Visual Distraction Is Obvious

Cognitive Demand Harder to “See”

Leaving the Consumer BehindDriving is an extreme environment - Intuitiveness is critical • Balance – needs of novice users vs.
desires of lead adopters
• Designs that vary from previous experiences or provide little connection to experiences can be difficult to learn and may compromise safety
• Successful designs build on users’ existing experience (mental models)

Where Are We and Where Do We Go from Here?
• Technology info today– The manual– DVD’s & the web– Sales staff– Friends– Trial and error
• The opportunity – designs that are intuitive will engage consumers and minimize workload– “Technology delivery”
– Interactive assistance
