Natural User Interface [NUI] is the medium of interaction between a user and a machine through natural entity (Air) in the form of user's gesture, recognized by the machine using gesture recognition. Gesture Recognition is the detection of human's bodily motion and behavior. Encroachments have been made using advanced cameras, hardware devices like Kinect. Kinect is a motion-sensing device developed by Microsoft for gaming purpose, which now used in the paper to virtualize the input. The paper talks in detail about controlling Domestic Electrical appliances by simple human gestures using Microsoft Kinect. There are systems available to sense human motions for controlling electrical appliances but none of them provide user defined commands and gesture recognition techniques. This system is unique in finding and understanding human gestures.
