Interface

00

A boundary across which two independent systems meet and act on or communicate with each other.

What is the industrial designer’s responsibility?

Physical interface itself

A Humanized InterfaceLessons learned so far:• Don’t replace humans • Don’t replicate humans• Reflect human behavior.

Three qualities of the human interface (Christopher Fahey, IXDA 2010)– Sentience– Intimacy– Personality

Cognition Models00

• Human information processing• Embodied cognition• Distributed cognition• Internal & external cognition…• More to explore

Gap between design and evaluation methods

Cost of not evaluating

Costs of …• Fixing• Customer, Technical and Web Support• Upgrades/patches• Training• Lost competitive advantage• Damage to company reputation

28© 2011 Cheryl Zhenyu Qian & Steve Visser, Purdue University

What methods are there?• Laboratory tests

requires human subjects that act as end users

– Experimental methodologies• highly controlled observations and measurements to

answer very specific questions i.e., hypothesis testing

– Usability testing• mostly qualitative, less controlled observations of users

performing tasks

29© 2011 Cheryl Zhenyu Qian & Steve Visser, Purdue University

What methods are there?• Interface inspection

done by interface professionals, no end users necessary

– Usability heuristics• several experts analyze an

interface against a handful of principles

– Walkthroughs• experts and others analyze an

interface by considering what a user would have to do a step at a time while performing their task

30© 2011 Cheryl Zhenyu Qian & Steve Visser, Purdue University

What methods are there?• Field studies

requires established end users in their work context

– Ethnography• field worker immerses themselves in a

culture to understand what that culture is doing

– Contextual inquiry• interview methodology that gains

knowledge of what people do in their real-world context

31© 2011 Cheryl Zhenyu Qian & Steve Visser, Purdue University

What methods are there?

• Self reportingrequires established or potential end users

– interviews– questionnaires– surveys

Identified Many ProblemsFor example, for CP• Impossible to make universal product creation since no two CP patients are exactly the same.• If wake up during the midnight, it is very hard to adjust position and fall back to sleep• Lack of resources to organize series of training• Lack of adequate information resources for patients who are over age of 18.• Expensive products and treatments• Eager to regain some form of freedom: from human aides, of movement, of social interaction.

Review the process

• Design research to identify problems

• Brainstorming to generate alternatives

• Create digital and physical prototypes

• Cognitive consideration to enforce designs

• Evaluation to ensure quality
