We examined the temporal and spatial resolution of Kinect which is a motion sensing input device manufactured by Microsoft. Specifically, two experiments were conducted to verify Simon effect and Muller-Lyer illusion by measuring quantitative behavior using Kinect. The purpose of experimental 1 was to evaluate the temporal resolution of Kinect in a Simon effect task. Simon effects were observed in both of the keyboard condition and the Kinect condition. In experimental 2, participants were asked to judge the length of the Mueller-Lyer test line compared to the comparison line either by perception or hand action. In the Kinect condition, hand-action judgement of the line increased with the line length linearly. More importantly, the hand-action condition did not show significant illusions while the perception condition showed significant illusions. This result suggests that Kinect could be a useful tool to explore a possible gap between perception and action. Finally, several methodological problems and future developments of the Kinect system were discussed.
