Input apparatus and method

摘要

An input apparatus and method for use in an information input unit. The information input unit is coupled to an information device having a display. The input apparatus includes an operational selection module, which is coupled to the information input unit, for generating a press signal in response to a pressing operation detected by the operational selection module and for generating a shift signal in response to a shifting operation detected by the operational selection module. A control chip of the information input unit activates the information device to display a graphical interface indicative of a set of options on the display when the information input unit receives the shift signal. Selection of the set of options on the graphical interface is made according to the press signal and the shift signal.
