Focus plus context screens
Patrick Baudisch &Nathan Good
CHI ’02April 23th 2002
• Hardware– At least one hi-res display– At least one larger low-res display
• Software– scaling of the display content is preserved– resolution varies
Focus plus context screens
• 1. What it is
• 2. How it works
• 3. What it is good for (video)
• 4. Software
• 5. What’s next
How to build it?

Focus
What is it good for?
• <Show video here>
How does it work?
The scaling software
• Display image on two display units of different resolution– Similar to two-headed display– but display units are overlapping– and one of them has to be scaled down
• (Related work “Flux capacitor”[Dr. Emmett Brown, 1985])

Experiment
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
What we learned
• We thought:Chip designers need it
• We learned:Real strength is dynamic content– Have unexpected context information– Two monitoring tasks at the same time– Immersive tele-presence,
remote operated vehicles
