Abstract
A system and method for providing augmented reality. A method comprises retrieving a specification of an environment of the electronic device, capturing optical information of the environment of the electronic device, and computing the starting position/orientation from the captured optical information and the specification. The use of optical information in addition to positional information from a position sensor to compute the starting position may improve a viewer'"'"'s experience with a mobile augmented reality system.

15. A method for displaying an image using a portable display device, the method comprising:
-
computing a position/orientation for the portable display device; rendering the image using the computed position/orientation for the portable display device; displaying the image; and in response to a determining that the portable display device has changed position/orientation, computing a new position/orientation for the portable display device, wherein the computing makes use of optical position information captured by an optical sensor in the portable display device, and repeating the rendering and the displaying using the computed new position/orientation. - View Dependent Claims (16, 17, 18, 19)
