Aim of the study was to discuss and identify individual differences that influence the user performance during usability tests of consumer products that are known to prevent researchers to conduct systematic studies. The rationale behind the study was developing a tool for sampling in order to handle experiential factors as a variable rather than a source of error. The study made it possible to define and elaborate on constructs general interaction expertise (GIE) and general interaction self efficacy (GISE), and to devise a measurement scheme based on performance observation and attitude measurement. Both perspectives were evaluated with preliminary validity studies and it was possible to provide evidence on predictive validity of the tool developed. Furthermore, opportunities of utilizing the results in design and qualitative research settings were also explored.

A Lexicon for product experience related communication
Onuşluel, Gonca; Özcan Vieira, Elif; Pedgley, Owaın Francıs; Department of Industrial Design (2012)
In this thesis, product experiences were analyzed in human-product interaction context. The terminology to describe product experiences were gathered and grouped with the studies carried out during the thesis. The conceptual network of product experiences were attempted to be established by examining the stages of human-product interaction in the limitations of the studies. The gathered terminology was composed of both concrete and abstract product features. The abstract product features which are used for ...
A comparison of data mining methods for prediction and classification types of quality problems
Anaklı, Zeynep; Anaklı, Zeynep; Department of Industrial Engineering (2009)
In this study, an Analytic Network Process (ANP) and Preference Ranking Organization MeTHod for Enrichment Evaluations (PROMETHEE) based approach is developed and used to compare overall performance of some commonly used classification and prediction data mining methods on quality improvement data, according to several decision criteria. Classification and prediction data mining (DM) methods are frequently used in many areas including quality improvement. Previous studies on comparison of performance of the...
A comparison of orthogonal cutting data from experiments with three different finite element models
Bil, H; Kilic, SE; Tekkaya, AE (Elsevier BV, 2004-07-01)
The aim of this study is to compare various simulation models of orthogonal cutting process with each other as well as with the results of various experiments. Commercial implicit finite element codes MSC.Marc, Deform2D and the explicit code Thirdwave AdvantEdge have been used. In simulations, a rigid tool is advanced incrementally into the deformable workpiece which is remeshed whenever needed. In simulations with MSC.Marc and Thirdwave AdvantEdge, there is no separation criterion defined since chip format...
Investigation into adaptive structure in software-embedded products from cybernetic perspective
Yurdakul, E. Ertuğrul; Şener Pedgley, Bahar; Department of Industrial Design (2007)
This study investigates the concept of adaptivity in relation to the evolution of software and hence software embedded products. Whilst laying out the benefits of adaptivity in products, it discusses the potential future threats engendered by the actual change observed in the functionality principles of adaptive products. The discussion is based upon cybernetic theory which defines control technology in the 20th century anew. Accordingly, literature survey on cybernetic theory, evolution of software from co...
An evaluation of the reinsepction decision policies for software code inspections
Nalbant, Serkan; Köksal, Gülser; Department of Industrial Engineering (2005)
This study evaluates a number of software reinspection decision policies for software code inspections with the aim of revealing their effects regarding cost, schedule and quality related objectives of a software project. Software inspection is an effective defect removal technique for software projects. After the initial inspection, a reinspection may be performed for decreasing the number of remaining defects further. Although, various reinspection decision methods are proposed in the literature, no study...
