| Outline of Final Research Achievements |
To investigate the mechanism of weight perception, we conducted psychophysics experiments using virtual reality system. In the experiment using a physics simulator of the cubic objects moving 3-dimensional world, we found a possibility that our brain is utilizing prior knowledge about the relationship between the speed and the mass of objects and the weight perception might be the result of Bayesian inference using those prior knowledge. We also conducted the experiment in which subjects hold several objects by robot-arm controlled by the subjects’ EMG signal. We found that the information about the size of objects, efferent motor command signal, and the trajectory of the objects play important role on weight perception.
