Rubato Prototype README: Our prototype is built using Proto.io. Operating instructions: Navigate to https://gjacuzzi.proto.io/share/?id=916da12d-327a-453d-b6ee-d2a7abee5204&v=1 to launch the simulation, and proceed with the login screen displayed on our prototype. The prototype is interactive via your computer mouse. LimitationsL Due to the absence of conditional logic and limitations in available components in Proto.io, the upvoting functionality is not implemented, as well as the ability to switch between songs, change volume, and actually update the playlist with new interactive additions. Finally, the default session configuration regardless of creation setting parameters is to have a public playlist, to show user controls, and to enable voting of the songs. Wizard of Oz Techniques: 1) When a user wants to add a song, we will tell them that the song is added to the playlist. 2) When a user wants to play a song, we will play the song ourselves. The prototype cannot play songs.
