HCI stands for Human Centered Interaction‚ which means the interaction between users (people) and computers. This includes different areas of study such as psychology‚ fine arts‚ computer science. The whole concept revolves around better interaction between machines and users‚ including the design‚ evaluation‚ the grasp and of course the implementation of interactive communication system for better human use. HCI is also referred to as man–machine interaction (MMI) or computer–human interaction (CHI)

some Health Care Information Systems (HCIS) do succeed‚ the majority are likely to fail in some way because of conception – reality gaps as described by the ITPOSMO model. The paper attempts to provide an understanding and model of why HCIS succeed or fail‚ and with general guidance on how to avoid HCIS failure. The paper argues that the main reason which determines the failure or success is the extent of change between ‘where we are now’ and ‘where the HCIS wants to get us’ or dimension of change

interact with computer? The interactions of computer and humans are known as human-computer-interface (HCI). Human-computer-interface (HCI) developers and engineers goals are to improve the user’s overall experience. This can be accomplished by creating a lasting memory for the end user and a good feeling of using the technology known as haptic technology. HUMAN COMPUTER INTERFACE What is HCI? HCI is the study on how to better improve the interaction between

Introduction to HCI What is HCI? The study of how people interact with computers and to what extent computers are or are not developed for successful interaction with human beings. •What is HCI? “Human-computer interaction is a discipline concerned with the design‚ evaluation and implementation of interactive computing systems for human use and with the study of major phenomena surrounding them” (ACM SIGCHI definition of HCI). •Creating usable systems (1) • •HCI investigates interaction

Computer Interaction (HCI) on Society Human Computer Interaction has improved the usability/user friendliness for many different types of technology enabling society to interact with technology devices with ease. Without the improved usability/user friendliness of technology‚ it would inaccessible to people who are computer illiterate. People will use/purchase the types of technology they find easiest and most convenient to use. Some types of technology/devices that use HCI and have impacted
