The GT3D system uses a pair of gaming cameras to provide 3D computer control
The system tracks both eyes with great precision and accuracy
Bioengineers at Imperial College, London have developed a new computer controller for paraplegics that is not only more accurate and easier to use than current methods, but also uses inexpensive, off-the-shelf components. The GT3D device uses a pair of eyeglass frames with two fast video game console cameras costing less than UKP20 (US$30) each, which scan the wearer’s eyes from outside the field of vision and provide “3D” control at much lower costs and without invasive surgery.
