Patent ID: 8665840

Claim:
A receiving node for a wireless data network comprising: an antenna receive module that receives one or more data signals emitted from a transmitting node of the wireless data network; and a calculation module that calculates an orientation of the transmitting node in relation to an orientation of the receiving node, wherein said reception of said one or more data signals are based on magnetic induction, and said calculation of said orientation of said transmitting node is based on said one or more data signals, said one or more data signals comprise one or more preamble portions and said calculation of said orientation of said transmitting node is based on said one or more preamble portions, said wireless data network comprises a node that controls an output device, said receiving node further comprises a user interface module that provides, in cooperation with said transmitting node and said output device, a user interface functionality, whereby said provided user interface functionality is based on the calculated orientation of said transmitting node, the output device displays information on a two dimensional display surface, and said user interface module calculates a position on a two dimensional reference surface based on the calculated orientation of said transmitting node, whereby the position on said two dimensional reference surface corresponds to a position on said two dimensional display surface.
