting light spots 51, 52, 61 and / or 62. This feature must be sent to control unit 20 as control data, or to be converted to control data to control device 20.

The camera 11 is preferably configured to detect the first and / or second light spots 51 and 52 over a time interval, and the third and / or fourth light points 61 and 62 over a time interval. The information comprises the first and / or second information obtained by the first and / or second detection of the first and / or second light spots 51 and 52 over a time interval, and the third and / or fourth information obtained as a result of the third and / or fourth detections third and / or fourth light points 61 and 62 over a time interval. The memory unit 3 stores the time interval for the first and / or second information and the third and / or fourth information.

To be able to distinguish light coming from the lighthouse 31-32, on the one hand, and 41-42 beacon, on the other hand, the camera 11 may be, for example, adapted to detect the frequency or wavelength or brightness, or on / off mode etc. modulated light from the lighthouse 31-32 and / or, for example, the camera 11 can be configured to detect feature differently modulated or unmodulated light beam from a lighthouse not 41-42. Detecting the frequency and wavelength and brightness and on / off mode, etc. It is conventional in the art. Furthermore, to detect the on / off mode, it may be necessary to choose the duration of the time interval greater than the period of the on / off mode, and / or it may be necessary to select between the on / off shorter than the duration of the time interval, and / or additional time (if any) between two successive time intervals may be necessary to select properly when compared with the period of the on / off mode, and / or it may be necessary to choose between the on / off properly compared with the extra time (if any) between two consecutive time intervals, and / or it may be necessary to use several time slots, etc. These detection processes may alternatively be partially or completely transferred to chamber 11 by the controller 12 and / or the device 1.

FIG. 3 shows the first display chamber 11 by the remote control device 10 for the two different time intervals. In this case, no beacon 32 and beacon 42, such as closed or not present all the time. In the first time slot or at the first time creates the display chamber 11 containing the light 51 from a beacon the point 31 and point 61 on the light beacon 41. In the second time slot or time into the second chamber 11 creates a map containing a point of light from the lighthouse 61 41, just because the light spot 51 from a beacon 31 temporarily can not be detected, as indicated by the dotted line. However, by using information from both maps, a new light point position 51 may be calculated, here for example, under the assumption that no rotation does not take place. Clearly, the user, compared with the first time interval, induces slightly more to the left in the second time interval because the light points 51 and 61 are located a little more to the right.

FIG. 4 shows the second display 11 by the camera remote control device 10 for the two different time intervals. In this case, no beacon 42, for example, is not present or is closed all the time. In the first time interval or at a first time chamber 11 creates a map containing a point of light 51 from a beacon 31, a point of light 52 from a beacon 32 and point of light 61 from a beacon 41. In the second time interval or at a second time chamber 11 creates a display, comprising a point of light 52 from a beacon 32 and the point of light from the lighthouse 61 41 only by the fact that the light spot 51 from a beacon 31 is temporarily not detected, as indicated by the dotted line.

However, using both the information maps can be calculated new position of the light point 51. It is clear that the user, compared with the first time interval, induces slightly lower in the second time slot due to the fact that the light points 51, 52 and 61 are arranged a bit higher.

FIG. 5 shows the third display chamber 11 by the remote control device 10 for the two different time intervals. In the first time slot or at the first time creates the display chamber 11 containing the light 51 from a beacon the point 31, a point of light 52 from a beacon 32, 61 bright point from the beacon light 41 and a point 62 on the beacon 42. In the second time slot, or second time camera 11 creates an image comprising a point of light 52 from a beacon 32, 61 bright point from the beacon light 41 and the point 62 of the lighthouse 42 only by the fact that the light spot 51 from a beacon 31 is temporarily not detected, as indicated by the dotted line. However, using both information display, the new position of the light point 51 can be calculated. Clearly, the user, compared with the first time interval, second time interval suggests slightly higher due to the fact that the light points 51, 52, 61 and 62 are located slightly lower. Here, to assess the lack of light in terms of location affine transformation can be used.

Preferably, the processor 3 is adapted to improve the assessment of at least one control feature in response to the first, second, third and fourth information for a second time interval and / or the first, second, third and fourth information for a first time interval. It is clear that when more information is available than is absolutely necessary, the information can be checked on the irregularity and the evaluation can be improved.

Looking at the display, obtained at various time intervals, transformation gates corners, angles, scaling, offset, etc. It can be determined and destination can be checked and / or adjusted. With a large number of maps, time intervals and light points should not make one exception. The time interval can be of any length and may contain one moment in time, or more than one point in time. Between two successive time intervals may or may not be present extra time.

Usually light point will cover more than one pixel. If light point shape or brightness of the light points are not completely symmetrical, for each point of light can be determined by the angle of rotation, comparing both mappings. If the shape and brightness of the light point light point perfectly symmetrical, the two or more light points required to determine the angle of rotation, comparing both mappings. The light points may also be known as a spot. These spots may comprise coordinate data, size and brightness information.

system user interface, such as a control system based on gestures, or pointers, the remote control device comprises a camera, such as a pointer device on the basis of the camera and a device such as the target device, and beacon such as a fixed beacon. Beacon may include, for example, infrared illumination LEDs. These spots of eight spots can be sent to an apparatus that can process the data spots and the processing result used to control the device, for example, adapting the graphical user interface on a display screen. To be able to reliably detect spots by any other noise sources, the spots detected by a camera to be monitored by the frame so that, for example, their brightness modulation could be correlated in time and checked against known beacon modulation. Beacons may further have a certain distance between them and / or known location with respect to each other and / or relative to the device. Using the display spotted in neighboring frames can be assessed the situation of missing closed obstacle spots. More reliable tracking beacons can be achieved using patches from one or more sources of noise.

Fig. 6 differs from FIG. 2 in that the apparatus is moved from one remote control device 10 to device 20. Further, the beacons 31 and 32 and 21 are part of a receiver device 20, which further comprises a screen 22 is connected to a controller 23 which is connected to the receiver 21 and processor device 3 1. In this case, a transmitter 13 will send data to the receiver display 21 to control unit 20. In addition, in or near the device 20, display data must be processed, as discussed for FIG. 2-5.

Alternatively, the device 1 may be part of the controller 23 or vice versa. Alternatively, the device 1 may take the place of the controller 23 or the device 1 may be positioned between the controller 23 and the receiver 21, etc.

Alternatively, the device 1 may be disposed outside the remote control device 10 and / or outside the device 20 and be configured to communicate via a wired or wireless communication with the remote control device 10 and / or 20 unit.

To summarize, the device 1 estimates signs control device 10 a remote control comprising a camera 11 for detecting the light spots 51, 52 from the beacons 31, 32, located in or near the device 20 to be controlled by a device 10 remote control by allowing the cameras 11 further detect light points 61, 62 from non beacons 41, 42. The CPU 2 controls evaluated characteristics in response to information obtained from the detected light spots 51, 52, 61, 62. not beacons 41, 42 contain sources of noise, or any other sources different from the beacons 31, 32. The storage devices 3 remain for the time interval of the information obtained for detection. Light coming from the beacons 31, 32 can be modulated, and the light coming from the non beacons 41, 42 may be other light. The information may contain coordinates, size and brightness of light points 51, 52, 61, 62, and for detecting received during the time interval.
