Abstract
The present invention relates to a method and system for displaying a video signal in dependence on a user interaction. The system comprises a display for receiving the video signal, at least one transmitter for transmitting location signals, and at least three transceivers for receiving the location signals from the transmitter and for transmitting modified location signals. The geometric locations of the at least three transceivers are known to a computing device. The computing device is then able to derive a transmit location of the location signals based on the received modified location signals, wherein the computing device is adapted to modify the content of the video signal in response to the derived transmit location in dependence on the user interaction.
