Binaural horizontal perspective display
The present invention display 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.
1 . A method of three dimensional image display by horizontal perspective projection and 3-D audio system projection, the horizontal perspective projection comprising a display of horizontal perspective images according to a predetermined projection eyepoint, and the 3-D audio system projection comprising providing 3-D sound according to a predertermined projection earpoint, the method comprising the steps of:
detecting an eyepoint location of a viewer;
displaying a horizontal perspective image using the detected eyepoint location as the projection eyepoint; and
projecting a 3-D sound to the viewer using the eyepoint location as the projection earpoint.
2 . A method as in claim 2 wherein the 3-D sound comprises two sound channels and a HRTF (head related transfer function) filter.
3 . A method as in claim 2 wherein the 3-D sound comprises a 3-D loudspeaker audio system or a 3-D headphone audio system.
4 . A method of three dimensional image display by horizontal perspective projection and 3-D audio system projection, the horizontal perspective projection comprising a display of horizontal perspective images according to a predetermined projection eyepoint, and the 3-D audio system projection comprising providing 3-D sound according to a predertermined projection earpoint, the method comprising the steps of:
continuously scanning to detect an eyepoint location of a viewer;
calculating a new horizontal perspective image using the detected eyepoint location as the projection eyepoint;
displaying the new image;
calculating a new 3-D sound using the detected eyepoint location as the projection earpoint; and
displaying the new 3-D sound.
5 . A method as in claim 4 wherein the 3-D sound comprises two sound channels and a HRTF (head related transfer function) filter.
