The display device is incorporated in a vehicle, and the touch panel receives a pressing operation. The plurality of detecting units detect a pressure value on the touch panel.
Claims14
A display device incorporated in a vehicle, comprising:
- a touch panel that receives a pressing operation;
- a plurality of detecting units that detect pressure values on the touch panel;
- a storage unit that stores a vibration level indicating a vibration state of the vehicle, the vibration level being classified in advance according to a speed or an acceleration of the vehicle;
- a blocking unit that blocks a frequency band of the pressure values detected by the detecting unit, the pressure values corresponding to the vibration state of the vehicle and based on the vibration level indicating the vibration state of the vehicle, the vibration level being classified in advance according to the speed or the acceleration of the vehicle;
- and
- a calculating unit that calculates a pressed position based on a result of blocking by the blocking unit.
A display device incorporated in a vehicle, comprising:
- a touch panel that receives a pressing operation;
- a plurality of detecting means for detecting pressure values on the touch panel;
- a storage means for storing a vibration level indicating a vibration state of the vehicle, the vibration level being classified in advance according to the seed or an acceleration of the vehicle;
- a blocking means for blocking a frequency band of the pressure values detected by the detecting means, the pressure values corresponding to the vibration state of the vehicle, based on the vibration level indicating the vibration state of the vehicle, the vibration level being classified in advance according to the speed or the acceleration of the vehicle;
- and
- a calculating means for calculating a pressed position based on a result of blocking by the blocking means.
A display device incorporated in a vehicle, comprising:
- a touch panel that receives a pressing operation;
- a plurality of detecting units that detect pressure values on the touch panel;
- a blocking unit that blocks a frequency band of the pressure values detected by the detecting unit, the pressure values corresponding to a vibration state of the vehicle and based on a vibration level indicating the vibration state of the vehicle, the vibration level being set in advance;
- a calculating unit that calculates a pressed position based on a result of blocking by the blocking unit;
- and
- a storage unit storing a plurality of frequency components caused by vibrations of the vehicle corresponding to each vibration state of the vehicle, wherein the blocking unit decides a frequency component to be blocked based on the vibration state of the vehicle.
