Chapter 1 ID

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 Most of the books I have read for previous classes are out of date and do not relate to the students.

    I agree with many of the things you have mentioned, especially concerning the extreme importance of a detailed design for any type of product or service. The principles that you discussed were defined very well and the descriptions were covered in full.

    The fact that the book is so new makes it great to relate current issues as well as experience with current product successes and failures. It makes the class and readings much more interesting when discussing up-to-date products and services that have relevance to all of us. Everyone now knows, if a product or service isn’t relevant is shouldn’t be designed, prototyped, or produced.

    It’s good to hear that you are finding a personal relationship to the examples covered in the book. (You too, Jason). There may be a reason for this. The tools and technologies that have come to be widely known and used are either 1) indispensable, 2) useful and have value for us. The indispensable technologies include technologies such as OnCourse or Windows (for the most part) that we accept because they allow us to do certain things. We accept them with all of their faults. The useful and valuable technologies such as TiVo or Facebook. Have considered what we will find entertaining and what we will find value in. These are the technologies that should come to our minds first for either good or bad designs, because we have to deal with them all the time.

    As for the summary, in your next response please try to capture the overall theme of the chapter a little better. You focused in on one section (and you did this well), but there were other parts that you did not really mention.
