HCIL Symposium: Day 1

02.06.2006.

Note:

Due to the large amount of content, I will be updating this a bit more to fill in the blanks of the later sessions of the day. Check back for more info.

Welcome

Jenny Preece opened the symposium discusssing the College of Information Science and its collaboration with the HCIL. Dr. Preece indicated that the team is very interested in social, collaborative technologies and processes.

Benjamin Bederson continued the welcome, discussing the interdisciplinary nature of the group (psychology, information science, computer science). Web 2.0, he indicated, is succeeding because there us a greater focus on issues of usability, democracy, and user-centric design.

Creativity Support Tools: A Grand Challenge for HCI

  • Software must support the creative process
  • A new research direction is emerging
  • Dramatically improved creativity support tools are possible
  • Multi-dimensional in-depth long-term case-studies (MILCs)
  • Guidelines for design are emerging

Session 1: Visual Interfaces

  1. Improving the search experience by organizing Web search results with meaningful and stable categories
    • Video shown to display a search engine that shows a results list but also has a left-hand column that organizes search results into meaningful category overview
    • types:
      • textual
      • graphical
      • stable
      • clustering

  2. Supporting Library Scholars with Data Mining and Visual Interfaces
    • Data mining interfaces can be designed to be accessible to literary scholars
    • Visual interface for data mining
      • Accessible
      • Provocational
    • www.noraproject.org
    • (Reminds me of Mood Project)
  3. Network Visualization to Support Exploration of Supreme Court Decision Patterns
    • Analyzed 2000+ court cases (data sets)
    • Ability to visually restrict or expand district information
    • www.cs.umd.edu/hcil/nvss
  4. Balancing Systematic and Flexible Exploration of Social Networks
    • Example: National Consortium for the Study of Terrorism (START)
    • Compiled a dataset of allknown terrorist attacks (currently 70,000 over 27 years)
    • “Hot” and “Cold” colors emphasize geographic locations that are either volatile or peaceful
    • www.cs.umd.edu/hcil/socialaction
  5. NetLens: Iterative Exploration of Content-Actor Network Data
    • There are challenges to network visualization
    • NetLens freely downloadable and used with any database?
    • Heuristic evaluation by NIST
      • Navigation is easy and required little training
      • UI widgets are understood by most people
      • The metaphor for the visualization is understandable
    • www.cs.umd.edu/hcil/netlens

Session 2: Public Access

  1. When Children are Digital Librarians: Reader Response to the International Children’s Digital Library (ICDL)
    • Look at the role of children’s emotion, response, and book recommendations
    • Fantastic search model for children (click image to sort by book jacket color, book size, etc.)
    • www.childrenslibrary.org
  2. Children Sharing Stories with ICDL Communities: A Pilot Study in Mexico and Maryland
    • Develop communities for children to discuss books across cultures
    • Identity representation was a big hit
      • Girls drew pictures of themselves
      • Boys drew pictures of things they enjoy (e.g., soccer ball, monster, etc.)
    • www.childrenslibrary.org
  3. Collaborative Educational Technology to Enhance Grade School Field Trips
    • Tangible Flags- physical colored flag with embedded RFID tag
    • Students place flags at physical locations and use tablet pcs to draw what they see near the flag
    • Students use the tablet pc to read the RFID of a flag to load information that a previous student may have added
    • Students can collaboratively add notes and edits to the drawing using their own tablet pc
    • Although collaborative, only a few students at a time can collaborate
  4. The Promise and Perils of New Voting Technologies
    • Remember the Florida voting problems?
    • Team reviewed the usability and accuracy of a variety of voting methods/systems
    • Touch Screens proved to be the most usable and accurate
    • www.cs.umd.edu/~bederson/voting

Session 3: Interaction and Devices

  1. Thumb Movement: Designing for One-Handed Use of Small Devices
    • Analyzed mobile devices -how easily can you interact with them using one hand?
    • Looked at various cellphone styles and various PDA styles
    • Created molds of these devices just to represent the shape and size of the device (removed existing buttons and controls)
    • Added LED diodes to record thumb movements
    • Determined that side to side movement isbest – avoid repetitive diagonal movements
    • Determined that for larger devices (PDAs), strive for interaction targets toward the center of the device (e.g., Palm Treo 700w)
    • www.cs.umd.edu/hcil/mobile/
  2. Eye Tracking as Implicit Feedback for Improving Search Results
    • Eye movement indicates visual interest
    • Visual interest = cognitive interest
    • Tracked users focus on paragraphs of text usinglarge cumbersome head unit
    • In the future, will use an eye tracking device that is embedded in a computer monitor – Tobii
