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.

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.

a photosensor structure; andswitching means coupled between the photosensor structure and one of the plurality of signal lines, the switching means responsive to select signals on one or more of the plurality of select lines for conveying a photosensor signal between the photosensor structure and the one of the plurality of signal lines.
