Remote controls for electronic display board
First Claim
1. A system for use with a base computing device, the apparatus comprising:
- a transparent panel; and
a controller comprising;
an enclosure;
at least a key disposed on one side of the enclosure to be accessed by a user using the controller;
a laser generator, housed inside the enclosure, coupled to and controlled by the key to project a visible laser for a user to use the controller as a remote pen to write a letter, a word or draw a line through the transparent panel onto a presentation being displayed on an electronic display board, wherein the transparent panel being held by the user between the controller and the electronic display board allows the user to write while moving around;
a plurality of motion sensors generating sensor data when the controller is moved by the user against the transparent panel;
a micro control unit coupled to the motion sensors and configured to derive a movement from the sensor data after a calibration is done with the controller, wherein the calibration is performed with the visible laser pointing at two or more designated points respectively displayed on the electronic display board, and wherein as the visible laser moves from one of the points to another one of the points, the sensor data is compared with motion of the visible laser, an offset therebetween is considered when the movement of the controller is derived; and
means for transmitting the movement wirelessly to the base computing device configured to present on the electronic display board a symbol according to the derived movement of the controller, wherein the transmitting means is coupled to the micro control unit, the symbol is not part of the presentation but is superimposed onto the presentation.

Abstract
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.

11. A method for interacting with an electronic display board, the method comprising:
-
generating a laser beam from a controller towards a portion of a presentation being displayed on the electronic display board; trespassing the laser beam through a transparent panel being held by a user between the controller and the electronic display board, producing sensor data from the controller including a set of motion sensors when the user uses the controller to write against the transparent panel regardless where the user moves, after the laser beam is used to calibrate the controller by pointing the laser beam at two or more designated points respectively displayed on the electronic display board, wherein as the laser beam moves from one of the points to another one of the points, the sensor data is compared with motion of the laser beam, an offset therebetween is considered when the movement of the controller is derived; and transmitting the sensor data wirelessly to a base computing device to determine the movement of the controller, wherein the base computing device is configured to generate a symbol according to the derived movement of the controller and superimpose the symbol onto the presentation. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
