Identifying the Pose Between a Head Mounted Display and a Head Pose Sensor
Craig Reynolds, Louis J. Everett, Richard A. Volz · 2000
Abstract Head mounted displays (HMDs) are common hardware in a virtual reality environment. Sensors are commonly installed on the helmet to provide information about where the operator is looking. If the operator rotates the helmet, the virtual scene should rotate correspondingly. If the point of rotation (POR) of the operator’s head differs from the POR used to transform the image, the display may behave in bizarre ways. In “enhanced reality” and similar applications the virtual scene must also accurately correspond to the real world. When the virtual scene must accurately correspond to a real scene, it becomes necessary to accurately match the virtual display to the real world. A method for automatically collecting data to align these scenes is described and demonstrated in this paper. A theoretical basis for the method and experimental data are presented. Results indicate that the underlying assumptions of the theory are reasonable and that the errors in the method are reasonable.
