**3. Challenges in developing intelligent user Interface**

The Intelligent Agent that functions behind the IUI has at least the following characteristics [5].


The performance of an intelligent component may be sensible to failure leading to inappropriate interpretations of commands leading to action and appropriate reaction as Intelligent processing is often relatively difficult for users to predict, understand, and control a demanding situation online. If the demand is bit more elongated depending on relatively extensive information about the users, the intelligent systems may raise certain types of privacy and security risks as private data may not be easy due to security point.

Major challenge to such a situation is evaluating the order of performance of the algorithms used in design and execution of the Intelligent Interfaces. This involves Smart speech processing for talking to the smart human user, Image processing for viewing the activities of the smart human user and Natural Language Processing for understanding the language of a human who is not aware of the language the system is dealing with. As such system will be immediate use of the elderly people and small children. Besides these the factor that influences more is the environment which, controls the functioning of the Intelligent User Interfaces mostly as it changes its features like facilities with respect to user interaction accordingly.

To have Smart Eyes, Ears and Skin (touch) for the IUI are the foremost devices to be developed to enable it to act as the IUI in true sense. Besides the sensor based applications are a basic need for such a system. Presently sensors are operational through Internet. Most of the activities can be controlled by such devices called Internet of Things or IOT. These are the smallest unit in IUI for the largest objective satisfaction. The most important point here to use such devices in IUI is the Security in using IOT as it is internet controlled Cyber intervention are very much expected [11].
