Images - DJ Interface

Description

For the home page, we opted for a simple look. Since login was not part of the previous design process,
we simply mocked it up and implemented it. While testing internally, we found that it would be good to give
the user feedback immediately about the validity of their input.

Heuristic Evaluation:

Added a log-in and sign in form page to introduce the app (Consistency and Standards)

There are basically four main sections here. The upper left shows the previous song. During user testing we
found that this was not needed on the initial login so we removed it until a song was played. At that point, we
added in both the currently playing song and feedback from how the crowd rated the song.

Removed album title from previous winner (Recognition Over Recall)
Added DJ feedback graph to show user input (System and Real World)
Changed "Search" to "Search by song name" (Consistency and Standards)
User Test

Made bars show up on DJ feedback when vote count was 0 |

When we initially tested this page, we didn't get a lot of useful information. After the user testing, however,
the djs we tested on said that they would like this pane to be able to slide away. If we were to continue further,
we would simply replace the begin voting pane with this and allow the user to cycle between these two views.

Increased space between the top section and the voting pane (Flexibility and Minimal Design) |

This is the same screen as before but now we are looking at the search menu as well. For the search bar, we
got feedback that the user would like to click on the entire row. This was actually an implementation detail as
the autocomplete library would fire it's handler before our custom tags. To get around this, we simple disabled
the default handler.

Everybody pretty much liked our charts. Just changed the text to match the rest of the dj interface.

During the user test, we got feedback that we should also visualize the voting information here. Currently, we
display data about the songs that were played but not about the user votes that we processed.

Added certain genre related information tabs to the graph charts that adapt to the DJ's interests (Skills) |

Images - Listener Interface	Description
	When a user initially opens the application, they see this default home page. They are prompted to "submit a dj code." This screen was created after the entire app was completed. It's simply a less detailed version of the home screen that we previously developed (explained in the next image). Initially, this screen kept the rating buttons, but after the user testing period, we decided to remove them. Also, to make it easier for users, we made the DJ code case insensitive.
	After submitting a valid "DJ code," information begins to populate the app. The user can see the name of the song currently playing and "rate" it either up or down. There is also a "tweet" button that would allow the listener to tweet about the event. There is also a navigation bar to let the user move between the other screens. The main goal for this page was to make it as simple as possible. After the heuristic evaluations, we decided to change "rate this song" to "rate this party" in an attempt to give users a better understanding of what exactly they were rating. After submitting the dj code, we initially left it on the screen, but after doing the user tests, we decided to remove it.
	In this screen, the user sees the list of songs that have been played. When the user clicks on a song (i.e. after clicking on "Lights"), the selection expands, showing the album cover, the artist, and the genre. Initially, we planned on presenting as much information on the song as possible. However, after the heuristic evaluations, we decided to remove most of the information (like year produced, record label, etc.).
	This is the voting screen. When the DJ selects songs for the listeners to vote from, they are shown here. Each voting option shows the name of the song, the artist, and the current number of votes.
