Abstract
A multi-touch system is provided. The multi-touch system includes a multi-touch detection area generated by a mobile device and a first communication device, the mobile device and first or second communication device being movable relative to each other. The mobile device is operable to determine a first set of coordinates for a first detectable object within the multi-touch detection area as a function of: a distance between the mobile device and the first communication device, a distance between the mobile device and first detectable object, and a distance between the first communication device and first detectable object.
