  3. WhatisHCI? Thestudyofbridgebetweenthem,whichincludes • Observationofinteractionsbetweenpeople&computers,e.g.,FindexaminationpapersviaourlibraryWeb • Analysisoftheinvolvedinteractions,e.g.,Areallthestepsinvolvedarenecessary? • Humanconsequencesafterinteractingwithcomputers,e.g.,Cantheuserperformhistask?Doesheenjoyworkingwiththecomputer?
