Patent ID: 8150455

Claim:
A mobile communication device, comprising: a motion sensor; a transceiver configured for long-range communication; a short-range wireless communication module; and a processing unit configured to operate in conjunction with the short-range wireless communication module and further configured to: determine whether the mobile communication device is to operate in a desktop mode or a projector mode; when in the desktop mode: establish via the short-range wireless communication module a communication link with a selected remote host device having a display screen adapted to visualize a cursor, convert amounts of displacement of the mobile communication device in a first direction and a second direction detected via the motion sensor into displacement data of the cursor in a two-dimensional coordinate format compatible with the display screen of the remote host device, and transmit via the short-range wireless communication module the displacement data to the remote host device; and when in the projector mode: establish via the short-range wireless communication module a communication link with a selected remote host device having a display screen adapted to visualize a cursor and coupled to a projector that projects images from the display screen to a vertical board, convert amounts of displacement of the mobile communication device detected in the first direction and a third direction via the motion sensor into displacement data of the cursor in the coordinate format compatible with the display screen of the remote host device, and transmit via the short-range wireless communication module the displacement data to the remote host device.
