  1. Focus plus context screens Patrick Baudisch

  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. <Show video segment>

  4. Focus plus context screens • What it is • How it works • How to build one • Application scenarios (video) • The software • Evaluation • What we learned from practitioners (field study) • How much faster, how much more accurate(lab experiment) • Conclusions

  5. How to build it?

  6. Setup

  11. How does it work?

  12. 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])

  15. Evaluation

  16. Field study • Who are the potential users? • Do they lack display space? • What do they currently use? • What tasks should we simulate?

  17. Subject’s task Document/view Smallest object Smallest detail Ratio Static documents Web designer Page: 800 pixel Text: 10 pixel Table detail: 1 pixel 800 Mechanical engineer Polybot segment: 5cm Pin: 1mm Clearance: 0.03mm 2,000 Graphic designer Poster: 1m Text: 1cm Align: 0.5mm 2,000 Architect in remodeling Building: 50m Wall: 10cm Accuracy: 1cm 5,000 Photogrammetry (2) Highway 2 miles Curb: 6 inches Accuracy: 1 inch 100,000 Geographic info. system County: 80km Trees: 5m Land boundaries: 0.5m 160,000 Chip designers (2) Wafer: 12cm Conductive path: 3m Grid: 0.5m 240,000 Dynamic Air traffic ctrl. tool builder Zone: 50km Airplane: 50m Plane distance in 25m steps 2,000 Ego shooter gamer Surrounding: 360º Distant opponent: 1º Aiming: 0.1º 3,000 Submarine ROV op.

  19. Lab experiment • how much faster? • how much more accurate? • how much more satisfying?

  20. Experiment 1:“static documents” • 3 interfaces: • focus plus context screen • overview + detail • homogeneous • 2 tasks • 12 subjects from Xerox PARC • Within subjects, counter-balanced • Same number of pixels

  21. Task 1: Closest hotel 8 maps per interface F+C screen and O+D use same magnification factor

  22. Task 2: Verify connections Verify a different set of 24 connections on the board

  23. Map task Board task z+p (N=12) 453.3 (236.6) 568.3 (187.1) f+c (N=12) 325.0 (176.4) 378.8 (71.2) o+d (N=12) 414.0 (199.9) 593.5 (232.0) Results 21% faster 36% faster manually zoomingtakes time visually switching between views is ok but reorientation takes time Average task completion times in seconds (standard dev.) visually more ambiguous

  24. Experiment 2:Driving simulation 120 sec sequence 100 fields of nails; 30 rocks; tradeoff

  25. o+d f+c Run-over nails 20.9 (10.3) 9.5 (4.1) Rocks hit 6.6 (3.1) 1.9 (1.9) Results Error rate only 1/3 of two-monitor setup Mean number of collisions subjects caused in the car task (and standard deviation). Subjects preferred thef+c interface

  26. 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

  27. If I had to commercialize today… • Build all-analog immersive video link • Immersive telepresence, • Remote operated vehicles, drones • Immersive VR • Remote medicine
