Augmenting a Laser Pointer with a Diffraction Grating for Monoscopic 6DOF Detection
This article illustrates the detection of 6 degrees of freedom (DOF) for Virtual Environment interactions using a modified simple laser pointer device and a camera. The laser pointer is combined with a diffraction rating to project a unique laser grid onto the projection
planes used in projection-based immersive VR setups. The distortion of the projected grid is used
to calculate the translational and rotational degrees of freedom required for human-computer interaction purposes.
