A Voxel-based Grid Coordinate for Virtual Object Positioning in Outdoor Mobile Augmented Reality
Presented at IEEE VR 2026 Posters; explores human-friendly spatial referencing for outdoor AR.
This project was presented at IEEE VR 2026 Posters.
Humans perceive and describe space using relative expressions, while computers use absolute coordinates. This difference creates a gap in spatial communication, especially in outdoor environments where objects with complex surfaces serve as references. To address this, I presented a voxel-based surface grid coordinate system for outdoor mobile augmented reality. This approach voxelizes reference object models obtained from a 3D map and defines grids on them. Each surface grid maps to geographic coordinates and provides a surface-based index for placement. Quantitative outdoor experiments and a pilot user study showed how surface grids and visual cues can support spatial perception at different levels.
