1. P3-Systems Person to Person to Place
  • P3 systems involve the use of mobile devices that
    record location and time, and collect this
    information for use in applications.

P3-Systems Framework
System Design Approaches System Design Approaches Synchronous Communication or Synchronous Location Awareness Asynchronous Communication or Asynchronous Location Awareness
People Centered Absolute User Location Where is my buddy now? Where has my buddy been?
People Centered Co-location / Proximity Who is close to me now? Who has my geotemporal routines?
Place Centered Use of Physical Spaces by People Who is in this place now? Who uses this place regularly?
Place Centered Interactions in Matching Virtual Places Who can I talk to in this place? What did people have to say about activities in this place?

2. The SmartCampus Initiative
  • PIs- Constantine Manikopoulos (ECE) Quentin
    Jones (IS)
  • Other Faculty Involved
  • B. Amento (IS and ATT), C. Borcea (CS), S.R.
    Hiltz (IS),
  • Katia Passerini ( Management)

SmartCampus is
  • A mobile, wireless campus community system that
    will serve as a dispersed laboratory for the
    study of People-To-People-To-Places (P3) Services
    in terms of studies of
  • Community building
  • Co-ordination of mobile teams
  • User privacy personal location data and other
    concerns and
  • Security

9
SmartCampus Overall Goal
  • To improve geographically concentrated social
    connectivity/ capital through the use of our
    People-to-Peopleto-Place (P3) systems.
  • We believe that its use can lead to more social
    interaction, more collaborations, and larger and
    more inter-connected social networks, thus
    building the overall strength of community.
  • But many potentially negative social impacts as
    well as technical issues are of concern.

10
Hardware/ Equipment
  • Provisioning 500 students with personal
    computing devices (smart phones and tablet PCs),
    which will run a suite of applications central
    server to run the applications
  • Locatability is achieved through a modified
    version of Intels PlaceLabs code, and complete
    WiFi coverage of our campus, which is
    complimented by a small number of WiFi access
    points that do not provide connectivity but
    rather act as beacons to improve location
    accuracy.
  • We can now locate within about five feet, show
    the location on a real-time map, and identify a
    place name.

11
Initial Client Technologies
  • Wi-FiBluetooth enabled - TabletPCs, Notebooks,
    HandComputers locatable from 5-20m indoors and
    outdoors at NJIT.
  • PDAs Wi-FiBluetooth and PDA phones
    GSMWi-FiBluetooth
  • GSMWi-FiBluetooth SMARTphones locatable from
    5-15m indoors and outdoors at NJIT.
  • Wearable Group Heads Up Displays, Twiddlers,
    OQOs, More

12
Initial Applications / Systems
  • First field site to cover entire design space
  • NJITs Active Campus Explorer
  • NJITs SmartCampus Web/WiKi
  • NJITs CampusMesh
  • GeoMemory System
  • SmartCampus Middleware
  • CampusBorgs
  • Security Protection Systems ConexGuard

13
Location-aware applications in various stages of
development and deployment include
  • NJITs ActiveCampus Explorer (modified from
    UCSD version), which enables map based buddy
    tracking, location aware instant messaging, and
    digital graffiti
  • SmartCampus WiKi which provides context aware
    editable web pages about NJIT places, people and
    organizations according to location and season
    via an analysis of wireless access point used and
    DNS lookup
  • GeoMemory an in situ multi-media and location
    aware capture tool for mobile phones and
  • CampusMesh a location-aware friend-of-friend
    system for social introductions and reminders.

14
Some Overall Research Questions
  • What kinds of people will want to use these
    applications, and for what?
  • What kinds of concerns about privacy and
    interruptions, vs. convenience and benefits? How
    are these related to place, time, and the
    characteristics of the users?

15
Completed three rounds of semi-structured
interviews
  • Round one, results available and to be summarized
    today based on scenarios- with a cross section
    of 65 students, faculty and staff.
  • Round two students, based on working prototype
    of CampusWiki
  • Round three faculty, reactions to walkthroughs
    of mockups of Campus Mesh

16
Methodology
  • The first set of semi-structured interviews were
    conducted with a cross section of representatives
    of types of users (students and faculty and
    staff residents and commuters undergraduates
    and graduates, etc.) during the first few months
    of test-bed development.
  • Students in research courses interviewed and
    transcribed
  • Thus, the opinions gathered at that time were
    used to influence the features and even the name
    of the systems under development.

