tailieunhanh - Lecture Human computer interaction: Lecture 17 - Professor Dr. Sajjad Mohsin

Upon completion of the course, students will be able to: Explain human factors of HCI including human body physical abilities, ergonomics, accessibility, health issues, cognitive load and psychology; explain hardware factors of HCI including different input and output devices . keyboard, mouse, and touchscreen. understand different key elements from which user interfaces are constructed;. | Lecture 17 cognitive models Today’s Outline Today we will cover goal and task hierarchies Linguistic physical and device architectural What is cognitive science? Cognitive science is the science of mind and behavior. It is different from psychology! Cognitive Science Theme “Cognitive” Of or pertaining to cognition, or to the action or process of knowing. Understanding knowledge acquisition and use is the key to understanding the mind. So what is cognitive science? Cognitive science is a scientific study of the mind with special emphasis on the use and acquisition of knowledge and information. Implications An inter-disciplinary approach – Many scientific disciplines contribute to cognitive science. A computational approach – Explain information processing in terms of neural computations. Definition 1 "the study of intelligence and intelligent systems, with particular reference to intelligent behavior as computation" (Simon & Kaplan, 1989) Simon, H. A. & C. A. Kaplan, "Foundations of cognitive science", in Posner, . (ed.) 1989, Foundations of Cognitive Science, MIT Press, Cambridge MA. Definition 2 Cognitive science refers to the interdisciplinary study of the acquisition and use of knowledge. It includes as contributing disciplines: artificial intelligence, psychology, linguistics, philosophy, anthropology, neuroscience, and education. Cognitive science grew out of three developments: the invention of computers and the attempts to design programs that could do the kinds of tasks that humans do; the development of information processing psychology where the goal was to specify the internal processing involved in perception, language, memory, and thought; and the development of the theory of generative grammar and related offshoots in linguistics Definition 2 (con.) Cognitive science was a synthesis concerned with the kinds of knowledge that underlie human cognition, the details of human cognitive processing, and the computational modeling of those | Lecture 17 cognitive models Today’s Outline Today we will cover goal and task hierarchies Linguistic physical and device architectural What is cognitive science?
