The Influence of Head Tracking and Stereo on User Performance with Non-Isomorphic 3D Rotation

چکیده
We present an experimental study that explores how head tracking and stereo viewing affect user performance when rotating 3D virtual objects using isomorphic and non-isomorphic rotation techniques. Our experiment compares isomorphic with non-isomorphic rotation utilizing four different display modes (no head tracking/no stereo, head tracking/no stereo, no head tracking/stereo, and head tracking/stereo) and two different angular error thresholds for task completion. Our results indicate that rotation error is significantly reduced when subjects perform the task using non-isomorphic 3D rotation with head tracking/stereo than with no head tracking/no stereo. In addition, subjects performed the rotation task with significantly less error with head tracking/stereo and no head tracking/stereo than with no head tracking/no stereo, regardless of rotation technique. The majority of the subjects tested also felt stereo and non-isomorphic amplification was important in the 3D rotation task.

Stereo-Based Head Pose Tracking Using Iterative Closest Point and Normal Flow Constraint
In this text, we present two stereo-based head tracking techniques along with a fast 3D model acquisition system. The first tracking technique is a robust implementation of stereo-based head tracking designed for interactive environments with uncontrolled lighting. We integrate fast face detection and drift reduction algorithms with a gradient-based stereo rigid motion tracking technique. Our s...
متن کاملImproving Appearance-based 3d Face Tracking Using Sparse Stereo Data
Recently, researchers proposed deterministic and statistical appearance-based 3D head tracking methods which can successfully tackle the image variability and drift problems. However, appearance-based methods dedicated to 3D head tracking may suffer from inaccuracies since these methods are not very sensitive to out-of-plane motion variations. On the other hand, the use of dense 3D facial data ...
متن کاملAn overview of head tracking integral imaging three-dimensional display using smart pseudoscopic-to-orthoscopic conversion
We overview a previously reported head tracking integral imaging three-dimensional (3D) display to extend viewing angle accommodated to a viewer’s position without the crosstalk phenomenon. A head detection system is applied to obtain the head position and rotation of a viewer, and a new set of elemental images is then computed using the smart pseudoscopic-to-orthoscopic conversion (SPOC) metho...

A head tracking system for automatically detecting and tracking human heads in complex backgrounds is developed. In this paper, two issues are addressed: the detection of human heads and the development of a head tracking system. First, based on an elliptical model for the human head, we propose a Maximum Likelihood (ML) detector to reliably locate human heads in images having complex backgroun...

A simple 3D virtual mirror interface system is proposed for acquisition and reconstruction of facial pattern, which enables a real time tracking of 3D facial pattern. The movement of lip in the face, which can be estimated based on mean shift and Kalman filter is introduced to recognize the rotation and parallel shift of face. Modified Photometric Stereo Method (PSM) is also proposed to acquire...
