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? May 11, 2005 Team. Space@Stanford 2

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 i. ROS/others Team. Space software Pilot implementation Academic Computing—Computer Science collaboration Space design considerations User studies Sustainability and scalability May 11, 2005 Team. Space@Stanford 3

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

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 May 11, 2005 Team. Space@Stanford 5

Nomads <—> digital natives 89% laptops for first-year students Proliferation of wireless Proliferation and convergence of devices (phone=camera= i. Pod=messaging) “Digital native” multitasking, collaboration, communication, cyberculture, new ways of learning (Trickle-up) pervasive computing has arrived May 11, 2005 Team. Space@Stanford 6

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 CS 2 c, “Intermediate Computing at Stanford” (pilot class for new media skills development i. e. audio, video, web, presentation May 11, 2005 Team. Space@Stanford 7

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

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 May 11, 2005 Team. Space@Stanford 9

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 Team. Space@Stanford 16

Space Design Considerations Flexibility over fixed Convertible Versatile Modifiable Cultural & social engineering Physical vs. technology investment [3] Monahan, Torin. 2002. May 11, 2005 Team. Space@Stanford 17

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 Team. Space@Stanford 18

Collaboration Technologies Horizontal/Vertical displays Multiple displays Tangible interfaces Physical object interfaces the virtual Integrated environments i. Room [4] Wang, H, Blevis, E. 2004 May 11, 2005 Team. Space@Stanford 19

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. [2] Johanson, B. , Fox, A. , Winograd, T. 2002. May 11, 2005 Team. Space@Stanford 20

User studies Design and Results One and two screens Groups Randomly formed groups Assignment: Develop presentation Find comfort level in communication and space Verbal communication Pre-existing groups Class project or student organization Greater ease in using the environment [1] Shih, C. , Fox, A. , Winograd, T. , Szybalski, A. , Crone, M. 2004 May 11, 2005 Team.

Discussion Your experience with changing users, technology, student culture, academic needs? To what extent do you feel similar pressures on your public technology spaces? Your experience with space design considerations, other ways to support collaboration, laptop users? May 11, 2005 Team. Space@Stanford 25
