A six degree of freedom (DOF) hand controller is a device that can be used for the simultaneous control of multiple axes. These kinds of control tasks are common in areas such as teleoperation. Multi-axis control may be problematic as a consequence of interference I.e., the control of a certain DOF affected the simultaneous control of another. Irrespective whether the cause of this interference lies in the operator's motor system ...
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 simplified graphical display. In the design of such systems, it is important that the mapping ...
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 are faster, less errors are made, and mental workload is lower in compatible control display relations. Concerning this mapping ...
