This paper proposes an experimental wearable controller for live video performances called the VJacket. The VJacket can be worn by the performer or visual artist (VJ) to control video effects and transitions, trigger clips or scratch frames with the output of the integrated sensor system. The sensors detect body movements like bending, touching or hitting, and can send OpenSoundControl or MIDI messages wirelessly to the VJ program of your choice. The VJacket brings the rhythmic movement of dance to computer interaction, so the VJ won't have to fumble for knobs and buttons or look at the screen to be sure he's clicking on the right thing - he will be free to control the video using his body movements alone.
