Electronic Interactive projection device

The projection device for displaying an interactive digital content to be projected on a surface, characterized in that it comprises a projection frame (2, 3, 5) comprising a part (5) forming a base of maintenance, the projection frame (2, 3, 5) comprising: ▪ a transmitter (30, 61) of a light beam (31) in a non-visible frequency band forming a light sheet to cover a first zone (Z1 ) of a surface; ▪ A projector (20) projecting an image (22) on a second area (Z2); ▪ A first detector (10, 60) capturing an image of the second zone (Z2); ▪ A calculator (K) determining at least a position of at least one interaction point (33) of the light beam (31) through analysis of a trace (32) of the image acquired by the first detector ( 10).
