| Research Abstract |
In this study, measurements of size-weight illusion in real environment have been made with using a real time multi-camera system. Results of the lifting height, velocity and acceleration of the bottles are computed and an interesting relationship between the motion information and the rate of illusion occurrence are analyzed. In the weight lifting experiments, subjects evaluated their perceptions of the lifted weight by the magnitude estimation method. Psychometric and psychophysical magnitude functions were computed according to subject's evaluation results. The slope of the psychometric function and the modality characteristic exponent were quantitatively analyzed for our experimental conditions. The results indicate that these quantities increase proportionally to lifting height. The results of this study demonstrate that weight perception in human is closely related to the motion of the upper limb.
