Special Issue of Infor On Human-Computer Interaction

User Interface (UI) is the part of the system that acts as an intermediately between the user and system facilitating the user to interact with the system in an efficient manner. The user interface is everything the end user comes into contact with while using the system physically, perceptually, and conceptually. To the end user, the user interface is the system itself. Hence, usability of a system remains one of the most important quality attribute in determining the total quality of any software system. The challenge of user-interface design is to construct a natural dialog sequence that allows the user and computer to exchange the messages required to carry out a particular task. The user interfaces do vary from system to system and user to user. In this paper we have identified the different issues in designing efficient user interface. All these issues are discussed at length with suitable example.

The user interface is arguably the most important element of a computer-based system or product. If the interface is poorly designed, the user's ability to tap the computational power of an application may be severely hindered. In fact, a weak interface may cause an otherwise well-designed and solidly implemented application to fail. Three important principles guide the design of effective user interfaces: (1) place the user in control, (2) reduce the user's memory load, and (3) make the interface consistent. To achieve an interface that abides by these principles, an organized design process must be conducted. User interface design begins with the identification of user, task, and environmental requirements. Task analysis is a design activity that defines user tasks and actions using either an elaborative or object-oriented approach. Once tasks have been identified, user scenarios are created and analyzed to define a set of interface objects and actions. This provides a basis for the creation of screen layout that depicts graphical design and placement of icons, definition of descriptive screen text, specification and titling for windows, and specification of major and minor menu items. Design issues such as response time, command and action structure, error handling, and help facilities are considered as the design model is refined. A variety of implementation tools are used to build a prototype for evaluation by the user. The user interface is the window into the software. In many cases, the interface molds a user's perception of the quality of the system. If the "window" is smudged, wavy, or broken, the user may reject an otherwise powerful computer-based system.

Enhancing user experience (UX) in interactive systems requires effective human-computer interaction (HCI). The relationship between people and computers has grown in significance as technology progresses, having an impact on many areas of our life. The main ideas and tactics used in HCI to enhance the user experience in interactive systems are examined in this abstract. Understanding the capabilities and constraints of both humans and computers forms the basis of HCI. HCI researchers and designers may develop interactive systems that complement users' mental models and cognitive processes by researching human behavior, cognition, and psychology. Additionally, taking into account the features of the computer system, such as its responsiveness, processing capacity, and interface design, enables the development of systems that are more userfriendly and effective. As a result, the discipline of human-computer interaction works to improve the user experience in interactive systems. Researchers and designers in the field of human-computer interaction (HCI) can produce interactive systems that are simple, effective, entertaining, and satisfying for users by comprehending human capabilities, applying user-centered design principles, utilizing interactive techniques and interfaces, integrating multimodal interfaces, and embracing emerging technologies. The continued development of HCI will continue to influence and enhance how people use computers, enhancing user experiences and creating new opportunities for interactive systems in the future.

Advanced techniques for developing intelligent user interface attempt to resolve a number of needs that occur during the time dealing with human-computer interaction finding adaptive communication method for the user. Techniques dealing with natural language systems knowledge gesticulations, knowledge of photography and multimedia interfaces. Considering therefore artificial intelligence techniques of this kind, then the intelligent interface agents are computerized anthropomorphic beings that enable automation of a problem, we believe that in the future there will be a changed approach moving from the interface of adaptive current in a multimedia interface that would demonstrate an intelligent interface and stronger. New research in the field of modern computer science and information technology is impossible to think without the use of artificial intelligence, where as a fundamental pillar presented the development of intelligent systems. Recently much has been invested in the creation of Intelligent User Interfaces applications for different purposes to facilitate the use of information technology achievements, trends and simplified relationships or interactions between users and machines. To achieve these investment opportunities to create which Intelligent User Interfaces simplifies work and enables optimal use of computer and other equipment from different walks of life. A particular benefit of the Intelligent User Interfaces certainly people with disabilities (impaired vision(blind), hearing). The answer lies in the use of intelligent interfaces, in addition to conventional units and peripheral inputs to a system and applied modern methods of interaction, such as speech, movement, gesticulations etc..
