Direct 3D manipulation
Direct 3D manipulation is when a user can touch a virtual 3D object in a way that his finger or hand is at the same position that the object is. This emulates how humans pick up and interact with real physical objects.
Direct 3D manipulation is enabled by 3D control peripherals and 3D visual peripherals. Direct manipulation is a method of computer interaction that involves a user placing his finger in space directly at where an object appears to be to interact with it. It is when a users fingertip is at the exact point of a digital object controlled by the user.
3D direct manipulation can generally happen via hand tracking or with some types of 3D pens.
In 3D, this can be done with hand tracking and an augmented reality headset.
An extension of direct manipulation is to use a pen as a pointing device, where the tip of the pen is the point.
The first direct manipulation system for 3D was the Lincoln Wand.[1]
Devices[edit]
A Leap Motion Controller can be used for direct manipulation.
A haptic peripheral like a Geomagic Touch can be used.
A Polhemus Liberty or other electromagnetic tracking system can be used.
