Voxel Heat Maps for 3D Virtual Object Placement Across Viewers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to effectively distribute virtual objects in 3D virtual spaces, especially when multiple viewers have limited or no control over virtual cameras, leading to inefficiencies in placement and viewer experience.
Innovation Solution
Utilizing a voxel-based heat map to intelligently place virtual objects by assigning weights to voxels based on their proximity to the field of view, with higher weights for voxels within the field of view and decaying weights over time, allowing for flexible and scalable placement strategies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If virtual objects are placed randomly or manually in 3D virtual spaces, then placement simplicity is maintained, but viewer accessibility and engagement are reduced
Solution Approach 1:
The system pre-calculates and generates heat maps showing optimal placement locations for virtual objects before actual placement occurs. This preliminary analysis of viewer trajectories and field of view data enables intelligent placement decisions that maximize viewer engagement without requiring complex manual intervention during runtime
Solution Approach 2:
Heat maps serve as an intermediary data structure that mediates between viewer behavior data and virtual object placement decisions. The heat map accumulates and visualizes optimal placement zones, allowing the system to intelligently distribute virtual objects based on predicted viewer engagement without requiring direct complex calculations at placement time
2Adaptability or versatility
If multiple virtual cameras are used to cover different viewer perspectives, then viewer coverage is improved, but object placement complexity increases
Solution Approach 1:
The system merges multiple field of view data from different virtual cameras into a unified heat map representation. By combining perspective data from multiple cameras and accumulating viewer trajectory information across all viewpoints, the system generates comprehensive heat maps that guide placement for multi-camera scenarios without requiring separate complex placement logic for each camera
Solution Approach 2:
The heat map generation system serves multiple functions: it works for single-camera and multi-camera scenarios, handles different viewer trajectories, and adapts to various virtual object types. This universal approach simplifies placement complexity by providing a single framework that handles diverse viewing conditions
3Productivity
If virtual objects are placed to maximize visibility for all viewers, then viewer engagement increases, but control over specific placement locations is reduced
Solution Approach 1:
The system allows designers to specify partial constraints on virtual object placement while maintaining intelligent optimization. Rather than fully controlling exact placement coordinates, designers can define boundary conditions or preferred zones, and the heat map system intelligently places objects within those constraints to maximize viewer engagement without complete loss of designer control
