Our experiment will investigate distance judgments in computer generated 2D displays. Distance judgments in 2D images are made all the time in fields such as architecture and design, the medical field and satellite images. Our experiment will investigate the role of the depth cues shadows and texture. A 2D display of a desktop with between 5 to 8 objects will be presented to participants. Each scene will have two conditions: high quality (simulations of objects with correct texture and shadow information) and low quality (objects have incorrect texture information and no shadows). Unit-less relative distance judgments will be made between objects to determine if the visual cues texture and shadow information aid in spatial perception. An eye tracker will be used to determine on which visual cues participants rely. Results will provide information about how shadow and texture information in 2D displays are used in spatial perception. Our hypothesis is that participants will be more accurate in high quality conditions. We also expect participants to focus on shadow and texture information in the high quality condition. In contrast, participants will use object geometry to judge distances in the low quality conditions.