17
Interview Guide
  • At the time of the initial interviews, no
    prototypes were available to present to subjects.
  • Our aim was therefore not to test core usability
    concerns but rather to derive a general
    understanding of user perceptions
  • The interview guide included a brief description
    of the SmartCampus project and a brief
    description of the then hypothetical applications
    being developed for the project. The guide
    presented a brief scenario to illustrate the
    possible uses of each of these hypothetical
    applications.

18
(round 1)- Some sample scenarios and questions,
semi-structured interviews
  • Jane is working on a group project for her
    graduate course in Management. The group has
    been communicating by email but has a number of
    unresolved issues. Its an hour before class,
    and she wonders if they might already be on
    campus.
  • They have all made each other buddies for the
    Campus Explorer System, so when she looks, she
    sees that two out of three are on campus already-
    one in the Library and one in the parking lot.
    She Instant Messages them and they agree to meet
    in Starbucks.
  • After talking for a half hour, they have a
    question for the professor Jane checks and he is
    visibly in his office, so they go to talk to him.
    By the time class starts they have been able to
    improve their plans a lot.

19
(Questions following the scenario)
  • Anticipated use - Do you think you would like to
    use the Active Campus Explorer? (If yes, what do
    you think you would use it for? If not, why not?
    )
  • If yes Follow-up/ probes
  • What kinds of people do you imagine you would be
    willing to make a buddy who could track your
    location on campus?

20
Concerns--
  • When you think about the Campus Explorer buddy
    locator system, what kinds of reactions and
    concerns come to mind?
  • (Follow up with many probes on each of these and
    finally anything else?)
  • PLACE probes
  • Are there places on campus where you would not
    like your exact location to be known, even to
    your buddies?
  • TIMES probes
  • Are there times of the day or week when you
    think you would want to turn off this tracking
    system, or that it should be turned off for the
    whole campus?

21
Round one results
  • Anticipated use of SmartCampus
  • No. of Subjects ()
  • CampusWiki - Yes 48 (73.8) No 8 (12.3) Not sure 6
    (9.2) N/A 3 (4.6)
  • SmartCampus Explorer 68
  • CampusMesh 40

22
Coding of Anticipated Benefits

  • Check campus events (26)
  • Exchange information (13)
  • Check crowdedness of places (10)
  • Explorer
  • Find people on campus (30)
  • Increase communication channels (5)
  • Campus Mesh
  • Social networking (16)
  • Make friends (8)
  • Identify people (7)

23
Leading Concerns
  • SmartCampus Explorer
  • Privacy (37)Interruption (7) Stalking (7)
    Personal security (5) Tracking by (unauthorized)
    others ( 5)
  • CampusWiki
  • Validity of data (22) Privacy (10)Absence of
    moderation (8) Overload of irrelevant information
    (4)Slander and negative comments (4)
  • CampusMesh
  • Privacy (10) Intrusiveness (9) Validity of data
    (9) Loss of control (8)

24
Privacy concerns
  • Big brother (6)
  • Identity theft (5)
  • Personal information collection (5)
  • Mugging (3)
  • Different levels of information disclosure (3)
  • Stalking (2)

25
Examples of big brother quotes
  • I dont want a computer knowing everything, and
    I dont know whos looking at this stuff.
    someone else that you didnt want knowing where
    you are, asks your friend who knows where you
    are. (male junior)
  • Well, first of all, being tracked all the time
    and knowing where everyone is. Thats a little
    bit of invasion of privacy. (Female Freshman)
  • but something out there is still monitoring
    where you are. So yes, I would feel a little
    creeped out or angry if I ever, ever discover
    that that was being used in any unintended
    way. (Hispanic grad student)

26
Conclusions
  • Even though most prospective users express
    privacy concerns, they nevertheless say they will
    use this type of system.
  • Similar results have been found for the use of
    social networking systems with personal
    profiling, such as Facebook and MySpace.
