Gesture map

  • Two grabs stretch or compress the bar by changing the distance.
  • Single grab repositions the bar in space.

Prototype notes

  • * sword grip 0.4
  • Designed for rapid iteration—only one glowing bar mesh and simple XR controller logic.
  • Hand tracking events update in real time; controllers fall back to trigger presses.
  • Clamp keeps the bar between 20 cm and 3 m to stay comfortable in-room.
