P2- Fundamental Principles of HCI design Human computer interaction can be very influential on our society‚ economy and culture. However for this to happen it has to be of an adequate level‚ a level capable of making an impact. To achieve this‚ developers of HCI platforms ensure that they stick to the fundamental principles of HCI design. In the first part of this report I will be illustrating the fundamental principles of design. FUNDAMENTALS The following are the fundamental principles of Human

We investigate the relational fundamental models which can reveal the common ground of HCI technology and analyze the literature for solving the interaction difficulties of the persons with motor and visual disabilities respectively. A number of drawbacks and suggestions are made for future research on HCI technology for the disabled people. Keywords: Survey‚ Human computer interaction

Chaebols helped South Korea to problems related to development of HCI with the support from government. Chaebols are similar to conglomerates that are large companies that operate in different sectors that allow the corporations to support their own businesses through the expansion in business area.

What is Human Computer Interaction? Human–computer Interaction (HCI) involves the study‚ planning‚ and design of the interaction between people (users) and computers. It is often regarded as the intersection of computer science‚ behavioral sciences‚ design and several other fields of study. The term was popularized by Card‚ Moran‚ and Newell in their seminal 1983 book‚ "The Psychology of Human-Computer Interaction"‚ although the authors first used the term in 1980‚ and the first known use was in

One developing technology in recent years‚ Human-Computer Interaction (HCI) involved the study‚ planning‚ and design of the interaction between users and computers (Dillon‚ 2002). Research suggests that because HCI studies a human and a machine interactively‚ that is draws from supporting knowledge on both the machine and on the human aspect of the technology (Dillon‚ 2002).

I will also define Human-Computer Interaction (HCI) . I will be utilizing the 5W+H (What‚ Where‚ When‚ Who‚ Why and How) analytical format . I’m going to discuss the factors that makes HCI a everyday usage. Definition Human–computer Interaction (HCI) involves the study‚ planning‚ and design of the interaction between people (users) and
