The inspiration behind this project came about after experiencing discomfort over long and direct experimentation with mixing songs on a tablet. Current DJ applications for tablets are useful, yet they lack usability. The screen that is already compact in size has to be divided into three sections – two deck units and the mixer unit. It was too small to manipulate and execute professional DJ stunts adequately. Therefore, a device is designed to keep the versatility of the tablet but improve the comfort of the user. Z-JAY allows the user to mix songs and apply effects combining all the necessary DJ equipment (one mixer and two decks) into one integrated system. Basically, It comprises three tablets with touch screen interfaces that act in sync, attached to a system that allows the device to be easily folded. The device is designed such that the user can carry all the essential DJ equipment easily. The possibilities with this device are plenty – just to mention a few, the external deck units can be connected and controlled by the tablet; each of the Z-JAY decks can be easily divided into two, three and four decks using the same mixer, thus allowing up to eight songs to be mixed at the same time; and the user can upload music files directly into the device. Furthermore, Z-JAY ‘s user interface resembles standard DJ equipment (mixer and decks). Therefore, it is easy and intuitive to use – one simply has to touch the screen with his fingers.
