CS147 Social Mobile CS147 Social Mobile Presentation Transcript

  • CS147 Social / Mobile Mor Naaman, Yahoo! Mirjana Spasojevic, Nokia
  • Learning Goals
    • Learn the basic types of social software and recognize important aspects of social design
    • Understand the role of mobile in social software and social interaction
  • Outline
    • What is Social Software?
    • Social Software Aspects
    • Design in Social Software
    • Mobile Social
  • Social Software 101
    • What is social software?
    • It’s all here
  • Tom Coates
    • “ Social Software can be loosely defined as software which supports, extends, or derives added value from, human social behavior”
        • http://www.plasticbag.org/
    • No longer person-machine…
    • … but an interconnected
    • network
  • Social Software is Not New, Really
    • Doug Englebart, Mother of all demos
    • 1968
  • Types/Examples
    • - Communicators
    • Email, Email lists, UNIX talk, Buddy Lists/Instant Messenger, IRC/CHAT ,
    • - Group, Collaboration
    • Usenet, Web Boards, Forums, Wikipedia?, Blogs, Wikis, Writely, del.icio.us, citeUlike,
    • - Attention, Awareness
    • MySpace, Flickr, YouTube?, Yelp, MoSoSo,, FaceBook, 43things, ESP Game, FaceBook
    • - Games, Role Play
    • MUDs, MOOs, Graphical Worlds, MMORPGs, WoW, Second Life
    • - Social Tasks
    • Friendster, LinkedIn
    • -Recommendation
    • Amazon, Ebay, Last.fm
  • Or just ask the people
    • http://del.icio.us/popular/socialsoftware
  • A few ways to think about it
    • Communication
    • Collaboration
    • Awareness
    Engagement Content
  • To Borrow from CSCW Co-present Remote Synchronous Asynchronous
  • Identity Dimensions
    • Identity
      • (virtual, based on real, personal)
    • Interact with
      • (strangers - known others - friends)
    • One-to-one, one-to-many, many-to-many
  • Social Design
    • What does it mean?
  • Tom Coates
    • “ Design is not about purely the visual layer. Design in social software is about creating functional social environments that fulfill user needs, extend or enhance the social or collaborative abilities of the people within them, are clear and easy to use and avoid falling foul of trolls, griefers and internecine conflicts”
          • http://www.plasticbag.org/archives/2006/11/thoughts_around_socia/
  • MySpace Screenshot
  • Case Study: Flickr
    • Distribution of “number of photos in account”
    Number of photos Number of users 6 12 18 … Huh??
  • Flickr Tagging Interface
  • Case Study - Flickr
    • Nobody tags other people’s content
    • Why?
    Not collected Not identified Not prominent In user’s account As coming from the tagger In the interface, as “opinion” Not aggregated Can’t “vote” on tag/item pair
  • “Social Engineering”
    • FaceBook - photos annotated with username.
    • FaceBook - show latest friend’s activity
    • What if MySpace comments appeared at the end of the page?
    Think “community”, not “individual”
  • What happened here?
    • Salient features changed
      • Not just about the physical interaction
      • It’s about the social interaction
  • Incentives
    • People respond to incentives, want to be polite, want to share, want to socialize, and act differently if they feel they're in a group
    • Some thoughts here:
      • HT06, Tagging, Taxonomy, Flickr, Article, ToRead
  • Metcalfe’s Law, Reed’s
    • Metcalfe’s Law
      • The value of the network is proportional to the square of the number of nodes
      • N(N-1)/2
    • Reed’s Law
      • The utility of a network where groups are allowed is exponential in the number of nodes
      • 2^N - N - 1
  • Meanwhile, In Mobile…
    • Still very much one-to-one, rich, engaged: talking on phone
    • Moving towards lightweight, less involved
    Engagement Content
  • Meanwhile, In Mobile… Co-present Remote Synchronous Asynchronous
  • What is Mobile?
    • Keitai, in Japan - not “mobile”, not “cellular”
    • Keitai: “something you carry with you”
    • “ A keitai is not so much about new technical capability or freedom of motion but about a snug and intimate technosocial tathering, a personal device supporting communications that are constant, lightweight and mundane presence in everyday life” (Mimi Ito)
  • People use their mobile phones while on the go…
  • … but they also use them when they are not mobile
  • How and Why People Use Camera Phones
    • Summer 2004: Why the low rate of capture-and-send?
    • Little data on what people really do with camera phones (the whole range of activities)
    • Study Goal: investigate emerging behaviours of camera phone users in US and UK
    • Key research questions:
      • Range and diversity of use
      • Characteristics and context of use, image life-cycle
  • Taxonomy of Reasons for Capture Analysis of 295 captured images from 34 subjects: 278 photos, 17 videos Coded 1-2 intended uses Discussed here Mutual task 12 (4%) Mutual experience 103 (35%) Social co-present absent Remote task 22 (8%) Absent friends/family 63 (21%) Personal task 29 (10%) Functional Personal reflection 120 (41%) Affective Individual
  • Social affective : absent friends and family
    • Reaching people absent at moment of capture, then or later
    • Keeping in touch, riddling, teasing, storytelling, …
    • From sharing in excitement of now to “by the way…”
    • Predominantly images of specific things (60%); half as many with people, scenes
    • Sent in the moment (27%) or later(16%); shown on phone (38%)
    • Strong use of common ground
    “ This was a telepresence - she could feel like she is here to see it." “ One of my work colleagues said … I haven't seen your little cherub for a while.”
  • Social functional: remote task
    • Support for shared tasks
    • Reminders, records, samples, evidence, experimenting, …
    • Specific objects, copies of writing, images, …
    • Sent in the moment (40%) or later (15%); shown on the phone (25%)
    • Importance of timeliness
  • Observations
    • Digital “touch” – sharing images with absent people
    • Bringing into the experience, timeliness important
      • Sending in the moment – 1/3 of shared images
      • … or sharing later, typically face-to-face
    • Image content and personal common ground
      • Enhancing common ground, affirming relationship
      • … fluid sharing, interpreting for others
    • General obstacles: cost, complexity, quality, not enough people to receive
  • Implications for image sharing
    • Integration into larger dialogues
      • Always connected, switch between channels (e.g. IM, MMS)
      • Integrated with text, voice; timely delivery
    • Web based forms of sharing
      • Spontaneously chosen subjects; reliance on personal common ground or interpretations
      • Web mechanisms require considerable re-thinking; much progress made in the past two years
    • Full report:
      • T. Kindberg, M. Spasojevic, R. Fleck, A. Sellen
      • How and Why People Use Camera Phones,
      • http://www.hpl.hp.com/techreports/2004/HPL-2004-216.pdf
  • Beyond Personal Communication
    • One-to-one -> many-to-many
    • Communication -> Awareness
  • Communication channels have clear benefits and reflect intent
    • Channel
    Use Example: Intent Benefit Email - Text IM - Text Mobile Phone Call - Voice SMS/Text Message - Text MMS Message - image and text Blog/MySpace Post - image and text
    • Writing to family
    • Work communications

    • 1:1, 1: many
    • Recipient can respond at their convenience.
    • IM with friends while at work

    • Invasive for receiver
    • Social dynamics of face-to-face conversation.
    • Text a friend when you arrive at a destination
    • Running late.
    • I want to let them know I am here, but I don’t want to bother them.
    • Mostly 1:1
    • Less invasive
    • Quick
    • Look where I am!
    • Should I buy this?
    • I want to share something with more than words.
    • Mostly 1:1
