3D Virtual Viewer

A device with an optical display device which can determine its position in space while being moved, can change its optical output characteristic as defined by image data.

One simple implementation consists of an LCD display attached to a multi-axis inertial sensor and a storage device holding image data. As the operator moves the display device through space, the display changes so that a small viewport, corresponding to a part of the full view is visible to an observer.

Application areas for  such a device exist outside of  entertainment and amusement.

Image data that are virtual can be 3-dimensional schematics and/or digital scanned images not visible to the naked eye.  The virtual viewer is then useful tool for e.g. identifying equipment during physical maintenance by following a schematic in 3 dimensions simply by directing and moving the viewer through the space in which the equipment has been installed.
