Abstract
When a gesture operation of a hand moving close to a display from left to right is performed, the return movement of the hand to the left side due to reflection by the wrist or the like may be detected. A detection control unit detects the approach of the hand to the display and notifies a data processing device of non-detection of hand approach when the amount of movement of the hand in the right direction starts to decrease after exceeding a threshold value. The data processing device accepts the right-moving gesture operation to perform a predetermined process when the amount of movement exceeds the threshold value.
Claims12
A proximity detection device configured to detect an approach of a user's hand to a display face of a display of a data processing device, the display being used as an input device for the data processing device, the proximity detection device comprising:
- an approach detection unit configured to detect whether the user's hand approaches the display face and a position, in a left-right direction, which a hand approaches using an infrared light source that is disposed outside the display face of the display and emits infrared light that passes in front of the display face and a photodetector that is disposed outside the display face and detects reflected light of the infrared light;
- and
- a notification unit configured to output non-detection to the data processing device when the approach detection unit does not detect an approach of the user's hand, and to output the position in the left-right direction detected by the approach detection unit to the data processing device when the approach detection unit detects an approach of the user's hand, wherein
- one of a left direction and a right direction is set as a first direction, and the notification unit outputs non-detection to the data processing device when an amount of movement of a position detected by the approach detection unit in the first direction decreases after exceeding a predetermined threshold value during a period of detecting that the approach detection unit is detecting an approach of the user's hand.
A proximity detection device configured to detect an approach of a user's hand to a display face of a display of a data processing device, the display being used as an input device for the data processing device, the proximity detection device comprising:
- an approach detection unit configured to detect whether the user's hand approaches the display face and a position, in an up-down direction, which a hand approaches using an infrared light source that is disposed outside the display face of the display and emits infrared light that passes in front of the display face and a photodetector that is disposed outside the display face and detects reflected light of the infrared light;
- and
- a notification unit configured to output non-detection to the data processing device when the approach detection unit does not detect an approach of the user's hand, and to output the position in the up-down direction detected by the approach detection unit to the data processing device when the approach detection unit detects an approach of the user's hand, wherein
- an upward direction is set as a first direction, and the notification unit outputs non-detection to the data processing device when an amount of movement of a position detected by the approach detection unit in the first direction decreases after exceeding a predetermined threshold value during a period of detecting that the approach detection unit is detecting an approach of the user's hand.
