Virtual Reality/Augmented Reality/Mixed Reality
I really confused about the difference of these three technologies. For this reason, I did research from wikipedia, and find different answers.
First, ‘Virtual Reality (VR) is an environment that is simulated by a computer.’ (It is the most clearly definition for me to understand.)
About Augmented Reality, some one states, ‘Augmented Reality was introduced as the opposite of virtual reality: instead of diving the user into a synthesized, purely informational environment, the goal of AR is to augment the real world with information handling capabilities.’
Other arguments say: ‘VR is a special case of AR, in the sense that AR adds to what VR already does.’ Or ‘Augmented Reality displays will overlay computer-generated graphics onto the real world. AR is concerned with the use of live video imagery which is digitally processed and "augmented" by the addition of computer generated graphics’.I think the following explanation would be more suitable: The TV overlay isn't a very good example for Augmented Reality since by some definitions it isn't AR at all. Ronald T. Azuma defined AR as systems which:1. Combine the virtual and the real2. are interactive in real time3. registered in 3DAugmented Reality is to enhance their field of view with virtual elements usually generated by a computer.
Mixed Reality is ‘the merging of real world and virtual worlds to produce a new environment where physical and digital objects can co-exist and interact.’ Probably a specialisation of augmented reality and interactive media(i guess).
Honestly, I still unable to distinguish AR and MR very clearly. There is some clips to view from http://video.google.com/videoplay?docid=-4891862904939433910. (don’t know how to upload them, Sorry ar =) ).
