Abstract—The Human-computer interaction (HCI) is the study of how people design, implement, and use interactive computer systems and how computers affect individuals, organizations, and society. This encompasses not only ease of use but also new interaction techniques for supporting user tasks, providing better access to information, and creating more powerful forms of communication. It involves input and output devices and the assistive devices interaction techniques that use them; how information is presented and requested; how the computer’s actions are controlled and monitored; all forms of help, documentation, and training; the tools used to design, build, test, and evaluate user interfaces; and the processes that developers follow when creating Interfaces. HCI in the large is an interdisciplinary area. It is emerging as a specialty concern within several disciplines, each with different emphases: computer science (application design and engineering of human interfaces), psychology (the application of theories of cognitive processes and the empirical analysis of user behavior), sociology and anthropology (interactions between technology, work, and organization), and industrial design (interactive products). Keyword- HCI, anthropology, assistive technology devices and interactive products.

The concept of human–computer interaction (HCI) was first presented by a group of professionals at the Association for Computing Machinery’s Special Interest Group on Computer–Human Interaction Conference in 1992. 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. Computer vision has been an active area of research for more than three decades. A quick review of the field reveals that image processing and pattern recognition has been tremendously successful in terms of delivering operational systems. This paper explains project applying Human computer interface (HCI) knowledge and techniques, such as accessibility and usability, to help people with cerebral palsy or other severe disabilities carry out specific tasks with computer. The goals of HCI are to produce usable and safe systems, as well as functional systems. In order to produce computer systems with good usability, developers must attempt to understand the factors that determine how people use technology develop tools and techniques to enable building suitable systems achieve efficient, effective, and safe interaction put people first. The organization of a computer vision system is highly application dependent. These systems open new paradigms in HCI and allow us to innovate ways of interaction that can benefit people with severe disabilities like cerebral palsy. According with the United Cerebral Palsy (UCP), Cerebral palsy describes a group of disorders of the development of movement and posture causing activity limitation that are attributed to non-progressive disturbances that occurred in the developing fetal or infant brain. The motor disorders of cerebral palsy are often accompanied by disturbances of sensation, cognition, communication, perception and/or behavior, and/or by a seizure disorder.

It is an undisputable fact that the computer, which was once only operated by experts during the years it was first introduced and was produced in small numbers, is now an indispensable part of human existence. Therefore it gains more and more importance that the computers and the software running on them i.e. the interfaces can be effectively and efficiently used by everyone and should be further improved to meet that need.HCI (human-computer interaction) is the study of how people interact with computers. Human–computer interaction (HCI) is the study, planning and design of the interaction between people...
