The aim of this study is to analyze and comparatively evaluate the usability of touch screen mobile applications through cognitive modeling and end-user usability testing methodologies. The study investigates the accuracy of the estimated results of a cognitive model produced for touch screen mobile phone interfaces. A mobile wallet application was chosen as the mobile software. The CogTool modeling tool was used as the cognitive modeling method. Eight tasks were determined and user tests were conducted in a usability laboratory with 10 participants. The tasks were compared on the basis of step time and total task completion time. This study reveals that CogTool gives approximate estimations with actual user performance on touch screen mobile phone application interfaces. However, if there are special cases in the tasks such that users are very accustomed to the steps or decision-making that is involved in the tasks, the Think Operation in CogTool should be modified.

Comparison of cognitive modeling and user performance analysis for touch screen mobile interface design Ocak, Nihan; Çağıltay, Kürşat; Department of Information Systems (2014) The main aim of this thesis is to analyze and comparatively evaluate the usability of touch screen mobile applications through cognitive modeling and end-user usability testing. The study investigates the accuracy of the estimated results cognitive model produces for touch screen mobile phone interfaces. CogTool application was used as the cognitive modeling method. Turkcell Cüzdan application, which is suitable for the implementation of both methods, was chosen as the mobile application. Based on the feedb...
A Study on quality assessment on mobile B2C applications Yıldız, Ekrem; Bilgen, Semih; Department of Information Systems (2014) This study aims to provide mechanisms to analyze the quality of the Business to Customer (B2C) mobile software products based on mobile-specific characteristics and quality factors, and sub-factors based on ISO 25010 product quality model which would help mobile software developers, designers and testers to develop more effective mobile applications. We aim to help development of more qualified and effective mobile applications from not only developers’ perspective but also endusers’ perspective. For this p...
Organizational adoption of mobile communication technologies Arpacı, İbrahim; Demirörs, Onur; Department of Information Systems (2013) The purpose of this study is to identify the key adoption factors for mobile communication technologies, specifically smartphones, at private sector organizations. We have proposed a comprehensive research model based on the Diffusion of Innovation theory, Institutional theory, and Technology-Organization-Environment framework. Sequential explanatory design mixed method research strategy, which incorporates quantitative and qualitative approaches was used in this research. A Structural Equation Model was us...
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...
Use of large multi touch interfaces: a research on usability and design aspects Dönmez, Mehmet; Çağıltay, Kürşat; Department of Information Systems (2015) This study explores the design considerations and usability factors of using large multi touch interfaces. During this study, an experimental approach incorporating a large multi touch interfaces environment was used. After the expert analysis and pilot test session, there were end user usability test sessions. During the data collection from both expert and non-expert users, there were interview sessions. After collecting data, two different analysis methods were used, namely, analysis for eye movement dat...
