Augmented reality

Hi anyone know how to render a SL avatar in the real world as in http://www.youtube.com/watch?v=O2i-W9ncV_0 and as in http://www.youtube.com/watch?v=TPTlkSC7x6A&feature=related ?

The part in the first video just before the sequence showing the avatar demonstrates the equipment you need. Essentially the camera captures the room you are in, and the sensors determine your facing and position. Once you have that, the avatar is mixed into the real-world view, so it can be seen by a person wearing the glasses, or on a monitor screen.

Same thing with the table. They have an image capture program that reads the target on the table (the bar-code image) and uses that to determine angle of view, size, and position to impose the image onto the live video.

Many thanks Veritable for that, I was kind of aware of the broad concepts, what I need is to speak to someone who has done, or can do the nuts and bolts of it. The camera tracking and display technology has moved on making a SL and reality mix possible in specific real life urban environments.

There is a list of links to materials and an Augmented Reality mailing list at http://www.se.rit.edu/~jrv/research/ar/. It is a little out of date, but the mailing list should put you in contact with the right people.

Many thanks again Veritable. Yes the info is a little out of date, will pursue it, anyone else with hands on knowledge of Augmented reality?
