Experimentation and Modeling of Human-Computer Interaction

Abstract

This talk will give a brief overview of recent findings in my study of human-computer visual interaction (HCVI) and the use of the EPIC cognitive architecture to simulate HCVI.

The visual modality is, and will likely continue to be, the highest bandwidth channel between the computer and the user. While a large body of basic research on visual search exists in psychology, there has been comparably little research on the application of basic psychological phenomena. I will present research that investigates, with reaction time and eye movement data, the effect of local density on the visual search of structured layouts of words. Recent findings in this research have identified possible strategy shifts due to changes in local density. The EPIC cognitive architecture will be used to investigate these strategy shifts. EPIC is an framework for building models of human performance that account for cognitive, perceptual, and motor capabilities of humans. Future directions in this research, including applications for research and modeling of human-computer-human interaction (also called computer mediated interaction), will be discussed.
