Human Computer Interaction (HCI)?

What is Human Computer Interaction (HCI) ? The term human–computer interactionhas only been in widespread use since the early 1980s, but has its roots in more established disciplines. Systematic study of human performance began in earnest at the beginning of the last century in factories, with an emphasis on manual tasks. The Second World War provided the impetus for studying the interaction between humans and machines, as each side strove to produce more effective weapons systems. This led to a wave of interest in the area among researchers, and the formation of the Ergonomics Research Society in 1949. Traditionally, ergonomists have been concerned primarily with the physical characteristics of machines and systems, and how these affect…show more content…
We are interested in answering a particular question. How do principles and methods from each of these contributing dis-ciplines in HCI help us to design better systems ? In this we must be pragmatists rather than theorists: we want to know how to apply the theory to the problem rather than just acquire a deep understanding of the theory. Our goal, then, is to be multi-disciplinary but practical. We concentrate particularly on computer science, psychology and cognitive science as core subjects, and on their application to design; other disciplines are consulted to provide input where…show more content…
We are certainly even further from having a unified theory of experience than of task. The question of whether HCI, or more importantly the design of interactive sys-tems and the user interface in particular, is a science or a craft discipline is an inter-esting one. Does it involve artistic skill and fortuitous insight or reasoned methodical science ? Here we can draw an analogy with architecture. The most impressive struc-tures, the most beautiful buildings, the innovative and imaginative creations that provide aesthetic pleasure, all require inventive inspiration in design and a sense of artistry, and in this sense the discipline is a craft. However, these structures also have to be able to stand up to fulfill their purpose successfully, and to be able to do this the architect has to use science. So it is for HCI: beautiful and/or novel interfaces are artistically pleasing and capable of fulfilling the tasks required – a marriage of art and science into a successful whole. We want to reuse lessons learned from the past about how to achieve good results and avoid bad ones. For this we require both craft and science. Innovative ideas lead to more usable systems, but in order to maximize the potential benefit from the ideas, we need to understand not only that they work, but how and why they

The current evolution in computer technology in recent years has facilitated the development of real-time computer human interaction. Examples can be found, particularly in biometrics and human computer interaction, as the information contained in faces needs to be analyzed for systems to react accordingly (Yang, 2009). Faces first need to be located and registered to

    Abstract—Facial Expression Recognition refers to the classification of facial features in one of the basic emotions: happiness, sadness, fear, disgust, surprise, anger and neutral. It is performed by means of feature extraction. Principle Component Analysis is a technique among the most common feature extraction technique used in Facial Expression Recognition. In this paper, a Facial Expression Recognition System for human’s expression identification using Principle Component Analysis with City-Block

Face detection is an electronic computer technology that limits the locations and sizes of earthborn face in arbitrary conception. It detects only facial features and ignores the background. Face detection is a novel approach through which we can extract the facial features from a human body. [11] Face recognition system categorizes into two
