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.

Claims

1. A method performed by a car navigation device having a sensor for capturing an image of a gesture of a user, a memory unit which stores an operation with respect to the car navigation device in which an operation menu is in a hierarchical structure and a gesture of a user in association with each other, a switch, and a display unit, the method comprising the steps of:

(a) detecting that the switch is pressed;

(b) capturing an image of a gesture via the sensor while the switch is pressed;

(c) obtaining, from the memory unit, an operation associated with the captured image of the gesture;

(d) outputting, with respect to a screen displayed on the display unit at the time of capturing the image of the gesture, a result of performance of the obtained operation to the display unit; and

(e) detecting that the switch is released,

wherein the step (b) to the step (e) are repeated with an operation menu corresponding to previously performed operation if it is detected that the switch is pressed again within a predetermined period of time from executing the step (e).

2. The method according to claim 1, wherein the step (b) to the step (e) are repeated with a same operation menu as that of last time if it is detected that the switch is pressed again after a predetermined period of time.

3. The method according to claim 1, wherein the car navigation device further includes a light, and with performing of the step (a) as a trigger, the light is turned on and with performing of the step (e) as a trigger, the light is turned off.

4. The method according to claim 1, wherein in the step (d), in addition to output to the display unit, the result of performance is output by voice output.

5. A car navigation device performing the method according to claim 1.

6. A non-transitory computer readable storage medium which stores a computer program for causing a computer to execute the method according to claim 1.
