Definition of interaction design
interaction design is about defining the behaviour of artefacts, environments, and systems (for example, products).
Jodi Forlizzi & Robert Reimann

A simple explanation of interaction design by myself:
Interaction design is to design interactive process between user and product based on investigation of user behavior, so that it could help user to achieve their goal easier and better.

The squint test (squint your eyes to check design work in blur)
There is three main parts in these players: play part, list part, recommendation part. It is obviously that the right one is more distinct.
Although the left player mimicked windows media player, it didn’t catch the distinct point.
Interaction design includes not only mini details, but also whole process such as flow chart, and translates it into wire flame.

Interaction design methodsCard Sortingit is tool to observe how users categorize information, which could help you organize the website information.-------------------------------------------------Contextual InterviewsIt is a user research method that applies ethnographic observation and one-on-one interviewing to understand the task procedures that users follow to reach their goals.-------------------------------------------------Focus GroupsA Moderator facilitates a small group of participants for discussion, so that you could understand users’ ideas, attitudes and needs.-------------------------------------------------Heuristic Evaluation Heuristic evaluation involves having a small set of evaluators examine the interface and judge its compliance with recognized usability principles.
Individual InterviewsIndividual interviews typically refer to talking with one user at a time , which c can give you a deep understanding of the people who come to your site. -------------------------------------------------- Parallel DesignSeveral people create an initial design from the same set of requirements. This process helps to generate many different, diverse ideas and ensures that the best ideas from each design are integrated into the final concept.--------------------------------------------------PersonasA persona is a fictional person who represents a major user group for your website site, which could help the team focus on the users’ goals and needs.--------------------------------------------------PrototypingIt is a draft version of a Web site, which could be used for testing before investing time and money into development .
Interaction design methods
SurveysIt is a way to conduct online or paper questionnaires among users to collect their responses of the web site.--------------------------------------------------Task AnalysisIt means learning about specific task users must do to meet those goals and what steps they take to accomplish those tasks.--------------------------------------------------Usability TestingUsability testing is a technique used to evaluate a product by testing it with representative users. In the test, these users will try to complete typical tasks while observers watch, listen and takes notes.--------------------------------------------------Use Cases Use cases describe the interaction between a primary actor (the initiator of the action) and the system itself.--------------------------------------------------
