Human Computer Interaction

• Efficiency is an important principle in HCI, focusing on designing interfaces that allow users to accomplish tasks quickly and with minimal effort.
• HCI (human-computer interaction) is the study of how people interact with computers and to what extent computers are or are not developed for successful interaction with human beings.
• Human-computer interaction looks at how people interact with computers and is a community of people studying and practicing user experience design, user research, software development, and more.
• The close integration of research and practice makes the field of human-computer interaction extremely unique.
• UX and interaction designers represent the craft side of HCI and share this responsibility with other practitioners.
• UX was created within HCI and has since expanded its influence in the design world.
• A usable system is easy to learn, easy to remember how to use, effective, efficient, safe, and enjoyable to use.
• Usability is only one part of HCI but has been one of the main goals.
• HCI has contributed to the development of guidelines and standards that support designers.
• HCI has also developed methods of evaluation that help us to evaluate the usability of a given product/system (and other aspects of the user experience).
• HCI uses mathematical models to predict users’ performance with a system, such as Fitt’s law to predict mouse movement time, or models that predict search time or mental effort.
• HCI investigates new interaction paradigms or new ways of integrating technology in our daily lives, such as smart clothes, touch displays, VR/AR, Voice-based interfaces.
• Apple Lisa, released in 1981.
• Sutherland’s PhD thesis also defined the terms “objects” and “instance”.
• The first mouse was developed by Engelbard at Stanford in 1963.
• Xerox Alto, released in 1973.
• Xerox Star, released in 1981.
• Apple Mac, released in 1984.
• Windows 2.0, released in 1987.
• World Wide Web, released in 1990.
• Konrad Zuse invented the world’s first programmable computer in 1941 and this remained the only working computer in Europe up to 1951.
• VisiCalc, released in 1979, was one of the first spreadsheet programs.
• Windows 1.0, released in 1985.
• Windows 3.0, released in 1990.
• SketchPad by Ivan Sutherland at MIT in 1963 introduced the concept of direct manipulation of objects, paving the way for the Graphical User Interface.
• SketchPad is the first object-oriented programming system.
• ENIAC, the first electronic numerical integrator and computer in the US, was constructed in 1943 and the first programmers of the ENIAC were six women, known as the “Refrigerator Ladies”.
• Ivan Sutherland’s SketchPad, developed at MIT in 1963, is considered a significant contribution to HCI.
• Designers craft technologies to enhance the human experience during Wave 3, encouraging people to interact with technology on their own terms, and to support their individual development and aspirations.
• Social Media have influenced how we stay in touch with each other and how find new friends and lovers during Wave 3.
• Massive increase in productivity during Wave 3 due to HCI's understanding of how to speed up input and reduce its complexity.
• 3D Printing pancakes using FDM during Wave 3.
• Virtual Reality during Wave 3.
• Touch screen: direct interaction with objects during Wave 3.
• During Wave 3, value-driven design takes the lead in engaging communities and designing for sustainable change.
• Voice control: for some people the only way to interact with computers during Wave 3.
• Computers can now be used as an every-moment partner during Wave 3.
• Qualities of pleasure, enjoyment, play, and exploration become central to design during Wave 3.
• Games, more than entertainment, can be used as social and even productive tools during Wave 3.
• Augmented Reality during Wave 3.
