VolRec: haptic display of virtual inner volume in consideration of angular moment

In this paper, we propose a haptic device which displays the virtual inner volume inside using angular moment. The device is developed using a linear motion guide, a weight and a motor which can control the height of the center of the gravity. Also, psychophysical experiment was carried out to evaluate our device. By conducting a regression analysis on the result of the experiment, there was a significant effect on user perception of the inner volume. Based on the result, we created several applications with our proposed method to show the usage.
