Dial box
Encyclopedia
A dial box is a computer peripheral for direct 3D manipulation
Direct manipulation interface
In computer science, direct manipulation is a human-computer interaction style which involves continuous representation of objects of interest, and rapid, reversible, incremental actions and feedback. The intention is to allow a user to directly manipulate objects presented to them, using actions...
