Abstract
Recent research has found that real world objects are processed differently than image-based objects due to their affordances or ability to be handled and used a certain way. This study aims to test whether this technology holds the same implications as real-world objects, specifically in regards to visuomotor perception. In addition, the study also aims to support the use of an underlying cognitive mechanism such as dorsal activation outside of lower stereo cues such as shadows as the responsible party for the differences between formats. To test these theories, participants performed in a visuomotor task measuring grip aperture and just noticeable difference with different size stimuli in a real world, image, and object condition. While findings did not suggest any significant differences between real world objects and AR technology, findings do suggest a strong difference from the image condition as well as variability in the condition's adherences to Weber's law.
