20100053082 | REMOTE CONTROLS FOR ELECTRONIC DISPLAY BOARD - Techniques for interacting with an electronic display board are disclosed. According to one embodiment, a remote controller includes a laser generator, several motion sensors, a Micro Central Unit has data process capability and memory inside to store programs and a transceiver or a transmitter. A laser beam from the laser generator facilitates a writing movement on the electronic data board, the motion sensors detect the movement of the remote controller, and the MCU calculate the sensor data to derive the movement, the transmitter transmits the movement from the controller to the electronic data board. In accordance of the detected movement, the movement of the remote controller corresponding to the laser is electronically represented on the electronic display board. | 03-04-2010 |
