Binaural horizontal perspective hands-on simulator
The present invention hands-on simulator system discloses a three dimension display system comprising a three dimensional horizontal perspective display and a 3-D audio system such as binaural simulation to lend realism to the three dimensional display. The three dimensional display system can futher comprise a second display, together with a curvilinear blending display section to merge the various images. The multi-plane display surface can accommodate the viewer by adjusting the various images and 3-D sound according to the viewer's eyepoint and earpoint locations. The present invention hands-on simulator system can project horizontal perspective images into the open space and a peripheral device that allow the end user to manipulate the images with hands or hand-held tools.
