ABSTRACT
An interactive, dynamic map has been built using videodisc technology to engage the user in a simulated “drive” through an unfamiliar space. The driver, or map reader, is presented with either sparsely sampled sequences of images taken by single frame cameras that replicate actual imagery from a space, or with computer synthesized replicas of those images. The reader may control the speed, route, angle of view and mode of presentation of this information and may thus tour the area. In addition, he may access spatially stored ancillary data stored in the buildings or in locales in the environment. This basic map is being enhanced to provide topographic views, and to incorporate optical and electronic image processing to provide a more responsive, visually complete representation of an environment.

Images as embedding maps and minimal surfaces: movies, color, and volumetric medical images
CVPR '97: Proceedings of the 1997 Conference on Computer Vision and Pattern Recognition (CVPR '97)A general geometrical framework for image processing is presented. We consider intensity images as surfaces in the (x, I) space. The image is thereby a two dimensional surface in three dimensional space for gray level images. The new formulation unifies ...
The case for the narrative brain
IE '05: Proceedings of the second Australasian conference on Interactive entertainmentNarrative is important for interactive systems because humans have narrative brains. In this paper, reviewing the case for the narrative brain from various fields of psychology and narrative theory, three themes emerge. The first theme is that there is a ...
