We propose a perceptually based system for pattern retrieval and matching. The central idea is that similarity judgment has to be modeled along perceptual dimensions. Hence, we detect basic visual categories that people use in their judgment of similarity, and design a computational model that accepts patterns as input and, depending on the query, produces(More)
This paper describes a practical synthetic visual environment for use in CAD and teleoperation. Instead of using expensive head mounted display systems, we use a standard display and compute smooth shaded images using an AT&T Pixel Machine. The interface uses a VPL DataGlove [9] to track the hand, bringing the synthetic world into the same space as the(More)
We determine the basic categories and the hierarchy of rules used by humans in judging similarity and matching of color patterns. The categories are: (1) overall color; (2) directionality and orientation; (3) regularity and placement; (4) color purity; (5) complexity and heaviness. These categories form the pattern vocabulary which is governed by the(More)
1. PANEL INTRODUCTION Following the great standards set by the panels in the workshops held in the last two years [1,2], we have this year again a distinguished panel to discuss and debate the directions and frameworks for telepresence. Some of the questions brought up in the last two years continue to be on the top of our minds: Why is telepresence not as(More)
We present a novel paradigm for human to human asymmetric collaboration. There is a need for people at geographically separate locations to seamlessly collaborate in real time as if they are physically co-located. In our system one user (novice) works in the real world and the other user (expert) works in a parallel virtual world. They are assisted in this(More)
A heterogeneous distributed system that enables people in geographically separate locations to share a common workspace is presented. In particular, the applicability of such a system to the notion of asymmetric collaboration is illustrated by a chess scenario. In our system one user (novice) works in the real world and the other user (expert) works in a(More)
