摘要
The present invention relates to an interactive whiteboard pointer of the type comprising a screen (3), a video projector (5), a camera (6) and a computer (7), said pointer comprising a body (8), a mechanical tip (9) of elongated shape extending along an axis XX 'and comprising an end (16) adapted to be brought into contact with a point on the surface of the interactive whiteboard forming the projection screen (3). According to the invention, the pointer comprises optical transmission means (17) capable of projecting a light beam (18) along an inclined axis with respect to the axis XX ', the axis of the light beam and the axis XX the point (9) intersecting in the vicinity of the end (16) of the mechanical point (9) so that the projection of said beam (18) in a plane transverse to the end of the mechanical point ( 16) is able to form a light spot (19) on the surface of the interactive whiteboard forming the projection screen (3), centered on the end (16) of the mechanical tip (9).
