The present invention discloses a remote controllable video display system and a controller therefor, wherein positional information is generated by a sensor according to light from a light source. The controller includes a button with a predetermined function, wherein when the button is pressed or released, the status of the button (pressed or released) is outputted but (i) the positional information is not outputted or not processed within a predetermined period of time; or (ii) the positional information is not outputted or not processed when the remote controller has an acceleration larger than a predetermined value. Or, when the button is pressed once, the controller outputs double-click or multiple-click action information.

Remote controllable video display system and controller and method therefor

The present invention discloses an optical touch control apparatus, comprising: a light guide module having an optical information capturing position, the light guide module guiding light to the optical information capturing position, and generating optical information according to light input through or reflected from the optical information capturing position; and an image sensor module for sensing the optical information, and generating an electronic signal according to the optical information.

Optical touch control apparatus and method thereof

A method for increasing a report rate of a wireless mouse for decreasing delay time of the wireless mouse includes selecting a packet mode, inputting data corresponding to the selected packet mode according to control signals inputted into the wireless mouse, performing a first error check operation according to a first data, performing a second error check operation according to the first error check operation and the inputted data, forming an error check block according to the second error check operation, forming a packet according to the error check block and the inputted data, and outputting the packet through a radio-frequency channel.

Method and related wireless mouse for decreasing delay time of data packet transmission system

The present invention provides a method for increasing a report rate of a wireless mouse for decreasing delay time of the wireless mouse, which includes: selecting a packet mode from a plurality of packet modes and inputting data corresponding to the selected packet mode for forming a packet according to control signals inputted into the wireless mouse; and outputting the packet through a radio-frequency channel. The present invention further provides a method for reducing power consumption of a mouse, which includes: detecting a moving speed of the mouse; and transmitting packets with a low report rate when the moving speed of the mouse is less than a default value.
