The Spring Breaks R Us social networking subsys- tem requires an intuitive and engaging user-interface design for mobile devices. But the social networking subsystem can also play an important role in resort security. For example, each resort could use traveler location, interests, activities, and likesall of which are available through the applicationto monitor the well-being of travelers staying at the resort. Most spring break travelers are young, and their parents are concerned about their safetyparticularly at isolated resorts in foreign countries. SBRU and the participat- ing resorts could keep track of where travelers are and who they are near, monitor messages about activities and parties, and anticipate crowded conditions or vulnerable travelers wandering off-site. Alerts could notify security if conditions veer away from normal or if messages indicate there are problems. For example, if the pool is overcrowded, some action can be taken. If messages refer to places off-site that are known to be dangerous, security can make an extra patrol. Although many people find this use of private infor- mation objectionable, othersparticularly parents find it essential.

Imagine resort security with a large, wide-screen monitor tracking traveler activities. Design a main screen that includes multiple locations, paths and roads, traveler location and status, messages traveling from traveler to traveler, and other features that secu- rity should monitor. Create a storyboard that shows an example of a pop-up alert and a menu of options that security might select after an alert. Should you also show security the staff members locations and status? How about clicking security staff members to send them a message? How about clicking a location to turn up the lights or to close a security gate? Be creative as you think through the design possibilities. You should include four or five screen layouts for the storyboard.
