Human Movement Performance in Relation to Path Constraint - The Law of Steering in Locomotion
We examine the law of steering – a quantitative model of human movement time in relation to path width and length previously established in hand drawing movement – in a VR loc...

Revisiting path steering for 3D manipulation tasks
The law of path steering, as proposed by Accot and Zhai, describes a quantitative relationship between human temporal performance and the path’s spatial characteristics. The ste...

Scale effects in steering law tasks
Interaction tasks on a computer screen can technically be scaled to a much larger or much smaller sized input control area by adjusting the input device's control gain or the...
