Abstract
A virtual reality immersion system provides a head mounted display that contains a video camera and a video display. A plurality of target markers are distributed within a virtual environment room where each target is distinct from all other targets in the virtual environment room and distinct from rotated versions of itself. An automatic calibration program selects pair of targets from an image from the video camera. The selected pairs of targets are identified and the position of each target is calculated relative to the camera and relative to each other. The positions of each target pair are added to a list of relative target transforms. Video signals are processed to calculate the position of targets detected in each frame image using the relative target transforms and the effects of viewing angles are detected and a higher weight is given to targets that are detected at more reliable angles. The invention dynamically streams 3D content to the user through the video display. Once the target positions have been calculated, the invention determines the user position within the environment and when the user changes his viewpoint, the information from the calculated user position is used to change the position and angle of the 3D content and the 3D content is repositioned and streamed to the video display.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
