Abstract
A light emitting apparatus emits light toward a real space in which a user wearing a head-mounted display is present. The light emitting apparatus includes a first light emitting unit that emits first light, which is used as a reference signal, a second light emitting unit that emits second light, which is used as a scanning signal that scans the real space at a timing based on the reference signal, and a controller that controls the first light emitting unit. The reference signal includes notification information to be submitted to the head-mounted display.
Claims12
A light emitting apparatus that emits light toward a real space in which a user wearing a head-mounted display is present, the light emitting apparatus comprising:
- a first light emitting unit that emits first light, which is used as a reference signal;
- a second light emitting unit that emits second light, which is used as a scanning signal that scans the real space at a timing based on the reference signal;
- and
- a controller that controls the first light emitting unit;
- wherein
- the reference signal includes notification information to be submitted to the head-mounted display.
A head-mounted display that is attached to a user present in a real space and provides a virtual space to the user, the display comprising:
- a first light sensing unit that senses first light and acquires a reference signal including notification information to be submitted to the head-mounted display;
- a second light sensing unit that senses second light and acquires a scanning signal that scans the real space at a timing based on the reference signal;
- and
- an extracting unit that extracts the notification information from the reference signal.
