Kadobayashi, Rieko and Tanaka, Katsumi (2005): 3D viewpoint-based photo search and information browsing. In: Proceedings of the 28th Annual International ACM SIGIR Conference on Research and Development in Information Retrieval 2005. pp. 621-622. Available online

We propose a new photo search method that uses three-dimensional (3D) viewpoints as queries. 3D viewpoint-based image retrieval is especially useful for searching collections of archaeological photographs, which contain many different images of the same object. Our method is designed to enable users to retrieve images that contain the same object but show a different view, and to browse groups of images taken from a similar viewpoint. We also propose using 3D scenes to query by example, which means that users do not have the problem of trying to formulate appropriate queries. This combination gives users an easy way of accessing not only photographs but also archived information.

Igarashi, Takeo, Kadobayashi, Rieko, Mase, Kenji and Tanaka, Hidehiko (1998): Path Drawing for 3D Walkthrough. In: Mynatt, Elizabeth D. and Jacob, Robert J. K. (eds.) Proceedings of the 11th annual ACM symposium on User interface software and technology November 01 - 04, 1998, San Francisco, California, United States. pp. 173-174. Available online

This paper presents an interaction technique for walkthrough in virtual 3D spaces, where the user draws the intended path directly on the scene, and the avatar automatically moves along the path. The system calculates the path by projecting the stroke drawn on the screen to the walking surface in the 3D world. Using this technique, the user can specify not only the goal position, but also the route to take and the camera direction at the goal with a single stroke. A prototype system is tested using a display-integrated tablet, and experimental results suggest that the technique can enhance existing walkthrough techniques.
