Results

• 1st exp large static documents
• Task completion 21 and 36 faster
• 2nd exp dynamic dual attention task
• Error rate only 1/3 of two-monitor setup

25
What we learned

• We thoughtChip designers need it
• We learnedReal strength is dynamic content
• Have unexpected context information
• Two monitoring tasks at the same time
• Immersive tele-presence,remote operated vehicles
