Bluetooth Beats is a physical turntable emulator. With a DJ Hero controller, a Wiimote, OSCulator, and PureData, Bluetooth Beats gives anyone the ability to manipulate and scratch songs like a DJ without the need for expensive, professional equipment.
The purpose of the official DJ Hero game is to reproduce the experience of being an actual DJ. For example, in the game, when a user places their finger on the 'vinyl' and pulls in a certain direction it makes a scratch sound. These actions take place in a controlled environment, with set songs and scratch points, where a user follows prompts provided by the game - scoring points for reproducing the sounds in the game.
