1. An airline company is designing a kiosk that can display destination weather information in public locations. The kiosk will feature a touch screen so users can select a city by pointing on a map. a. Give one reason why a touch screen is an effective device for this application. b. Provide one difference between direct-control and indirect-control pointing devices. c. Name a task when one type of direct-control device /indirect-control pointing device is a more appropriate device than the other. 2. Some designers suggest that speech recognition should be used in an airline telephone menu system. This would allow users to interact with the system by speaking instead of pressing buttons on the dial pad. a. Give two arguments for the proposal. b. For the above scenario, give two arguments against the proposal. c. Provide one example of a application of context-aware computing that would meet user needs. 3. The use of mobile devices has been increasing rapidly over the past few years. These devices typically feature much smaller screens than desktop computers. a. Provide two strategies of how you could successfully implement an interface to browse through a user's set of digital photographs on a small device. b. Provide an example when speech generation would serve the user's need better than a visual screen. c. Provide two limitations the user would have by using the speech generator. 4. Take a position on whether you feel user interfaces for work will remain isolated or if they will become more collaborative. a. Present at least one evidence to support your argument. b. Provide one idea how an interface designer can protect users of a collaborative interface from hostile or malicious behavior. c. Provide two examples of collaboration and social media participation, including crossover characteristics

5. Face-to-face Encounters and Collabaration a. Differentiate the roles of face-to-face encounters and collaborative interfaces. b. Provide one limitation and benefit of face-to-face encounters and collaborative interfaces. c. Provide one reason why collaborative interfaces, such as email, are much more popular than others, such as video-conferencing

6. Distributed and Collabarative Interfaces a. Provide an example of an Asynchronous Distributed Interface. b. Provide one pro and con of such a system when compared to an interface that is Synchronous Distributed. c. Provide one reason of how collaborative interfaces can improve or harm teamwork.
