Human Computer Interface Introduction – Tutorialspoint



Human Computer Interface (HCI) was formerly referred to as man-machine studies or man-machine interaction. It handles the look, execution and assessment laptop or computer systems and related phenomenon which are for human use.

HCI may be used in most disciplines wherever there’s possible laptop or computer installation. A few of the places that HCI could be implemented with distinctive importance are pointed out below &minus

  • Information Technology &minus For application design and engineering.
  • Psychology &minus For use of theories and analytical purpose.
  • Sociology &minus For interaction between technology and organization.
  • Industrial Design &minus For interactive items like cell phones, micro wave, etc.

The world’s leading organization in HCI is ACM &minus SIGCHI, which means Association for Computer Machinery &minus Special Interest Group on Computer–Human Interaction. SIGCHI defines Information Technology is the core discipline of HCI. In India, it become an interaction proposal, mostly based in the area of Design.


The aim of this subject would be to discover the methods for designing user-friendly interfaces or interactions. Thinking about which, we’ll discover the following &minus

  • Methods to design and assess interactive systems.
  • Methods to reduce design time through cognitive system and task models.
  • Procedures and heuristics for interactive system design.

Historic Evolution

In the initial computers performing batch processing towards the user-centric design, there have been several milestones that are pointed out below &minus

  • Early computer (e.g. ENIAC, 1946) &minus Improvement within the H/W technology introduced massive rise in computing power. People began thinking on innovative ideas.
  • Visual Screen (1950s) &minus SAGE (semi-automatic ground atmosphere), an aura immune system of america used the first form of VDU.
  • Growth and development of the Sketchpad (1962) &minus Ivan Sutherland developed Sketchpad and demonstrated that computer can be used as greater than information systems.
  • Douglas Engelbart introduced the thought of programming toolkits (1963) &minus Smaller sized systems produced bigger systems and components.
  • Introduction of Word Processor, Mouse (1968) &minus Style of NLS (oNLine System).
  • Introduction of pc Dynabook (1970s) &minus Developed smalltalk at Xerox PARC.
  • Home windows and WIMP interfaces &minus Synchronised jobs at one desktop, switching between work and screens, consecutive interaction.
  • The thought of metaphor &minus Xerox star and alto were the very first systems to make use of the idea of metaphors, which brought to spontaneity from the interface.
  • Direct Manipulation created by Ben Shneiderman (1982) &minus First utilized in Apple Macintosh Personal Computer (1984) that reduced the probabilities for syntactic errors.
  • Vannevar Plant introduced Hypertext (1945) &minus To indicate the non-straight line structure of text.
  • Multimodality (late 1980s).
  • Computer Supported Cooperative Work (1990’s) &minus Computer mediated communication.

  • www (1989) &without the first graphical browser (Mosaic) arrived 1993.
  • Ubiquitous Computing &minus Presently probably the most active research area in HCI. Sensor based/context aware computing also referred to as pervasive computing.

Roots of HCI in India

Some ground-breaking Creation and Graphic Communication designers began showing interest in the area of HCI in the late 80s. Others entered the brink by designing program for CD ROM titles. A number of them joined the area by designing for that web by supplying computer trainings.

Despite the fact that India is running behind in offering a recognised course in HCI, you will find designers in India who additionally to creativeness and artistic expression, consider design to become a problem-solving activity and like to operate within an area in which the demand is not met.

This urge for designing has frequently brought them to get involved with innovative fields and obtain the understanding through self-study. Later, when HCI prospects showed up in India, designers adopted techniques from usability assessment, user studies, software prototyping, etc.
