  • Publication number: 20110006988
    Abstract: A multi-mode mouse device includes a mode-switching element on a surface of a mouse body. By manipulating the mode-switching element, the mouse device could be operated in a working mode or a power-saving mode according to the user's requirements. In the working mode, the response cycle of the motion sensor within the mouse device is maintained constant. In the power-saving mode, the response cycle is adjusted according to the downshift time period of the mouse device. By manipulating the mode-switching element, the mouse device could meet the demands of achieving optimal sensitive degree and power-saving efficacy.
