Chapter one talks about how important design is for any type of product. There are several design principles that must be considered before undergoing any type of product development. The most common principles are: visibility, feedback, constraints, consistency, and affordance. Visibility is the idea that something should be visually appealing and recognizable. Feedback is about instant gratification. People need to know that what they are trying to do is either working or not. Constraints is the concept of determining ways of restricting the kinds of user interaction that can take place at a given moment. Consistency is the idea of keeping similar processes uniform. Affordance means that the user should be able to use the product without difficulties.
This chapter was very interesting because it gave real world examples that most of us can relate too. For instance, the example of usability and appeal about the TiVo remote. Another example was the menus in Adobe Photoshop showing logical constraining. This example showing the shaded area indicating deactivated options really helped me understand this concept. I like that this book is actually up to date with technology and the world today. Most of the books I have read for previous classes are out of date and do not relate to the students.
