AI Technical Summary

Technical Problem

In mixed reality (MR) and augmented reality (AR), the mismatch between the real and virtual viewpoints during a walk-through function causes communication difficulties among users observing a virtual 3D model, as others cannot understand the point of gaze of the user.

Method used

An information processing device that acquires and shares real and virtual viewpoints between users, generating a composite image with avatars and visual effects to align the virtual and real viewpoints, using head-mounted displays (HMDs) to present a mixed reality image.

Benefits of technology

Resolves inconsistencies between real and virtual viewpoints, allowing users to understand each other's positions and orientations during a walkthrough, enhancing communication in MR and AR environments.

Abstract

To solve inconsistency of a relation between a virtual viewpoint of another user and a real viewpoint.SOLUTION: An information processing device 217 shares a space where a virtual three-dimensional model is presented with another user. The information processing device has: acquisition means which acquires information on a real viewpoint of the other user; and generation means which generates a video effect based on the information on the real viewpoint of the other user, when a virtual viewpoint of the other user is different from the real viewpoint of the other user.SELECTED DRAWING: Figure 2
