  • Evaluation of Interaction Devices for Ndi Training in Vr: Gamepad Vs. Joystick
    Proceedings of the Human Factors and Ergonomics Society Annual Meeting, 2020
    Co-Authors: Sajay Sadasivan, Deepak S Vembar, Paris Stringfellow, Andrew T. Duchowski, Anand K. Gramopadhye
    Abstract:

    Recent advances have led to the development of a virtual simulator to be used for non-destructive inspection (NDI) training of aviation maintenance technicians. The simulator is distinctive in that it has been developed to simulate a general type of NDI job aiding tool (video Borescope), as opposed to only simulating a precise model and make. By generating a simulator based on a generic model of the video Borescope, the development process must face a common hurdle: determining the best interaction device for the task at hand. In the real world, video Borescopes come in a variety of shapes and sizes, as do their interaction devices. In this case, the team must decide upon the best interaction device to be used while ensuring the retention of inspection information from training and facilitating interaction ease of use, all while not permanently engraining the skills that will be needed to control the actual devices when actually used. In short, the interaction device chosen for this simulator should facil...

  • visuohaptic Borescope inspection simulation training modeling multi point collision detection response and evaluating skills transfer
    Graphics Interface, 2010
    Co-Authors: Deepak S Vembar, Andrew T. Duchowski, Anand K. Gramopadhye, Melissa Paul, Carl Washburn
    Abstract:

    Results are presented from a transfer effects study of a visuohaptic Borescope simulator developed for non-destructive aircraft inspection training. The Borescope simulator supports multi-point collision detection to effect haptic feedback as the virtual probe slides along and collides with rigid surfaces. Such probe maneuvering is shown to be a significant aspect of the inspection task that benefits from training, regardless of whether a real or virtual probe simulator is used to provide the training.

  • improving simulated Borescope inspection with constrained camera motion and haptic feedback
    Graphics Interface, 2009
    Co-Authors: Deepak S Vembar, Andrew T. Duchowski, Anand K. Gramopadhye, Carl Washburn
    Abstract:

    Results are presented from empirical evaluation of a Borescope simulator developed for non-destructive inspection training. Two experiments were conducted, manipulating camera rotation constraint and provision of haptic feedback. Performance of experienced Borescope inspectors is measured in terms of speed and accuracy, with accuracy clearly shown to improve by placing constraints on the simulator's camera tip rotation and by providing haptic response. This is important as damage avoidance of a real Borescope is a critical criterion of Borescope inspection training. These are likely to be the first such experiments to have been conducted with aircraft engine inspectors evaluating the potential of haptics in Borescope simulation.

  • WACV - Real time tracking of Borescope tip pose
    Proceedings Third IEEE Workshop on Applications of Computer Vision. WACV'96, 1996
    Co-Authors: Ken Martin, Charles V Stewart, R. Hammond
    Abstract:

    The authors present a technique for the real-time tracking of Borescope tip pose. While Borescopes are used on a regular basis to inspect machinery for wear or damage, knowing the exact location of a Borescope is difficult due to its flexibility. They present a technique for incremental Borescope pose determination consisting of off-line feature extraction and on-line pose determination. The feature extraction precomputes from a CAD model of the object the features visible in a selected set of views. The on-line pose determination starts from a current pose estimate, determines the visible model features, projects them into a two-dimensional image coordinate system, matches each to the current Borescope video image (without explicitly extracting features from this image), and uses the differences between the predicted and matched feature positions in a gradient descent technique to iteratively refine the pose estimate. The approach supports the mixed use of both matched feature positions and errors along the gradient within the pose determination. The on-line system is designed to execute at video frame rates, providing a continual indication of Borescope tip pose.
