Abstract
Human-computer interaction (HCI) design is the modern and advanced research area that is focused on human or user and system or device interactions. HCI is concerned with new and advanced approaches to a system that must be reliable and efficient to the user. HCI design required a longer and critical development process, methods or framework that passes through various evaluation phases. Due to an inadequacy of user-centered and value sensitive design for a system or device, numerous designs and artifacts do not draw attention to the user. On the other hand, user perception of advanced and new devices are not acceptable and perceived, if not reliable or facile to them. HCI comprises several methods, principles, and criteria which are followed during the development of interaction design. Even then, at times the evolved new and advanced interaction artifacts are unable to reach the user attraction. The HCI methodologies promote the researchers as well as designers to form and develop new and advanced innovations whereas, interaction design term plays a significant role in the design process. In this paper, the key concern is to analyze the conventional design method, Activity Theory (AT) and consider the principles of HCI and bring in a conceptual extended AT model to develop the appearance of Human-computer interaction design.
