Grasping lacks depth constancy in both virtual and real environments.
The use of virtual reality setups allows sophisticated manipulations of visual and haptic feedback important for the study of grasping movements. On this respect, the absence of feedback is shown to induce different systematic biases in visuomotor tasks, such as underestimation of the target distance and, above all, lack of the target depth constancy. The latter is revealed by a decrease in gri...
متن کاملLack of depth constancy for grasping movements in both virtual and real environments.
Recent studies on visuomotor processes using virtual setups have suggested that actions are affected by similar biases as perceptual tasks. In particular, a strong lack of depth constancy is revealed, resembling biases in perceptual estimates of relative depth. With this study we aim to understand whether these findings are mostly caused by a lack of metric accuracy of the visuomotor system or ...
متن کاملanalysis of iranians’ writing performances in virtual and real environments
writing has always been considered an important literacy skill for foreign/second language learners. the internet provides such unique applications for the writing skill as weblogs, wikis, and social networking websites. up to now researchers have put their focus on the learners’ performances in the traditional paper and pencil environment or wikis and blogs it is time to also consider learners...
متن کاملImitation learning for reaching and grasping in virtual environments
In addition to trial and error learning, learning from observed teacher generated examples may greatly facilitate acquisition of motor skills. I present results for an imitation learning reaching and reaching-to-grasp controller for a Virtual Reality environment with simulated physics. The controller follows the unforced dynamics of a localized vector field around the human example data with no...
متن کاملGrasping Real Objects Using Virtual Images
This paper describes a fundamentally new approach to vision-based control in robotics. In particular, the problem of grasping diierent objects using a robot with a singe camera mounted on the end-eeector (an eye-in-hand system) is considered. In the proposed approach the recognition of the object, and thereby the identiication of its grasp position, the subsequent translational and rotational p...
