Abstract: A transfer-alignment system for a Head-Mounted Display (HMD), and a display coupled to the HMD, wherein the display is adapted to display images rendered by a display-processor, and wherein the HMD is monitored by a tracking system configured to provide information indicating position and/or orientation of the HMD with respect to a Frame of Reference (FoR), the system comprising: at least one first inertial sensor attached to the HMD and configured to acquire HMD's Inertial Readings Information (IRI); at least one second inertial sensor attached to the display and configured to acquire display's IRI; and a processor configured to: obtain the HMD's IRI, the display's IRI and the information indicating the HMD's position and/or orientation with respect to the FoR; continuously analyze movement information of the HMD and the display to determine relative orientation therebetween; and cause the display-processor to adjust the images to conform with respect to the FoR.

Abstract: A system for mapping a magnetic-field in a volume-of-interest comprising a magnetic-field transmitter, generating a magnetic-field in the volume-of-interest, a freestanding magnetic-field detector operative to freely move within the volume-of-interest, a pose-information-acquisition-module and a processor. The detector acquires measurements of flux of the magnetic-field at a plurality of poses. The pose-information-acquisition-module measures information related to the pose of the detector. The processor determines pose-related-information respective of at least a portion of the measurements according to the information related to the pose of the detector. The processor estimates the entire set of parameters of a magnetic-field model template according to the magnetic-field flux measurement and the respective poses-related-information thereof. The processor incorporates the entire set of parameters into the magnetic-field model template, thereby determining the magnetic-field model. The entire set of parameters includes the coefficients, the order the number and location of the centers of expansion of the magnetic-field model.

Abstract: A transfer-alignment system for a Head-Mounted Display (HMD), and a display coupled to the HMD, wherein the display is adjustable by a user along the at least one degree of freedom; and a processor configured to: obtain the HMD's inertial readings information, the display's inertial readings information and the information indicating the HMD's position and/or orientation with respect to the frame of reference; continuously analyze movement information of the HMD and movement information of the display to determine relative orientation between the HMD and the display; and cause the display-processor to adjust the images to conform with respect to the frame of reference based on the information indicating the position and/or orientation and the relative movements of the HMD, wherein the frame of reference is selected from the group consisting of a platform coordinates, a fixed coordinate system established in space, an earth coordinate system, and any combination thereof.
