Abstract
A projection apparatus includes a work state detector configured to detect a state of work of mounting or removing a component; and a light source controller configured to stop emission of light from a light source or reduce brightness of the light emitted by the light source, in response to determining that the state detected by the work state detector is start of the work.
Claims8
A projection apparatus comprising:
- a work state detector configured to detect a state of work of mounting or removing a component;
- and
- a light source controller configured to stop emission of light from a light source or reduce brightness of the light emitted by the light source, in response to determining that the state detected by the work state detector is start of the work.
An interactive system comprising:
- a projection apparatus;
- a terminal apparatus;
- and
- an operation instruction device, wherein
- the projection apparatus includes:
- an interactive controller configured to detect an infrared light emitted by the operation instruction device and transmit position information representing a position of the infrared light to the terminal apparatus;
- a work state detector configured to detect a state of work of mounting or removing the interactive controller;
- and
- a light source controller configured to stop emission of light from a light source or reduce brightness of the light emitted by the light source, in response to determining that the state detected by the work state detector is start of the work, and wherein
- the terminal apparatus is configured to receive the position information representing the position of the infrared light, and to implement a content of an operation based on the received position information.
