chpater 7&8 Designing the user interface: strategies for effective human-computer interaction (textbook)

1.An airline company is designing a new on-line reservation system. They want to add some direct-manipulation features. For example, they would like customers to click a map to specify the departure cities and the destinations, and to click on the calendar to indicate their schedules. From your point of view, list four benefits and four problems of the new idea compared with their old system, which required the customer to do the job by typing text. 2. Provide three examples of an application where menu selection and form fill-in are more appropriate than a direct-manipulation strategy. 3.Analyze an application you commonly use, like your word processor (Dont pick a Word Processor!), and list the various commands available through keyboard shortcuts (such as CTRL-P to print, F7 for spellcheck, etc.). Decide if these commands are well designed for users.
