Abstract
An interactive projection system and a projection method thereof are provided. The interactive projection system includes a projection region, a projection device, a touch device and a host. The touch device is movably disposed on the projection region. The projection device projects a corresponding input interface on a touch sensing surface of the touch device according to a position of the touch device, so as to improve usage convenience of the projection system.
Claims15
An interactive projection system, comprising:
- a projection region;
- a projection device, projecting an image beam to display a projection image on the projection region;
- a touch device, having a touch sensing surface, and movably disposed on the projection region;
- and
- a host, electrically connecting the projection device with the touch device, and configured to determine whether the touch sensing surface is located inside the projection region, the touch sensing surface is located outside the projection region or a part of the touch sensing surface is located inside the projection region,
- wherein when the touch sensing surface is located inside the projection region, the host controls the projection device to project a first input interface on the touch sensing surface, and when the touch sensing surface is located outside the projection region, the host controls the projection device to stop projecting the first input interface and the host takes no action in response to a touch operation on the touch sensing surface.
