“Design Thinker” “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 32
Love your experiments. 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 33
Interaction Design Design of the behavior of products, environments, systems, and services so that they are useful, usable and delightful. Behavior Interaction Designers Content Form Information Architects Industrial Designers Copywriters Graphic Designers Animators Sound designers 34 Interaction Design and the Overall User Experience
Hi! Hey. Machine’s should be friendly to humans. 35
Machines should communicate in human terms. 36
Machines should help reduce human error. 37
Three levels of design aspiration Accommodate users’ cognitive limitations Address users’ needs and goals Influence people’s behavior and tendencies 38
Interaction designers accommodate people’s cognitive limitations. 39

Design Models Rational Action-centric 43
Rational Design Model 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 objectives. 44
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. 45
Two Design Processes Goal-directed Design Human-centered Design 46
Goal-Directed Design Requirements Framework Refinement Research Modeling Support definition of user, definition of of behaviors, users and the users and development business, and design structure form, and domain use context needs technical needs and flow content 47
Goal To be at work. Task To drive to work.
Human-centered Design 49
