Abstract: Tracking the location and orientation of a user in an augmented reality application is generally power and processor intensive. While a relatively high degree of accuracy in user tracking may be required for visual augmented reality applications, a lesser degree of accuracy may be required for auditory augmented reality applications. Modified methods of pedestrian dead-reckoning may be used to effectively track a user, while keeping power consumption and computational load relatively small. An interactive auditory augmented reality experience, in the form of a haunted house game, may be produced without relying on GPS or visual tracking methods. Efficient user tracking methods allow a user to experience an interactive auditory augmented reality experience by using a relatively small auditory augmented reality device.

Abstract: A display that is capable of rendering objects to appear 3-D without use of special glasses or headsets is combined with a semi-reflective layer, such as a semi-silvered mirror. The display may be an auto-stereoscopic display that is mounted on the back side of the semi-silvered mirror. Camera systems generate image data representing an environment in front of the semi-silvered mirror and that image data is used to generate a three-dimensional model of the environment. Individuals may be identified and/or tracked using the image data. Eyes of the individual are tracked, and the eye tracking information is used with the auto-stereoscopic display to generate an augmented reality using the three-dimensional model. A viewer sees the augmented reality combined with the real world as reflected by the semi-silvered mirror.
