Human Computer Interaction
Human
Computer
The user of a computer program, computerized device, or other information technology artifact
The physical device, artifact, or hardware that runs the program
Interaction
The communication between the human and the computer
Why Care about the human?
Moore’s Law

Slide idea by Bill Buxton
Slide: Saul Greenberg
Human Computer Interaction
A discipline concerned with the
implementation
design
evaluation
of interactive computing systems for human users Slide: Saul Greenberg
User Centered Design 1. 2.
3.
Our focus: Methods for understanding user needs Methods for evaluating interfaces and techniques with users Theories/models of human performance
NOT DESIGN (3160 in the Fall for user interface design, prototyping, discount usability evaluation) process figure: http://www.yucentrik.ca/en/expertise-2/tools/
User Interface Design HCI CSCI 3160: UI Design
Iterative Design
Design architecture of system
Draw UI sketches/task scenarios
Prototyping
Evaluate with users (primarily formative)
Redesign
Implement Prototypes and evaluate (heuristics, cognitive walkthroughs)
CSCI 4163 – HCI Understand
Critically
understand different experimental approaches to understand and evaluate systems
Design Considerations
Graphic output/input
Errors
Design and layout
Task
Software
E.g., GUI toolkits,
users Learn about their needs, tasks, etc. understand how users do something to help inform design decisions
When to use which approach (advantages and disadvantages)
Analyze
results and use these to develop guidelines
Quantitative and qualitative data
Evaluate
high fidelity prototypes, interaction techniques, etc. (often summative, comparative)
Course goals
To understand strengths and weaknesses of different experimental methods in HCI To learn about how theories/human models of human performance impact interaction To develop an appreciation for experimental HCI research and how it can refine the theories/models To be able to apply these techniques to do basic HCI research To learn about User Experience as a career path
Homework for Thursday’s class
