Manipulation input device, manipulation input system, and manipulation input method |
摘要 |
A manipulation input device includes a projection component, a photodetector, and a position calculator. The projection component is configured to project an image on a projection surface by scanning light from a light source. The photodetector is configured to detect as scattered light the light reflected by a manipulation object that has moved into a specific detection range including the projection surface. The position calculator is configured to calculate a distance of the manipulation object from a reference point based on a continuous detection duration during which the photodetector continuously detects the scattered light, the position calculator being further configured to calculate coordinates of the manipulation object on the projection surface based on the distance of the manipulation object from the reference point and position information indicating a scanning position of the light on the projection surface when the photodetector has detected the scattered light. |
