Control-Display mapping with three translational degrees of freedom

Situations in which the human operator must control three translational degrees of freedom are common in, for example, control of robot arms, remotely controlled cameras, and tele-surgery. Often, the operator has no direct view on the controlled object, but receives information on the motions of the object via a camera-monitor system or a...

Control display mapping in a 3D positioning task

Subjects have certain expectations about the mapping of motion directions of the control device on those of the controlled object on the accompanying display. When the actual mapping is according to this expectation, the relation is compatible. Compared to less compatible or even incompatible relations, less training is required, reaction times...
