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

Human Computer Interaction

A discipline concerned with the
implementation
design
evaluation

of interactive computing systems for human users
Slide: Saul Greenberg
User Centered Design

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)

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
