Abstract: Operation of a car navigation system in which a menu is in a hierarchical structure can be performed by simple gestures. The method includes: detecting that a switch is pressed; subsequently detecting a gesture by a sensor; obtaining, from a memory unit, an operation associated with the detected gesture; and outputting, with respect to a screen displayed on a display unit at the time of detecting the gesture, a result of performance of the obtained operation to the display unit, wherein once it is detected that the switch is released, if it is detected that the switch is subsequently pressed again within a predetermined period of time, the same process is repeated.

Abstract: An accurate determination of an operation is possible. Data photographed by a video camera is read by an image reading unit, and an image of an operator is extracted from the data by an image extracting unit.

Abstract: Two bar support portions are provided on opposite sides of a floor mat sensor and a horizontal bar is fixed between these portions to define spaces below into which feet are to be inserted. Then, using the horizontal bar as a reference, an input area, such as “A” or “B”, can be accurately stepped on. A signal receiver reads and stores a first signal, and a signal determination unit determines whether the signal that was read was generated by stepping on area A or area B. Thereafter, when a signal is received indicating a data type was received first, the signal receiver reads the next input signal and the signal determination unit determines whether a signal indicating the data type was received.
