[Abstract]In this study, experiments of weight detection in real environment have been made. A real time multi-camera system was used to measure the motion of the lifted bottles during weight detection. The size-weight illusions were confirmed in most groups for almost all subjects. Results of the lifting height, velocity and acceleration of the bottle's motion are computed and an interesting relationship between the motion information and the occurrence rate of illusion are demonstrated. Method of time profile analysis was also made for all experiments. The results show that the time period of dropping the bottle is notably longer than the time period of lifting the bottle. This fact provides a strong evidence to support our hypothesis proposed in the previous study that the weight cognition is achieved in the later half of the up-down movement
