Page History

This first screen would be the screen that the user first sees upon opening a file set. At the top, there is a title bar indicating that the user is in analysis mode. There is a flat very lightly colored gray scale map of the area in question (pictured here is the northern two-thirds of Africa). Similarly to Google Maps, the user can drag around the map with the mouse, as well as zoom in and out using the controls on the left. In the top left there is a button that toggles between month and year (other option can maybe be added) and corresponds to the slider on the bottom. For instance, if you are in month-mode, the slider will move through monthly averages of the data from January to December while in yearly mode, it would move from 2000-2012 or something of that nature. On the top right of the screen, there is a button titled "Layers" which will generate a drop-down list upon click that will contain all the possible data sets the user can add to the map. The large arrow on the right of the screen will shift the user into the next mode (which for lack of a better name is referred to as the edit mode in this design).

If the user clicks the "layers" menu and selects an option, "demographics" (here written as population) for instance, the first that will occur is that a box with the name "demographics" and a small "x" will appear to the left of the "layers" menu. In addition, the data set will be added to the map. Color and specific shading can of course be determined later, but let's assume for this design that demographics is represented by the color red. In that case, a light red area representing the entire year's population area will appear on the map, and a bright, solid red will indicate the area covered in that
specific month. There would be a similar outcome in yearly mode as well.

On this screen, we can see more details in Analysis mode, in terms of overlaying data sets and popping open the "layers" menu. It becomes more apparent as to how the user would use the program to visualize the exact set of data he'd like to analyze.

When the user is done setting the data, he can hit the arrow on the right side of the screen to move forward. The first thing to occur after this action occurs is that the title bar will change to "edit" mode (here written as "edit hotspots"), and a pop up window will appear as the background fades out in some way indicating inactivity. The window will indicate some backend sort of magic occurring (not the focus of this class, so we will just assume it exists)

This last frame is the "edit" mode screen that the user can actually interact with. Note that now the arrow is on the left side of the screen, indicating the way which the user can return to the analysis screen (by clicking or perhaps with a keyboard shortcut). Note that the layers menu at the top along with the current layers being displayed are still visible. What is new, however, are the circular forms on the map. Each of these circles would represent a new wifi tower as generated by the magic backend algorithm. There are also sliders (three sliders pictures, although more or less might be appropriate as needed for the parameters the users desire) in which the user can adjust things like total cost, quantity of towers, average strength of towers, power used, etc. These sliders would have an immediate effect on the representations of the wifi towers on the map, in that using the sliders would change the size of the circles appropriately. In addition, it would be possible to manipulate each individual tower by clicking on it. Clicking on a circle would display the information pertaining to that particular tower (i.e. location, strength, wattage, and whatever else is relevant). It would also be possible to drag it to change the range or move the circle itself. After the user is finished, they can save the map using the save button at the bottom right. It would also be ideal (even though this is not pictured) to add a share button and feature to the map on this screen.
