Erg-O: Ergonomic Optimization of Immersive Virtual Environments
summary
Erg-O uses optimization-based retargeting and full-body/hand tracking to keep virtual objects visually fixed while mapping their physical reach points to more comfortable locations via paired tetrahedral spatial partitioning. Two retargeting strategies—group spatial consistency and per-object ergonomic optimization—are implemented. A user study across three layouts shows ergonomic scores improve significantly, task time sometimes improves (significant differences between strategies and versus a virtual-hand baseline), and perceptible redirection is minimized by limiting displacement to about 6–10 cm.
