Virtual fixtures as tools to enhance operator performance in telepresence environments

  title={Virtual fixtures as tools to enhance operator performance in telepresence environments},
  author={L. Rosenberg},
  booktitle={Other Conferences},
This paper introduces the notion of virtual fixtures for use in telepresence systems and presents an empirical study which demonstrates that such virtual fixtures can greatly enhance operator performance within remote environments. Just as tools and fixtures in the real world can enhance human performance by guiding manual operations, providing localizing references, and reducing the mental processing required to perform a task, virtual fixtures are computer generated percepts overlaid on top… Expand
Preliminary Study on Real-Time Interactive Virtual Fixture Generation Method for Shared Teleoperation in Unstructured Environments
The proposed method allows a human operator to intuitively assign various types of virtual fixtures on-the-fly to provide virtual guidance forces helping the operator to accomplish a given task while minimizing the cognitive workload. Expand

Point cloud augmented virtual reality environment with haptic constraints for teleoperation
A novel methodology for haptic constraints in a point cloud augmented virtual reality environment is proposed to address this human operation limitation and can enhance human operation efficiency and reduce time costs by at least 59% compared with no-haptic-constraint operations. Expand
Learning to perform a new movement with robotic assistance: comparison of haptic guidance and visual demonstration
These results indicate that both forms of robotic demonstration can improve short-term performance of a novel desired path and the motor system is inclined to repeat its previous mistakes following just a few movements without robotic demonstration, but these systematic errors can be reduced with periodic training.
