Abstract
Three variables were manipulated in an attempt to determine the conditions of optimal performance using object-like displays. Uniquely color coding the vertices of the object did not appear to cause a significant change in separate or integral task accuracy. The introduction of a display based on the Gestalt law of closure in which the middle third of each side of the object was removed improved separate task accuracy relative to the object display. Separate task accuracy for the closure display was not as good as the bar display. Integration task accuracy was not harmed by this manipulation. The validity of the emergent feature for information integration was manipulated. Lower levels of validity reduce integration task accuracy for all displays equally. Thus, if information integration is the operator's primary task, display designers should consider using the closure display in place of the object display. The usefulness of both object and closure displays may be limited since the emergent feature may be less than 100% valid for the information integration task in many real world situations. This is due to constraints in the geometry of object displays.
