3-D Motion and Structure Estimation Using Inertial Sensors and Computer Vision for Augmented Reality

by Lin Chai, William A. Hoff, William A. Hoff (corresponding, Tyrone Vincent - Presence , 2000
"... A new method for registration in augmented reality (AR) was developed that simultaneously tracks the position, orientation, and motion of the user's head, as well as estimating the three-dimensional (3-D) structure of the scene. The method fuses data from headmounted cameras and head-mounted in ..."

Fusion of Data from Head-Mounted and Fixed Sensors

by William A. Hoff - Proc. of First International Workshop on Augmented Reality, IEEE , 1998
"... A methodology is developed to explicitly fuse sensor data from a combination of fixed and head-mounted sensors, in order to improve the registration of objects in an augmented reality system. The methodology was applied to the analysis of an actual experimental augmented reality system, incorporatin ..."

Viewing model for stereoscopic head-mounted displays

by David A. Southard - Proc. SPIE Stereoscopic displays and VR , 1994
"... We characterize a class of stereoscopic displays, which includes head-mounted displays that incorporate miniature cathode-ray tubes. We present a detailed viewing model that accounts for the placement, size, and orientation of the virtual display images. The model is appropriate for several types of ..."

of head-mounted display, as well as head-tracked stationary displays. The tracking algorithm accounts for the displacement between the tracking sensor and the user's eyes. We provide algorithms for calculating stereoscopic viewing and projection matrices. The algorithms are presented as parameterized

An Approach for User Identification for Head-Mounted Displays *

by Cynthia E Rogers , Alexander W Witt , Alexander D Solomon , Krishna K Venkatasubramanian
"... ABSTRACT A head-mounted display (HMD) is a device, worn by a person, which has a display in front of one or both eyes. HMDs have applications in a variety of domains including gaming, virtual reality, and medicine. In this paper we present an approach that can identify a user, from among a group of ..."

Tracking a Head-Mounted Display in a Room-Sized Environment With Head-Mounted Cameras

by Jih-fang Wang, Ronald Azuma, Gary Bishop Vernon Chi, Gary Bishop, Vernon Chi, John Eyles, Henry Fuchs , 1990
"... This paper presents our efforts to accurately track a Head-Mounted Display (HMD) in a large environment. We review our current benchtop prototype (introduced in [WCF90]), then describe our plans for building the full-scale system. Both systems use an inside-out optical tracking scheme, where lateral ..."

Dual Sensor Filtering for Robust Tracking of Head-Mounted Displays

by unknown authors
"... We present a low-cost solution for yaw drift in head-mounted dis-play systems that performs better than current commercial solutions and provides a wide capture area for pose tracking. Our method ap-plies an extended Kalman filter to combine marker tracking data from an overhead camera with onboard ..."
