  1. Focus plus context screens Patrick Baudisch &Nathan Good CHI ’02April 23th 2002

  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

  3. 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

  4. How to build it?

  5. Setup

  6. b Seamless integration of displays a

  7. Context No reflections on focus screen Focus

  8. What is it good for?

  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])

  16. “Hand’s on” demo all week in the Commons`

  17. Future work: ContextWall Submitted to CSCW

  18. Extra slides

  19. Evaluation

  20. Subject’s task Document/view Smallest object Static documents Web designer Page: 800 pixel Text: 10 pixel Mechanical engineer Polybot segment: 5cm Pin: 1mm Graphic designer Poster: 1m Text: 1cm Architect in remodeling Building: 50m Wall: 10cm Photogrammetry (2) Highway 2 miles Curb: 6 inches Geographic info. system County: 80km Trees: 5m Chip designers (2) Wafer: 12cm Conductive path: 3m Dynamic Air traffic ctrl. tool builder Zone: 50km Airplane: 50m Ego shooter gamer Surrounding: 360º Distant opponent: 1º Submarine ROV op. Surrounding: 360º Small fish: 1cm/0.5º Strategy gamers (2) Map: 30k pixel Missile: 3 pixel Field study

  21. Experiment

  22. 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

  23. 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
