Unit 1 CC7 Human Computer Interaction Laurie Lynne F. Aspiras  History of Human Computer Interaction Four Major Components in HCI Fail Designing Donald A. Norman principles Six concepts in designing  Multidisciplinary field of study on the design of computer technology and interaction between humans and computers Concerned with the physical, psychological, and theoretical aspects of the processes Has since expanded to cover almost all forms of information technology design  Human Computer Interaction(HCI) is an area of research and practice that emerged in the late 1970s and early 1980s, initially as an area in Computer Science. HCI has expanded rapidly and steadily for three decades, attracting professionals from many other disciplines and incorporating diverse concepts and approaches.  1970s- The rise of the Personal Computer. The broad project of cognitive science, which incorporated cognitive psychology, artificial intelligence, linguistics, cognitive anthropology, and the philosophy of mind, had formed at the end of the 1970s.  1980s- Graphical User Interface (GUI). Graphical User Interface (GUI) is the interface that is designed for the easier understanding of the users of the computers. Before GUI, there was a command prompt by which command was given to the computers. GUI started the graphical interface which is easy to use, understand, visualize, and it improved the working environment.  1990s- The Internet and Collaborative works. The Internet started journey in 1990s. So, communications among people became easier. In the consequence of this, many new technologies arrived for better communication.  2000s- Mobile Computing and Beyond. Mobile phones, PDA (Personal Development Assistance), and Smart Phones are ruling the present world. They offer a wide range of services to the people such as sms, mms, multimedia, games, email, internet, chatting, video conference, GPS etc.  Now a days the HCI is used in the area of Cognitive Science. With the help of the Internet, medical facilities can be provided remotely. Different interactive interfaces are designed those can be used for the cognitive rehabilitations.  Human – The Who Computer – The Where Interaction – The What Context – The How  Human Also known as the user / end-user Limited in their capacity to process information Has important implications for design Focuses on who the HCI is for  Computer Focuses on where the HCI is found Comprises various elements, each of which affects the user of the system Input devices Output display Virtual reality systems Various displays (physical controls, haptic dieback, sensors) Paper output and input Memory Processing  Interaction Interaction models help us to understand what is going on in the interaction between user and system Address the translations between what the user wants and what the system does Focuses on what the HCI is  Context Also known as paradigms Examples of effective strategies for building interactive systems to design usable interactive systems Focuses on how the HCI will be formed Ranges from the introduction of timesharing computers, through the web, to ubiquitous and context aware computing  Visibility Feedback Constraints Mapping Consistency Affordance  Visibility  Feedback  Constraints  Mapping  Consistency  Affordance  Balance Contrast Proximity Repetition White Space Alignment  Balance  Contrast  Proximity  Repetition  White Space  Alignment
