Abstract
An image projection device for projecting an image on a projection object includes a detecting unit configured to detect a detection object present within an object space corresponding to the image projected by the image projection device; a recognizing unit configured to recognize an instruction motion of a user based on detection of the detection object by the detecting unit; and an output unit configured to generate an output corresponding to the instruction motion recognized within the object space by the recognizing unit from the instruction motion and the image projected by the image projection device.

An image projection device for projecting an image on a projection object, the image projection device comprising:
- a detecting unit configured to detect a detection object present within an object space corresponding to the image projected by the image projection device;
- a recognizing unit configured to recognize an instruction motion of a user based on detection of the detection object by the detecting unit;
- and
- an output unit configured to generate an output corresponding to the instruction motion recognized within the object space by the recognizing unit from the instruction motion and the image projected by the image projection device.
An image projection system, comprising:
- an image projection device configured to project an image on a projection object;
- and
- an information processing device connected to the image projection device, wherein
- the information processing device includes
- a detecting unit configured to detect a detection object present within an object space corresponding to the image projected by the image projection device;
- a recognizing unit configured to recognize an instruction motion of a user based on detection of the detection object by the detecting unit;
- and
