Focus plus context screens
Patrick Baudisch, Nathan Good,and Paul Stewart
UIST 2001,
November 11th 2001
• Hardware– At least one hi-res display– At least one larger low-res display
• Software– scaling of the display content is preserved– resolution varies

What is it good for?

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])

Evaluation
• Field study– 12 professionals, 2 gamers– Nobody uses overview plus detail– A list of tasks for the experiments
• 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
