LEGIBILITY OF SEGMENTED VERSUS STANDARD NUMERALS: THE INFLUENCE OF THE OBSERVER'S TASK.
Abstract
In many current visual display techniques, numerals are formed by a pattern of individually illuminated segments. Laboratory research has indicated, generally, that such 'segmented' numerals are not so easy to read as standard Arabic numerals. Research results suggest that in some practical, complex tasks these laboratory differences disappear. In this series complexity of the observer's task, and his freedom to control his viewing were systematically varied. As task complexity or allowable viewing time, or both, increased, measured legibility differences between segmented and Arabic numerals tended to disappear. (Author)
