PRISM

Also known as Precise and Rapid Interaction through Scaled Manipulation

Adjusts control-display gain according to hand movement speed to support precise selection and manipulation in immersive environments.

How it works

When the hand moves slowly, its motion is scaled down so the ray or object moves less than the hand, allowing precise selection. Fast movements map one-to-one, and the offset is recovered over time.
