Development in digital technology and video technology significantly contributes to increases of the utilization of video sources in a variety of performances. At the same time, the necessity to promptly control and change the video gets higher, especially in live performance. In these circumstances, if the performer could control the video depending on actions without need of direct contact to the device, live video performance will be much faster and more convenient. In other cases, DJ who carries out mixing music in club and DJ party would like to take a role of visual performer as well, or control background video in realtime corresponding to the music being played. In these cases, gesture recognition based non-contact interface could be advantageous over a traditional way of touching or contacting the device directly. To this end, the starting point of our study is to devise the user interface that enables a live video production making use of hand gesture recognition device. However, the hand gesture recognition based user interface might cause unintended wrong recognition due to similarity of device-controlling hand gesture and normal hand gesture. To prevent this, we introduce the gesture-recognition mode switcher using pre-gesture.
