  1. Focus plus context screens Patrick Baudisch, Nathan Good,and Paul Stewart UIST 2001, November 11th 2001

  2. Hardware • At least one hi-res display • At least one larger low-res display • Software • scaling of the display content is preserved • resolution varies <baudisch@parc.xerox.com>

  3. Contents • 1. What it is • 2. How it works • 3. What it is good for (video) • 4. Software • 5. Evaluation and conclusions

  4. How to build it?

  10. How does it work?

  11. 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])

  14. Evaluation

  15. Display technology homogeneous resolution 4 VisualizationSame # of pixels fisheye overview plus detail 5 4 4 wall-size, hi-res display focus plus context screen

  16. 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

  17. 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

  18. Try it out! • Demo: Tuesday 5.15
