A projection device () includes: a projector () adapted for projecting a mother image along a projection axis (); and a convex mirror adapted for at least partially reflecting the mother image and projecting it onto a three-dimensional environment () such as the ground, a ceiling, one or more side walls and the content of a room. When combining the projector with a convex mirror, the mother image can for example be projected into a solid angle higher than 2&#x3c0; steradians (i.e. a half-sphere), or even substantially equal to or slightly lower than 4&#x3c0; steradians (i.e. a sphere). A method implemented by the device is also described. The field of the invention is particularly that of video projectors for virtual or mixed reality applications.
