The perception of surface velocity is crucial to dexterous control and object recognition. The first experiment determines the just noticeable difference (JND) in the speed and direction of slip using the \"method of adjustment\" difference threshold technique over a range of 80 to 240 mm/sec on two different surface textures. 42 subjects participated the first experiment. We find slip speed perception to be highly dependent on surface texture, with Weber fractions between 0.04 and 0.25. Slip direction difference thresholds range between 3.6 and 11.7 degrees, also highly dependent on surface texture. The second experiment establishes the relative importance of proprioceptive feedback versus slip feedback in perceiving surface velocity. For both surface textures, we utilize an alternative forced choice experimental technique on 40 subjects. We find that slip feedback at the fingertip only subtly influences the perception of speed over proprioceptive feedback from the hand and arm for the two different base speeds studied (250 and 400 mm/sec).","PeriodicalId":384123,"journal":{"name":"12th International Symposium on Haptic Interfaces for Virtual Environment and Teleoperator Systems, 2004.

In the proposed methodology, 5-axis tool motion and analytical tool swept volume are formulated for updating the virtual stock material, which is represented with dexel volume model. Based on the tool motion analysis, a dexel-based collision detection method and a force-torque feedback algorithm are proposed for virtual sculpting. Different from the traditional ways of calculating haptic forces based on depth of penetration or impulses, the proposed method determines the haptic force by finding the material removal rate of dexels. A lab-built 5-DOF haptic interface system is developed for the proposed haptic sculpting system. From the haptic sculpting system, both corresponding tool motion of the creative process and the sculpted model can be output. The tool motion can be recorded and output as NC (numerically-controlled) commands. The output STL model of the haptic sculpting system can be processed for machining planning.","PeriodicalId":384123,"journal":{"name":"12th International Symposium on Haptic Interfaces for Virtual Environment and Teleoperator Systems, 2004.

The manual interface becomes a haptic display, relaying information to the human about the intentions of the automatic controller while retaining its role as a manual control interface. The human may express his control intentions in a way that either overrides the automation or conforms to it. The automatic controller, by design, aims to create images in the mind of the human of fixtures in the shared workspace that can be incorporated into efficient task completion strategies. The fixtures are animated under the guidance of an algorithm designed to automate part of the human/machine task. Results are presented from 2 experiments in which 11 subjects completed a path following task using a motorized steering wheel on a fixed-base driving simulator. These results indicate that the haptic assist through the steering wheel improves lane keeping by at least 30% reduces visual demand by 29% (p<0.000!) and improves reaction time by 18 ms (p=0.0009).","PeriodicalId":384123,"journal":{"name":"12th International Symposium on Haptic Interfaces for Virtual Environment and Teleoperator Systems, 2004.

Force field training to facilitate learning visual distortions: a "sensory crossover" experiment 力场训练促进视觉扭曲的学习:一个“感官交叉”实验

Other work has shown that these two types of adaptation may share similar neural resources. One effective test of this sharing hypothesis would be to show that one could teach one using the other. This study investigated whether training with a specialized force field could benefit the learning of a visual distortion. Two groups of subjects volunteered to participate in this study. One group of subjects trained directly on a visual rotation. The other group of subjects trained in a \"mixed field\" condition. The mixed field was primarily a force field that was specially designed so that, after adapting to its characteristics, the subject would make the appropriate movement in the visual rotation condition. The mixed field condition also contained intermittent test movements that evaluated performance in the visual rotation condition. Results showed that errors reduced more rapidly in the mixed field condition. We also found that subjects were able to generalize what they learned to movement directions that were not part of the training, but there was no detectable difference between the two groups. Finally, we found no difference in the rate these training effects washed out after subjects returned to normal conditions. This study shows that training with robotic forces can facilitate the learning of visual rotations. The learning may be enhanced in the mixed condition by the addition of cutaneous and proprioceptive force sensors. Moreover, this study can be applied to telerobotics and the rehabilitation of brain injured individuals, where there is often a distortion in hand-eye coordination.","PeriodicalId":384123,"journal":{"name":"12th International Symposium on Haptic Interfaces for Virtual Environment and Teleoperator Systems, 2004.
