Document Summary

Design implications: maximize bottom-up processing: increase visibility and legibility; pay attention to confusion caused by similarity of message sets, maximize automaticity and unitization: use familiar perceptual representations. Ex: familiar fonts and lowercase text, meaningful icons and words over abbreviations: maximize top-down processing: when bottom up is poor and unitization may be lacking (unfamiliar symbology or language) by providing best opportunities for guessing. Ex: putting information in a consistent location: maximize discriminating features to avoid confusion, use smaller vocabulary, create context i. Downside: increase length of messages, reduce efficiency: exploit redundancy i. Downside: increase length of messages, reduce efficiency: consider expectations, test symbols and icons in their context of use i. Highlight negation: ex: do not turn off equipment.
