Experimental Study on Virtual Texture Force Perception Using the JND Method
This paper presents an experimental investigation on virtual texture force perception, where the Just Noticeable Difference (JND) method is used to evaluate the effects of texture spatial period and human exploratory speed on texture force perception. Two experiments have been conducted in this stud...

Two experiments have been conducted in this study. The first experiment focused on JNDs of texture force under different spatial periods (0.055–90mm) without limiting subjects' exploratory speeds. It was found that JNDs of texture force were between 6.20% and 9.80%. The spontaneous exploratory speed was highly affected by spatial period.

The spatial period had a significant effect on JNDs of texture force, which decreased as spatial period increased in the range of 2.9–14.9mm. Although the subject's exploratory speed has no noticeable effect on JNDs of texture force, the effect of interaction between spatial period and exploratory speed was significant. The experiment result indicated that when texture spatial period is small, low exploratory speed can be chosen to get small JND of texture force.https://doi.org/10.5772/50533 |

This paper presents an experimental investigation on virtual texture force perception, where the Just Noticeable Difference (JND) method is used to evaluate the effects of texture spatial period and human exploratory speed on texture force perception.

It was found that JNDs of texture force were between 6.20% and 9.80%. The spontaneous exploratory speed was highly affected by spatial period. It increased and then became stable as the spatial period increased. The second experiment assessed the effect of spatial period and human exploratory speed on JNDs of texture force. The spatial period had a significant effect on JNDs of texture force, which decreased as spatial period increased in the range of 2.9–14.9mm.
