  1. Human Computer InteractionCSC 4730-100User System InterfaceCSC 8570-001 Class Meeting 7 October 9, 2012

  2. 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

  3. 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

  4. Gesture Analysis The Mac and iPad revisited Looking at the table

  5. 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

  6. Car Key Analysis (2) Buttons: All are momentary contact • Panic • Door unlock • Door lock • Trunk open

  7. 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.

  8. 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

  9. 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.

  10. Another Formal Model: PIE 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

  11. Course planning • 10/16 – Fall break • 10/22 (Monday) – Choice of research article for presentation with area and bibliographic information due, via email • 10/23 – Interface design exercise: specs • 10/30– Interface design exercise: team meetings • Preliminary interface design report due at end of class • Research project Progress Report 1 due • 11/6 – Topics to be determined • Final interface design report due • 11/13 – No class • 11/20– Paper presentations: User Experience (UX) • Research project Progress Report 2 due

  12. Course planning (2) • 11/27 – Paper presentations: Intelligent user interfaces (IUI) • Draft research report, part 1, due • 12/4 – Paper presentations: Interface personalization (IP) • Draft research report, part 2, due • 12/11 – Research Project Presentations • Final research report due • 12/18 – Final Exam • Research project poster abstract and design due

  13. Research Project • IRB forms (due now) • Progress reports (PR 1 due 10/30; PR 2 due 11/20) • Report drafts (Intro sections due 11/27; Results sections due 12/4) • Final written report (Due 12/11) • Oral report (Given 12/11) • Poster abstract and design (Due 12/18)

  14. To Do • Submit presentation area and article for approval by Monday, October 22. Send area and bibliographic citation by email.
