User-aware video display

Abstract

The present invention provides methods and systems for displaying a video signal depending upon a user interaction. An example system includes 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 depending upon the user interaction.
