People prefer computers that conform to them rather than conforming to computers. A Natural natural and easy process in learning how to use a device is crucially important in a product. If the learning process is too complex or take takes too much time; , the users won’t want to use the product and will search for alternatives for it. The purpose of Natural user interface is to make the user feel like a natural. User-friendliness and natural input are of key importance in this area. Rather than reading through manual , software devices are designed in such a way as to allow the user to discover the functions of the product, through minimal experimentation. In this sense the technology teaches us how to use it through interaction. Simply exploring the functions of a cellphone or an iPad may serve as an example of this, as do cars that can park themselves.  For instance, the technology now exists on the market that allows a computer to park a car by sensing the surrounding area and acting accordingly. The luxury car giant Lexus currently markets such a model and this serves as an excellent example of easy natural user interface. Many north Americans can drive a car, but giving control to a computer to move the car while the person is actually in it, in other words trusting the computer to safely park the car without damage is a strong example of the level of trust that people have placed in technology and how far the paradigm shift has come. In terms of ease of use in this interface , no special training is required to make use of this feature and it is presumed that any driver will be able to make use of this feature in a comfortable way since the car is on the market. This is a good example of a natural user interface since the only skills needed are the ability to drive in the first place a have only the causal acceptance and awareness of technology usage that most people have these days.
