DETAILED DESCRIPTION OF EMBODIMENTS
[0019] Reference will now be made in detail to the various embodiments of the disclosure, one or more examples of which are illustrated in the figures. Within the following description of the drawings, the same reference numbers refer to the same components. Generally, only the differences with respect to individual embodiments are described. Each example is provided by way of explanation of the disclosure and is not meant as a limitation of the disclosure. Further, features illustrated or described as part of one embodiment can be used on or in conjunction with other embodiments to yield yet a further embodiment. It is intended that the description includes such modifications and variations.
[0020] Common smartboards can be controlled with a remote controller. These remote controllers often work based on the IR standard. Smartboards have an externally installed module that corresponds to the IR signals transmitted by the remote controller to execute the command that is given via the remote controller. This external module is only able to receive the IR signals transmitted by the remote controller if the remote controller is pointed at the module in a certain angle, thus a rapid and effective use of smartboards not possible. Moreover, these externally installed modules result in extra cost in production and use, thereby diminishing the attractiveness of the use of smartboards.
[0021] The embodiments of the present disclosure overcome the above drawbacks by providing a system with a plurality of transmitters and receivers such that the remote controller can be pointed anywhere at the screen of the smartboard and the signals transmitted by the remote controller are recognized wherever the remote controller is pointed, without the need for an externally installed module. Thereby a rapid and effective response and use of the smartboard is guaranteed and costs are reduced.

The number of LEDs 113 and photodetectors 114 may be equal or differ. The LEDs 113 and photodetectors 114 may be of different sizes such that one or more photodetectors 114 correspond to the light emitted by one LED 113 or vice versa.

In another example the controller unit 12 is configured to perform the function of the application 50.
[0035] The camera 60 is configured to provide information indicative of the location of the remote controller 20 to the application 60 and/or controller unit 12. The transmission of the information may occur by means with or without a wire and the processor to process the information indicative of the location of the remote controller 20 may be part of the camera 60 or an external module.
