CSC 8570 -- USI Class Meeting 5 September 26, 2007
Opening Questions • Who among you has read at least three Harry Potter books? • Who among you is a Sudoku puzzle addict? Or solver? • What is the pattern and hidden meaning in the research team names?
Research Project • Short presentation • One spokesperson • Five minutes • Hypothesis, variables, initial experimental design • PowerPoint • Questions and comments from the audience
Research Teams • Aspen: Allison, Lakshmanan, Tyler • Bailey: Andy, Brian, Franny • Conifer: Chris, Lou, Tim • Durango: Mayur, Prasad • Estes Park: Ashley, Kurt, Sharon
Research Project Issues • Add to bibliography – goal is at least 15 references • Design experiment • Create experimental tools • Complete IRB form • Start writing first two sections • Dates • IRB form finished no later than 10/8 • Progress Report 1 due 10/24
User Goals Based on last week’s discussion and other sources, here’s a list of user goals. Users want systems that: • Are powerful, meaning fast and efficient • Have proper functionality
User Goals (2) • Minimize the possibility for (tragic) errors • Allow easy recovery from misdirected actions • Are easily learned and easily relearned • Fit a cognitive model based on past experience
User Goals (3) • Are easy to maintain, including set up • Are flexible • Stimulate creative problem solving • Are personally satisfying
Understanding Cognitive Dimensions • What are they? • Meaning from name • Meaning from examples • Meaning from individual definitions • How can they be applied? • To notation (in a user interface?) • To representations • To understanding
Generating Examples • Bad interface examples • GUEPs violated • CDs not well exploited
Synthesizing Edge and Blackwell Referring to your concept map: • What is its structure? • What is its shape? • What is its top-level concept?
Relating GUEPs and CDs Match the 14 cognitive dimensions to the 9 GUEPs looking for overlapping and orthogonal ideas. Summarize the results by creating a 14 by 9 array whose cell entries describe the relationship between the ith CD and the jth GUEP
Leave Behind • Concept map of the Edge and Blackwell paper
Next Time • Continue work on research project, completing experimental material and IRB form • Catch up on reading • Button Exercise (see below)
Button Exercise For your assigned two buttons on Windows Explorer, determine for each • Its syntax • Its semantics • Which cognitive dimensions and which GUEPs its behavior exemplifies. Hand in your written report next time.
