Q

Figure 2. search results

When you hit the submit button, the system returns the paragraphs in the book that contain the words together with the chapter and page numbers of the paragraph (see figure 2). That is, it behaves very like a web search but with paragraphs rather than web pages..

Figure 1. search window

Q2: How did the team manage the value for users here?

Q1: After reading the case Study, what do you understand by HCI term “value”?

Notice you get value if you don't have the book but use the web site and even more value if you have both!

However, if you don't have the book, every time you use the search you see references to where in the book you would learn more - it says 'buy me' every time!

If, on the other hand you don’t use the book, the search gives some information about the terms, a bit like an online encyclopedia of HCI. So it is still worth book marking.

Imagine you have the book already. When you want to find anything in the book you can use the search page. It tells you where to look in the book with enough context to let you know which reference is the most appropriate.
