Apart from that, he will also be rolling out his software as open source so that development of the entire project can be sped up. It took Cruz the better part of last year to build and develop an eye tracking computer interface that will work in tandem to the principles of electrooculography, which is the ability to measure the resting potential of the retina via electrodes that are located just beside the eyes. It will not track eye movements with the accuracy level of a high tech contact lens or video tracking system, but is affordable enough to be effective in helping the disabled use a computer.
Currently, Cruz’s sensor glasses are able to track horizontal eye movements only, but I am quite sure this is set to change in due time.
