HCI Introduction 2013. Spring
HCI ? Human Computer Interaction
Why HCI ? Bad Design costs lives, money, and time Ex) Bank site : 10min x 50,000,000 Pretty good is pretty easy ‘The Design of Every Things’, Don Norman
Prototyping grounds communication gain insight bigger than real product strategy for efficiently dealing with things that are hard to predict
The rights of a Prototype should not be required to be complete should be easy to change gets to retire
What Do Prototype Prototype? Feel : What might it look like? Implementation : what might it work like? Role : what might the experience be like? “ The best way to have a good idea is to have lots of ideas” - Linus Pauling (chemist)

Evaluating designs How can we measure success? 1) Usability studies: Common and straightforward way to find and fix interface bugs I existing software 2) Surveys & Focus group Meeting Quick way to gather feedback from lots & lots of users
Evaluating designs 3) Feedback from Experts Peer critique Heuristic evaluation 4) Comparative Experiments Help menu 5) Participant Observation Good way of gaining insights by discovering people’s actual practices, as opposed to self-report 6) Simulation & Formal Models Input tech.
Issues to Consider Reliability / Precision Generalization Realism Comparison Work Involved
