Researchers and developers have been working on ways to offer 3-D images and videos without having to use any special glasses. And now it seems that they are certainly getting closer to their goal as a recent demonstration by researchers at France’s Engineering Human-Computer Interaction Research Group shows how ‘head tracking’ can enable 3-D display on Apple’s iPad 2.
The head tracking software works, as you might expect, by tracking your head movements (called Head-Coupled Perspective Technique) to provide a 3-D image. The 3-D image generated by this mechanism actually extends into the screen which creates an impression that you are looking through a window. Since, the software needs a front facing camera this could very well be achieved on an iPhone 4 too.
