Interactive design is the relationship between products and systems that any user interacts with. It defines how the behavior will occur between the system and the response to its user(s).
The steps of developing good interaction design are very similar to designing a product.
1. Research
2. Research analysis and concept generation
3. Alternative design and evaluation.
4. Prototyping and usability testing
5. Implementation
6. System testing
Throughout the whole design process, the designer must take into consideration the emotional influences and responses that the end user will produce. There are many factors that contribute to a successful design by emotionally engaging the user in positive thoughts and responses which include fonts, sizes, layout and colour.
Socially, interative design can be seen in devices that we so frequently have contact with, including mobile phones and computers (and the interfaces) as well as constantly improving how we interact with other technological devices.
