Abstract: An illumination device includes: a plurality of light source assemblies; and a plate-shaped optical unit on which light source light beams from the plurality of light source assemblies are incident from mutually different directions, and the plate-shaped optical unit is sectioned into a reflection surface and a transmission surface in accordance with an incident light intensity distribution of each of the light source light beams. Then, transmitted light having passed through the plate-shaped optical unit among the light source light beams and reflected light having been reflected by the plate-shaped optical unit among the light source light beams are emitted with directions aligned, and a boundary between the transmission surface and the reflection surface in the plate-shaped optical unit is formed at a position where incident light intensities of the light source light beams individually from the plurality of light source assemblies have substantially equal values to each other.

Abstract: Provided is a projection system using a projection device that simultaneously projects on a plurality of projection surfaces. A projection system includes: a user recognition unit that recognizes a user existing in a space; a projection environment recognition unit that recognizes a projection surface on which a video can be projected in the space; and a control unit that controls a projection device so as to project a video on the projection surface recognized by the projection environment recognition unit for the user recognized by the user recognition unit. The projection device can simultaneously project a video on a plurality of surfaces. The control unit controls a projection device so as to simultaneously project a video on two or more projection surfaces recognized by the projection environment recognition unit.
