Bilgisayarların günlük hayatımız içerisinde önemli bir rol oynamaya başladığı andan beri, araştırmacılar bu iki varlık arasındaki etkileşimi iyileştirme konusunda çalışmalara odaklanmıştır. Bilgisayar & yazılım sistemlerinin kullanıcı dostluğunun incelenmesi olduğu durumlarda, bu literatürün spesifik durumlar bazısındaki doğası işin zorluk seviyesinide arttırır. Bu araştırma, kullanıcı dostluğu ve bilgisayar tutumunu, algılanan kullanıcı dostluğunu etkileyen önemli bir değişken olarak önermektedir. İstanbul'daki 26 üniversiteyi kapsayan ana kütleyi temel alan bir saha çalışması ile önerilen model test edilmiştir. Araştırma bulguları; bilgisayar tutumunun algılanan kullanıcı dostluğu üzerinde anlamlı bir etkisi olduğuna işaret etmektedir.IntroductionLiterature ReviewLiterature Review Regarding UsabilityIntroduction to Usability / What is Usability?Different Definitions of the Concept UsabilitySchakel’s Definition of UsabilityNielsen’s Definition of UsabilityISO 9126’s Definition of UsabilityISO 9241’s Definition of UsabilityHow Different Definitions Overlap Each Other?Measuring UsabilityUsability TestingUsability InspectionUsability InquiryQUIS: Questionnaire for User Interface Satisfaction (Chin, 1988)PEUE: Perceived Usefulness and Ease of Use (Davis 1989)NHE: Nielsen’s Heuristic Evaluation (Nielsen, 1993a)NAU: Nielsen’s Attributes of Usability (Nielsen, 1993a)PSSUQ: Post-Study System Usability Questionnaire (Lewis 1992a)CSSUQ: Computer System Usability Questionnaire (Lewis 1992b)ASQ: After Scenario Questionnaire (Lewis 1995)SUMI: Software Usability Measurement Inventory (HFRG)MUMMS: Measurement of Usability of Multimedia Software (HFRG)WAMMI: Website Analysis and Measurement InventoryEUCSI: End User Satisfaction Instrument (Doll, 1994)Literature Review Regarding Computer AttitudeIntroduction to Computer AttitudeVariables that Has Been Studied Regarding Computer AttitudeComputer ExperienceComputer Self-EfficacyComputer AnxietyGenderMeasuring Computer AttitudeLoyd and Gressard (1984) Computer Attitude Measurement ScaleKay (1989) CAM Computer Attitude Measurement ScaleTheoretical FrameworkHypothesis DevelopmentHypothesis of the ResearchResearch DesignResearch ObjectiveResearch Scenario: Shopping in an Ecommerce PortalBasic Research Design IssuesSamplingData Collection MethodResearch ResultsInternal ConsistencyDescriptive StatisticsFrequency DistributionsMeasures of Central Tendencies and DispersionKolmogorov-Smirnoff TestsInferential StatisticsPearson CorrelationHypothesis TestingHypothesis 1Hypothesis 2Hypothesis 3Hypothesis 4Hypothesis 5Hypothesis 6Hypothesis 7Hypothesis 8Hypothesis 9Evaluation of Research ResultsImplications for Further ResearchConclusionDeveloped Questionnair
