The Engineering Human-Computer Interaction Research Group has recently published a paper on how to achieve 3D without glasses on mobile devices. According to the research, Head-Coupled Perspective (HCP) on mobile devices can be used to create a glasses-free monocular 3D display. It is based on a efficient head-tracker that uses the front-facing camera of the device. An off-axis projection is used in order to adapt the perspective of the 3D scene according to the head's position of the user. I should say I am really amazed. A demo of the same can be see on you tube.
The important thing to check is not just how to show 3D but to create a sustainable solution. Many people complained of headaches after playing nintendo 3DS. I am not sure if we will ever achieve a complete 3D experience on a 2 dimensional device (without glasses). The trick that can be a "Wow effect" but I am not sure if it can be a end of search for a "solution" to 3D without glasses. I sometimes feel its all a waste of time and money because someone has not understood the problem statement correctly. But then I also think it will be unjust to criticise as any trick can trigger an idea for The Solution !
I will probably wait for the vision of George Lucas! :) And that would be the beginning of a new era.
