  2. 0BHumanComputerInteraction:AnOverview • WhatisHumanComputerInteraction(HCI)? • ImportanceofHCI • GoodandPoorDesignExamples • WhatandWhoareinvolvedinHCIdesign?

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

WhatisHCI? • concernedwiththedesign,evaluation&implementationofinteractivecomputersystemsforhumanuse&withthestudyofmajorphenomenasurroundingthem”(1992) • Dix:HCIisstudyofpeople,computertechnologyandthesetheseinfluenceeach determinehow wecanmakemoreusablebypeople”(1998) • Carroll: HCI is thestudy andpracticeofusability.Itis aboutunderstandingandcreatingsoftwareandothertechnologythatpeoplewillwanttouse,willbeabletouse,andwillfindeffectivewhenused.”(2002)

  5. WhyHCI? • Now,computersarecheap andusedby non-technicalpeople(differentbackgrounds,needs,knowledge,skills) • Computerandsoftwaremanufacturershavenoticedtheimportanceofmakingcomputers“user-friendly”:easytouse,savepeopletime,etc. • Howtoachieve“user-friendliness”in computerdesign?

  6. HCIScope • Use&Context:Findapplicationareasforcomputers • Human : Study psychological & physiologicalaspects e.g.,study howauserlearnstouseanewproduct,studyhumantypingspeed • Computer: Hardware&softwareoffered e.g.,input&outputdevices, speed, interactionstyles,computergraphics • Development: Design,implementation&evaluation
