important concepts
Important Concepts

As listed on the one-minute survey

  • Research methods for testing usability
  • Requirements specifications for interfaces must be written carefully and followed exactly.
  • GOMS analysis of user interaction
  • Types of measurements available for keyboard entry process
  • Preparing a research experiment
  • Diversity of interfaces; complexity of UI design
  • Keys to creating an excellent interface: innovation, analysis of current UI problems
  • User interface assessment with GUEPs and CDs
  • Specific GUEPS and CDs including Consistency, KISS, Viscosity, Explaining
  • Keystroke level analysis, models (e.g. Fitts’ Law), and notation
  • Semantic and syntactic analysis of widgets
  • Mental models
  • Learning tools: concept maps, research paper reading process
confusions
Confusions
  • Picking essential ideas with final exam in mind
  • The gesture analysis
  • Formal notations for keystroke-level actions
  • Understanding and, especially, use of GUEPs
  • Understanding and, especially, use of CDs
  • Understanding and use of GOMS model
    • GOMS analysis of the table building exercise
  • Identifying good HCI research
  • Statistics for the research project
  • Concept maps
gesture analysis

Car Key Analysis

States:

  • Horn/lights: Beep/Flash vs. No Beep/No Flash
  • Driver’s door: Locked vs. Unlocked
  • Passenger’s doors: Locked vs. Unlocked
  • Trunk: Closed vs. Open

Buttons: All are momentary contact

  • Panic
  • Door unlock
  • Door lock
  • Trunk open
car key analysis 3
Car Key Analysis (3)
  • Are all 16 states possible?
    • Make a list of the possible states.
    • Can the list be decomposed into disjoint lists?
  • Working from the list of possible states
    • How many (state, transition) pairs are there?
    • How many (state, transition) state actions are possible?
    • Create the formal FSM model.
article presentations
Article Presentations
  • Choose one of the threetopic areas (defined below)
  • Find an interesting recent (last 4 years) paper in the area
  • Prepare a 15 minute presentation of the paper
    • The background
    • The experiment
    • The results
    • The critique
    • The relationship to other papers or concepts
article presentations 2

Subject areas:

  • The user experience (UX), its formal study and its relation to interface design.
  • Intelligent user interfaces (IUI) and especially the implementation and evaluation of features.
  • Interface personalization and especially its value on small devices.

To follow along,

  • On your laptop, start the calculator in standard view
  • Start a browser and display a page with a number of links, say www.villanova.edu

Now turn to the PIE Model handout
