2. May 11, 2005TeamSpace@Stanford2 of 25 Questions How are students, technologies, and academia changing? What pressures are these changes putting on public technology spaces? How can we better support pervasive, mobile computing? How can we better support partner and small-group collaboration?

3. May 11, 2005TeamSpace@Stanford3 of 25 Outline Rethinking technology spaces Changes in student users and technology Changes in curriculum, pedagogy, and campus life Real-time, real-space group collaboration Interactive Workspaces project (research project in CS) then opensource product iROS/others TeamSpace software Pilot implementation Academic Computing—Computer Science collaboration Space design considerations User studies Sustainability and scalability

4. May 11, 2005TeamSpace@Stanford4 of 25 Public technology spaces in education Outside the classroom Specialized spaces Purposes Learning, teaching Creativity, production Recreation, socializing Future: Immersive environments, VR, simulation

5. May 11, 2005TeamSpace@Stanford5 of 25 Our legacy tech spaces Created to provide access to computing But still used for…. Quick-hit email, Web, IM, etc. Printing, production work Productivity software Course-specific software Alternative study space Group/partner work Workstation usage declining

6. May 11, 2005TeamSpace@Stanford6 of 25 Nomads digital natives 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

7. May 11, 2005TeamSpace@Stanford7 of 25 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 CS2c, “Intermediate Computing at Stanford” (pilot class for new media skills development i.e. audio, video, web, presentation

8. May 11, 2005TeamSpace@Stanford8 of 25 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

9. May 11, 2005TeamSpace@Stanford9 of 25 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. May 11, 2005TeamSpace@Stanford16 of 25 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, 2005TeamSpace@Stanford20 of 25 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 [1] Shih, C., Fox, A., Winograd, T., Szybalski, A., Crone, M. 2004.
