Tesseract 3D pointing device

Tesseract is a pointing device for three-dimensional virtual spaces. The aim of the project was to implement a novel but practical solution to navigation in three-dimensional Human-Computer Interfaces. Tesseract presents a 3D physical space within which the user can operate with six degrees of freedom (translation and rotation in X-Y-Z axes). A ball is suspended in a hollow cubic frame with elastics— the user moves and twists it in physical space which is mapped to the virtual 3D space. After every use, the elastics bring back the ball to its central position in the cubic space, which is the true zero.
