Psychophysical experiments were conducted to measure the maximum stiffness under which virtual textured surfaces were perceived to be stable in a variety of conditions differing in texture model parameters, rendering method, and exploration mode. Unlike our previous study that used a collision detection algorithm with an inherent step change in force magnitude near the textured surface boundary, these experiments used an algorithm proposed by Ho et al. (1999) that produces continuously changing force magnitudes at the cost of increased computational complexity. We found that the stiffness thresholds resulted from the collision detection algorithm of Ho et al. were not always higher than those obtained with the algorithm used in (Choi and Tan, 2002). The stiffness thresholds depended on the texture rendering method and the exploration mode used in the experiments. We also discuss the types of instability experienced by the subjects and the corresponding characteristics of the proximal stimuli that invoked the perception of each type of instability. With this knowledge, our future work will investigate techniques to mitigate the problem of perceived instability.","PeriodicalId":177962,"journal":{"name":"11th Symposium on Haptic Interfaces for Virtual Environment and Teleoperator Systems, 2003.

A visual change-detection task was used as a measure of visual attention. Haptic taps on the back was used to prompt the user the visual quadrant within which changes occurred. The location of the haptic cues was consistent with the quadrant of the visual changes on either 80% or 20% of the trials. Ten subjects were randomly assigned to the two test conditions. The subjects were informed of the validity of the haptic cues before the experiments. We measured the effectiveness of haptic cues in terms of the changes in detection times in the visual task. Our results indicated that for the subjects in the 80% validity group, detection times decreased significantly with valid haptic cues, and increased significantly with invalid haptic cues. For the subjects in the 20% validity group, however, the results were less consistent. Some of the subjects benefited from haptic cues, while others managed to ignore the (mostly invalid) haptic cues. These results are interpreted as evidence that the use of haptic cues to reorient a person's visual spatial attention is natural and intuitive when the validity of the haptic cues is high. It is also concluded that the observed cross-modal attentional links between haptics and vision may involve a voluntary shift in attention as supposed to a purely involuntary mechanism.","PeriodicalId":177962,"journal":{"name":"11th Symposium on Haptic Interfaces for Virtual Environment and Teleoperator Systems, 2003.
