Brazil Project proposal

I will create an interface that will be controlling sounds with one hand. I will use a sensor to check the distance from the sensor to the hand this will control the music the farther or closer your hand is would have a different result on the music. Then I will have another sensor for your other hand that will control a visual set.  This will be done in the same fashion as the first sensor.  I want the sensors to be able to recognize hand gestures so your hand does not have to be hovered in the same spot the whole time.  I want the possibility to be open to add more than two sensors I want the user to have more freedom then just hovering over one sensor, so it does not get boring as easily.  If possible I would like to do a sensor for the DMX lights. The visual set will also be partially connected with the music. Im not fully set on what i want to put the sensors in but i am thinking of putting them each in a square or a disk that can resemble a dj work area.
