Outline of Final Research Achievements

To explore the potential of projection mapping technique in the studies of neuroscience, we trained two macaque monkeys an object grasping task, and compared their behaviors between the conditions when real objects with various materials were presented and when the images of objects were presented by projection mapping. In both conditions, when objects which the monkey tended to avoid touching were presented, lowering of the facial temperature was observed. In addition, after exposure to the projection-mapped object, this monkey became to touch materials which it avoided to touch before the experiment. These results suggest that the object stimuli presented by the projection mapping technique were perceived to have high level of reality, and that this technique has potential to be applied for the behavioral experiments in neuroscience in which use of real objects are needed as the stimuli while it is difficult to prepare real objects.
