Handheld display device for navigating a virtual environment
First Claim
1. One or more non-transitory computer readable storage media comprising instructions that, when executed by a handheld computer having a visual display and one or more sensors, are capable of causing the handheld computer to:
- a. generate a virtual environment with a ground plane structure;
b. generate a signal to establish a location of a virtual camera in the virtual environment;
c. generate a signal to establish an orientation of the virtual camera in the virtual environment;
d. generate a signal to update the location of the virtual camera in the virtual environment in a direction of the orientation of the virtual camera on a plane parallel to the ground plane structure using x-axisometer data from at least one of the sensors indicating pivot up or pivot down of the handheld computer and an x-axisometer sensor reference data, wherein said use of x-axisometer sensor data to update the location of the virtual camera is effectively decoupled from use of v-axisometer sensor data, thereby enabling v-axisometer sensor data of the handheld computer to be used independently of x-axisometer sensor data of the handheld computer to update the orientation of the virtual camera; and
e. generate a signal to update the orientation of the virtual camera in the virtual environment using v-axisometer data from at least one of the sensors indicating pivot left or pivot right of the handheld computer and a v-axisometer sensor reference data, wherein said use of v-axisometer sensor data to update the orientation of the virtual camera is effectively decoupled from use of x-axisometer sensor data, thereby enabling x-axisometer sensor data of the handheld computer to be used independently of v-axisometer sensor data of the handheld computer to update the location of the virtual camera.

Abstract
Departing from one-way linear cinema played on a single rectangular screen, this multi-channel virtual environment involves a cinematic paradigm that undoes habitual ways of framing things, employing architectural concepts in a polylinear video/sound construction to create a type of experience that allows the world to reveal itself and permits discovery on the part of participants. Techniques are disclosed for peripatetic navigation through virtual space with a handheld computing device, leveraging human spatial memory to form a proprioceptive sense of location, allowing a participant to easily navigate amongst a plurality of simultaneously playing videos and to center in front of individual video panes in said space, making it comfortable for a participant to rest in a fixed posture and orientation while selectively viewing any one of the video streams, and providing spatialized 3D audio cues that invite awareness of other content unfolding simultaneously in the virtual environment.
