AI Technical Summary

Technical Problem

Conventional eye-sensing light field display technologies can only perform line-of-sight recognition for one person at a time, limiting the ability to create a shared three-dimensional experience for multiple viewers without causing discomfort.

Method used

An image display system with a display capable of simultaneously displaying different images in multiple directions, combined with user viewpoint position calculation and image generation units to create a shared three-dimensional experience for multiple viewers by generating and displaying images from individual user perspectives.

Benefits of technology

Enables multiple people to view a shared virtual three-dimensional world without discomfort, as if the objects exist beyond the display, by accurately calculating and displaying images from each viewer's perspective.

Abstract

To achieve an effect that gives an illusion as if a three-dimensional world or a three-dimensional object exists, without a sense of discomfort for all the persons who are viewing a display when a plurality of persons simultaneously view the display with naked eyes, related to an image display technique that displays on the display an image that is seen when a three-dimensional object in a virtual three-dimensional space is viewed from the position of a user.SOLUTION: A display 104 has a screen that can simultaneously display different images in a plurality of display directions. An image generation unit 102 generates a display image of a three-dimensional object in a virtual space via a screen from a user viewpoint position for each of one or more user viewpoint positions in a user space on the front side of the screen where one or more users who view the images displayed on the screen of the display 104 may exist. An image display unit 103 displays a display image generated according to the viewpoint position for each user viewpoint position on the screen of the display 104 in the user viewpoint position direction corresponding to the user viewpoint position.SELECTED DRAWING: Figure 1
