title: Direction-of-turn stereotypes - conflict and concord.
abstract: Three principles are described which affect the design of 'workable' control-display relations for vertical linear displays with a rotary control. These principles facilitate each other with some control-display configurations, strengthening the stereotyped expectation for the effect of a particular control movement. In other configurations the principles oppose each other; here 'Warrick's Principle' emerges as strongest but is weakened by the opposing action of an alternative principle.
