“Toto, I don’t think we’re in 2604 anymore.” • Class discussion, participation • HWs/Projects: open-ended • Group project • Student presentations
Textbook • Mary Beth Rosson and John M. Carroll, Usability Engineering: Scenario-Based Development of HCI(required) • Visual C# .NET,Step-by-Step by Sharp&Jaggeror Core Ref by Williams(optional)
The Project • Team-based • Choose topic • Information vizualization • Problem seeking / problem solving • Find users & problem, prototype, interim review presentation, evaluate, revise, final presentation • C# language?
Grading Breakdown • Presentation (hall of fame/shame) 5% • homework (4 x 5%) 20% • Mid term 10% • Design project 50% • Team formation 0% • Requirements 10% • Formative analysis & design 20% • Interim presentation 5% • Prototype implementation 10% • Summative Evaluation 20% • Final presentation 5% • Final implementation 30% • Final 15%
Policies • Homework due in class Thurs. Late = 0 • No early exams, make up by advance arrangement • Signed request with rationale • Reminder of VT Honor Code • Specifically, tests and homeworks are individual • Students with special needs see me ASAP
Adminstrivia • Force-adds and prerequisite forms • CRN is 91680 / 91681 • Prerequisite is CS 2604, REQUIRED • Everyone must complete the forms TODAY • Must attend today • Add decisions by next meeting • Web page (courses.cs.vt.edu/~cs3724) contains syllabus, lecture outlines, assignments, and related materials
HCI ??? • What is it? • Who cares? • Why is it hard? • How does it work? • What will I learn?
1. What is HCI? Human-Computer Interaction
1. What is HCI? • Requirements analysis • Design • Development • Evaluation • of user interfaces for computer systems Human-Computer Interaction
Huh? An example: HomeFinder
The Goal of HCI Usability • People are trying to accomplish their tasks in life. (system independent) • Introduce a system,User Interface should maximize their ability. task person system
2. Who Cares? Everyone, because: • Everything is a User Interface
2. Who Cares? Everyone, because: • Everything is a User Interface • The User Interface is Everything
Florida Cares! • Human error: Who’s fault is it?
Usability is hard • People (users) are all different • People are unpredictable • Design skill isn’t enough • Evaluation with users is required • Designer’s pride • New ways to think, break out of the box
Usability is hard • People (users) are all different • People are unpredictable • Design skill isn’t enough • Evaluation with users is required • Designer’s pride • New ways to think, break out of the box • Programmers stink at Usability
Usability is hard Programmers stink at Usability • don’t think like ‘normal’ people • know the software internals, technology first • enjoy systems more than people • arrogant (my software!)
4. How does it work? Usability Engineering Reqs Analysis Design Evaluate Develop
4. How does it work? Usability Engineering Reqs Analysis Design Evaluate Develop many iterations
5. What will I learn? • Task analysis • Ethnography Reqs Analysis • Usability studies • Controlled experiments Design Evaluate • Activity design • Information design • Interaction design Develop • GUI programming • Widgets, graphics, animation • C#
ANALYZE analysis of stakeholders, field studies claims about current practice Problem scenarios Scenario-Based Design DESIGN Activity scenarios metaphors, information technology, HCI theory, guidelines iterative analysis of usability claims and re-design Information scenarios Interaction scenarios PROTOTYPE & EVALUATE summative evaluation formative evaluation Usability specifications
Grander Goals? • Get angry! • Mental shift: • From system-centered design to user-centered design • Break out of the box
Before you Leave… • Prerequisites form!
