1. Tensegrity Over Compression
The old model viewed the body like a stack of blocks (compression). v2 utilizes Biotensegrity. We now treat the skeleton as a tension-based structure. This means we focus on the pull and slack of the system. By adjusting the tension in the fascia, we allow the bones to "float" into better alignment naturally, rather than forcing them. Cervical (C1-C7) Thoracic (T1-T12) Lumbar (L1-L5) Sacrum and
This allows developers to measure spinal torsion—the twisting force that leads to lower back pain—in real time. For ergonomic software, this is a game-changer.
Furthermore, the system leverages temporal coherence. If your hand is behind your back, the standard v2 would lose tracking. The Extended Skeleton Edition uses a physics-based predictive model. It knows the last known position, velocity, and joint constraints of your elbow and shoulder to infer the hidden hand’s pose. This "shadow tracking" reduces dropouts by nearly 40% in occlusion-heavy scenarios.
