Introduction-week1
Human Computer Interaction
The joy of good design often becomes invisible
The Power of Prototyping
Focus on goals in evolving your design
The rights of a prototype
- Should not be required to be complete
- should be easy to change
- Gets to retire
Prototypes answer questions, like...
- How might it look like?
- What might the experience be?
The best way to have a good idea is to have lots of ideas.

Evaluating Designs
Usability studies are a common and straightforward way to find and fix interface bugs in existing software.
Controlled experiments can limit the real-world applicability when they are done in a contrived (人为的) setting.
Surveys are a quick way to gather feedback from lots and lots of users.
Feedback from Experts
- peer Critique
- Dogfooding
- Heuristic Evaluation（启发式）
comparative experiments and Participant Observation is a good way of gaining insights by discovering people's actual practices, as opposed to self-report.
Simulation & Formal Models
Issues to Consider
- Reliability/Precision
- Generalizability
- Realism
- Comparison
- Work Involved
The Birth of HCI
-
Vannevar Bush In the 1940s, wrote of how future technologies could augment human intellect.
Key to the memes idea was effective user interfaces for information
storage and retrieval -
Grace Hopper invented the compiler.
The Graphical User Interface
The mouse and Hypertext -
Doug Engelbart invented the mouse.
-
Alan Kay at Xerox PARC, prototyped the Dynabook, and created many important ideas in the graphical user interface
