Abstract

The Project consists in developing a rotating 3D image projector through optical illusion. The proposition is to use a 16x16 LED matrix rotating at high speeds with each LED being activated in precise timing. The goal is to create illusions of simple tridimensional figures such as a cube, a sphere and a cylinder amongst others. The project in question is part of a branch of research in brain-computer interface. So, after finalizing the device, it will be integrated with a BCI (Brain Computer Interface), so that a person can use to control the 3D images generated by the device. (AU)
