perceptual integration. Curvature arises in a fundamental way, and this explains and expands
collinear facilitation, as well as exceptions and individual differences. It further clarifies certain
alignment differences as arising from texture continuation rather than curve continuation, and
leads to new predictions about the variation of angular differences with displacement.
Computational examples support the curvature-based models for realistic imagery.
2040 PRESIDENTIAL SYMPOSIUM
Psychology meets technology
Convener and Chair: M. Denis, France
2040.1 Developing cognitive design principles for computer created diagrams, B. Tversky,
Stanford University, Stanford, CA, USA
Effective diagrams, such as route maps and assembly instructions, should be designed according
to two principles: Congruity, according to which elements and relations of diagrams should
correspond to elements and relations of the desired cognitive structures; Apprehension, according
to which elements and relations in diagrams should be readily perceived and accurately conceived.
Research on segmentation of events and production and comprehension of diagrams informs the
design principles. The principles have been translated into algortihms for generating
individualized diagrams for route maps and object assembly, which users have praised. The
methods apply broadly to interfaces and visualizations.
2040.2 Cognitive psychology and technology of learning: A mutual regard, E. Bigand,
Université de Bourgogne, Dijon Cedex, France
The purpose of the talk is to illustrate some of the striking interactions that pertain between
cognitive psychology and technology. We present examples of research taken from different fields
(music psychology and cognitive ergonomics) that illuminate the interests for cognitive
psychology to integrate technology in the core of the research program. We start by focusing on
the contributions of technology to simulate the working of cognitive processes. Then we consider
technology as a real cognitive tool that can facilitate the processing of information, specifically in
learning situations. We close this talk by considering the interest for technology to integrate
cognitive psychology in its development.

The term Augmented Reality (AR) is used to describe systems that blend computer generated
virtual objects or environments with real environments (Azuma, 1997; Barfield & Caudell, 2000).
Using an AR system, it is possible to display virtual objects that are attached to the surrounding
physical environment or to the participants' body when they are moving in the physical
environment. The investigation explores whether experiencing an array of virtual objects attached
to the environment or the body will affect the participants' choice of different frames of reference
to represent location of objects and to recalibrate human spatial updating of object locations.
