ABSTRACT:
I will present an overview of our mixed reality research work at the Vision and Media Computing Laboratory of the Nara Institute of Science and Technology (NAIST), Japan. Our main research topics are Augmented Reality, Augmented Virtuality, Wearable Computing and Computer Vision. One of the research topics is user tracking in indoor and outdoor environments. For tracking a user who ‘wears’ a mobile computer in an indoor environment, we proposed an invisible marker consisting of retro-reflectors, whose color is similar to the color of the ceiling. Users cannot commonly see the marker with their bare eyes. However, the marker can be observed with IR cameras using IR LEDs, and can be used to estimate the position and orientation of the user. We will also present some techniques for Photorealistic Augmented Reality. One of the techniques deals with geometric and photometric registration, considering image quality for augmented reality. In addition, Augmented Virtuality techniques, which represent the real world in a virtual world will be presented.
