Emerging display technologies allow computer-generated objects to be presented alongside the real world with rapidly increasing fidelity. These technologies hold the potential to enhance our interactions with the world, particularly in challenging environments. They also offer a new means for investigating and understanding the functioning of human sensory systems. This project will use these virtual and augmented reality (VR, AR) display technologies to examine the perception of shape and distance over very long ranges, such as those found when viewing natural landscapes. Having been comparatively overlooked by previous researchers, VR and AR offer the means to rigorously assess the accuracy and precision of human far-distance perception. In examining these issues, we will quantify the information used by human observers in judging distance over very long ranges and provide a suite of tools to help improve human performance in such tasks.
