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.
