Human Computer Interaction Human

The user of a computer program, computerized device, or other information technology artifact

Computer The physical device, artifact, or hardware that

runs the program

Interaction The communication between the human and the

computer

Why Care about the human?

Human Computer Interaction A discipline concerned with the

of interactive computing systems for human users

design implementation

evaluation

Slide: Saul Greenberg

User Centered Design

process figure: http://www.yucentrik.ca/en/expertise-2/tools/

Our focus:1. Methods for

understanding user needs

2. Methods for evaluating interfaces and techniques with users

3. Theories/models of human performance

NOT DESIGN(3160 in the Fall for user

interface design, prototyping, discount usability evaluation)

User Interface Design HCI

CSCI 3160: UI DesignIterative Design

Design architecture of system Draw UI sketches/task scenarios Prototyping Evaluate with users (primarily

formative) Redesign Implement Prototypes and evaluate

(heuristics, cognitive walkthroughs) Design Considerations

Graphic output/input Errors Design and layout Task

Software E.g., GUI toolkits,

CSCI 4163 – HCIUnderstand users

Learn about their needs, tasks, etc.

understand how users do something to help inform design decisions

Critically understand different experimental approaches to understand and evaluate systems

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 interactionTo develop an appreciation for experimental HCI research and how it can refine the theories/modelsTo be able to apply these techniques to do basic HCI research To learn about User Experience as a career path
