As public interest in mobile, wearable computing is on the rise, technology companies are rushing to develop wearable augmented reality (AR) display systems with embedded lightweight computing capabilities that strive to make mobile living effective, convenient, pleasant and aesthetic.

While we are already seeing some successful first-generation, commercially available lightweight wearable AR systems, the full potential of opportunities for mobile users (pedestrians, bicyclists, motorists) and headworn displays has not been fully tapped, nor the visual perceptual challenges widely understood. As we race to field headworn outdoor AR applications for mobile computing, we need to first understand, and then design for, the visuoperceptual issues that have been documented in the traditional AR community.

The goal of this work is better understanding effects of AR displays on:

  • Depth perception & color perception
  • Visual search & information processing
  • Context-switching and distance-switching in AR
  • Just noticeable differences, signal thresholds and Individual differences
