What is engineering psychology? 5

Engineering Psychology

Engineering psychology is the science of human behavior and capability, applied to the design and operation of systems and technology.

What is interaction design? 6

Interaction Design (IxD)

Design of the behavior of products, environments, systems, and services so that they are useful, usable and delightful.

Design and Business 13

Creating a course requires interaction design. 14

Discover Deliver Design

Client Designer HKU would like an elective for students in the Psychology Department that introduces the field of interaction design. I’ve created a course that hopefully meets their goals. And now I’m presenting this lecture.

Things teachers should care about...

Who are the students? What are their goals? What perceptions and biases do the students have?

“Design Thinker”

32

“The central tenet of design thinking, isn't one of aesthetic or utility, but of empathy and human observation. Be empathetic... Try to understand what people really value. Doing that will lay the foundation for more intuitive designs.” David Kelley IDEO & Institute of Design, Stanford University

Love your experiments.

33

Joy is the engine of growth. Exploit the liberty in casting your work as beautiful experiments, iterations, attempts, trials, and errors. Take the long view and allow yourself the fun of failure every day. Bruce Mau Bruce Mau Design, Incomplete Manifesto for Growth

Interaction Design and the Overall User Experience 34

Machine’s should be friendly to humans. 35

Hi! Hey.

Machines should communicate in human terms. 36

Machines should help reduce human error. 37

Design Models

Rational Action-centric

43

Rational Design Model

44

The design process is plan-driven. The design process is understood in terms of a discrete sequence of stages. Designers attempt to optimize a design candidate for known constraints and

• bjectives.

Action-Centric Model

The design process is improvised. No universal sequence of stages is apparent – analysis, design and implementation are contemporary and inextricably linked. Designers use creativity and emotion to generate design candidates.

Two Design Processes

Goal-directed Design Human-centered Design
