Evaluation of a display incorporating quantitative and check-reading characteristics

Abstract

It was demonstrated that the conventional method of red lining a dial to indicate a deviation from 'safe and normal' operation is significantly better than no 'redline' indication at all provided the criteria are errors, or reading time isolated from associated motor activity. It was also demonstrated that the experimental dial design principle is significantly more efficient than the other two. (PsycInfo Database Record (c) 2025 APA, all rights reserved)
