Transition Diagram − Set of nodes and links that can be displayed in text, link frequency, state diagram, etc. The objective of this chapter is to learn all the aspects of design and development of interactive systems, which are now an important part of our lives. The scientific evaluation of the stated usability parameters as per the user’s requirements, competences, prospects, safety and satisfaction is known as usability testing. For the past couple of years, majority IT companies in India are hiring designers for HCI related activities. These tools may reduce the cost and time involved in experimentation by lowering the chances of failed experimentation. The test planning stage represents the need to review long–lead-timetest planning activities. Web applications, games, embedded devices, etc., are all a part of this system, which has become an integral part of our lives. Even multi-national companies started hiring for HCI from India as Indian designers have proven their capabilities in architectural, visual and interaction designs. 6. Satisfaction − The ease of the work system to its users. Let us now discuss on some major components of this system. Designers may ask incorrect questions to users. The word "usability" also refers to methods for improving ease-of-use during the design process. Th E.g., Microsoft Visio, Visual Studio .Net, etc. The interactive system design shows that every phase depends on each other to serve the purpose of designing and product creation. In common usage, the phrase is broadly defined to include all aspects of system design that affect system use (Smith, 1982a). The methodical study on the interaction between people, products, and environment based on experimental assessment. Such rules affect application architecture and library design.
