This course provides an introduction to and overview of the field of human-computer interaction (HCI) to give students an understanding of how the study of human-computer interaction affects the design of interactive systems and improves students awareness of the issues that determine the usability of an interactive computer system. Credit Hours: (3,0) HUMAN COMPUTER INTERACTION – LECTURE 1 3 Goals Implication of human computer interaction understand human computer characteristics of HCI Introduce suitable usability engineering lifecycle models Designing user-interfaces through prototyping techniques Evaluate user-interfaces Books Course Book: “Human Computer Interaction” by - ALAN DIX JANET FINLAY 3 ed. available in soft form. Reference Books: “Interaction Design Beyond Human-Computer Interaction” by Preece, Jenny” “About Face3 The Essentials Of Interaction Design” by Alan Cooper “HCI beyond the GUI” by Philip Kortum HUMAN COMPUTER INTERACTION – LECTURE 1 5 HCI – A Formal Definition “Human-Computer Interaction is a discipline concerned with the design, evaluation and implementation of interactive computing systems for human use and with the study of major phenomena surrounding them” -ACM/IEEE Role of Computers Computer invasion has started Traditional notion of computers becoming obsolete Computers are everywhere Computers will annoy, infuriate, and even kill HUMAN COMPUTER INTERACTION – LECTURE71 Advantages of computers Help solving complex problems Increase efficiencies Make human lives easy and convenient Drawbacks of computer Unable to understand humans Infuriate them And even kill them Examples from Current Era Computer in Alarm Clock Computer in Camera Computer in Car Computer in Warship Computer in Airplane Computer in Airplane No indication of wrong fix selection Communication was precise and exacting while still being tragically wrong Not the pilots fault: ◦Computer told pilot he was tracking precisely to the location he had selected Computer Behavior They tell but do not inform. They may guide with precision but they do not guide where we want to go. So who is to be blamed?
