Isomorphic interaction
Isomorphic interaction is a type of computer input where there is a cursor that is displayed, but the user's hand is in a different place in the physical world than where the cursor is, but the direction of movement of the cursor is the same as the person's hand or finger.
It is called isomorphic because the movement is the same, although in a different place. The movement of a person's hand or finger corresponds directly to movement of a displayed cursor in a virtual space. It can be done using electromagnetic 3D tracking systems. It is one type of spatial computing.
It encompasses isomorphism of acceleration with modified virtual physics, for example, a mouse pointer with acceleration. Strict isomorphism to only position and rotation is limited to specific products like drawing tablets.
Isomorphic interaction uses a strict geometric isomorphism (one-to-one mapping) between physical and virtual objects.[1] For example, the interaction provided by a Phantom Premium 1.5 6DOF device. You move the device in a specific motion, and the cursor in the virtual world moves in the same way.
