Frodo is a frequent user of this system. He opens up the program automatically to a login screen. He has the option to create a visualization as a guest, or sign in with his username and password. He can then choose the source from which his data is coming from and the type of visualization that will be used. This is very learnable because users are used to login screens, and this one is very similar to many that exist. It is efficient because you only have to go through one screen in order to login. Also in Frodo’s situation the username, password, and most frequent datasets could be autofilled since he is a frequent user.
Once Frodo hits “Go”, he will be brought to the main page interface. This interface allows users to pan through a stack of multiple data maps vertically (similar to cover flow in Mac OS). This main frame contains a general map that can be zoomed and moved, as well as some more specific data information. His data maps include satellite coverage, current Wifi towers, rainfall, and demographics. He wants to quickly find regions that have insufficient coverage and map that against the wifi towers that exist, so he will pan to the “satellite coverage” map, click “overlay”. Now when he pans, that map will stay static and the rest will pan. He will then pan to “current Wifi tower” and hit overlay. Now, both of these maps are overlayed on the main page, as well as more detailed information about both in the bottom right corner.
In order to actually optimize coverage, given the current Wifi towers and adding one or more new towers, Frodo will go to the top panel and check “tower location” and “tower number”, since these are the things he is looking to change. Then he will hit “optimize”, which will give him the option of what he would like to optimize. This is not too learnable, but once someone shows you how to do it, though if the user is experimenting with the software he will probably come across it. It is very efficient in terms of optimization based on certain things. The alternative method, which is widely used now is querying. This is a lot more efficient than that. For safety, there is always the option to cancel, or once you hit go, you exit the optimization with the button in the bottom left. Once the data is optimized, and the new towers are added, Frodo can hover over one of the new data point(s) and see and edit information about it.
Through his project he periodically hits “share” at the bottom right side of the entire screen in order to show his coworker, Samwise, his progress.
