Virtual Viewpoint Camera Position Markers for Performer Gaze Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In systems generating virtual viewpoint images, performers lack guidance on where to direct their gaze since there is no real camera at the virtual viewpoint position, restricting their performance in studios and similar settings.
Innovation Solution
A processing system comprising multiple image capturing units and a presenting unit that determines the orientation of objects in space, using a network of cameras and projectors to display markers indicating the virtual camera position, allowing performers to align their gaze with the virtual viewpoint.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a plurality of cameras are arranged to capture images for generating virtual viewpoint images, then the realism and variety of viewing angles are improved, but the performer's ability to direct their gaze is worsened due to lack of visual cues about camera positions
Solution Approach 1:
The patent introduces markers as intermediary visual elements that mediate between the invisible virtual camera positions and the performer's gaze. These markers are displayed on screens positioned around the performance space, providing direct visual guidance to performers about where to direct their attention, thereby solving the contradiction between maintaining realistic virtual viewpoint generation and enabling effective performer gaze control
Solution Approach 2:
The patent creates a visual copy or representation of the virtual camera positions through markers displayed on physical screens. Instead of directly showing the invisible virtual camera locations, the system projects marker images onto physical surfaces that performers can see and respond to, effectively copying the spatial information in a perceptible form that guides performer behavior
