89% laptops for first-year students
Proliferation of wireless
Proliferation and convergence of devices (phone=camera= iPod=messaging)
“Digital native” multitasking, collaboration, communication, cyberculture, new ways of learning
(Trickle-up) pervasive computing has arrived
May 11, 2005

7. Changing curricula and pedagogies
Project-based learning, problem-based learning (PBL)
Multimedia production, presentation
Required
Student-initiated
The new literacy, e.g. new Stanford Writing Requirement

8. Changing campus and residential life
Pervasive communication and connectivity
Merging of academic, social, personal, and community-building activities
Virtual and residence communities/ IM your roommate
Extracurricular cybercommunities, digital production needs
May 11, 2005

9. Specific needs for technology spaces
The same old stuff (workstations, printers, software)… and in addition…
High-end digital production
Mulitmedia presentation, performance, rehearsal
Partner and small-group collaboration
Laptops and emerging devices

16. Space design considerations
What are you seeking to enable?
What user experience(s) are you creating?
What rhythms are you creating?
As you shape the space, how does the space shape you?
May 11, 2005

17. Space Design Considerations
Flexibility over fixed
Convertible
Versatile
Modifiable
Cultural & social engineering
Physical vs. technology investment
[3] Monahan, Torin
May 11, 2005

18. Collaboration Design Considerations
Seating, shape, orientation=eye contact
Work surface
Same document or divide labor
Private vs. public information space
[4] Wang, H, Blevis, E. 2004
May 11, 2005

19. Collaboration Technologies
Horizontal/Vertical displays
Multiple displays
Tangible interfaces
Physical object interfaces the virtual
Integrated environments
iRoom

20. User studies Departure from public computing Move data & control
New way to structure collaboration
Working “over the shoulder” on one unit
Discuss and work separately, reconvene
Extension of the laptop
Share large displays
“See” the workspace
Public and private space
