Web accessibility means that disabled people can effectively perceive, understand, navigate, and interact with the web. Web accessibility evaluation methods are needed to validate the accessibility of web pages. However, the role of subjectivity and of expertise in such methods is unknown and has not previously been studied. This article investigates the effect of expertise in web accessibility evaluation methods by conducting a Barrier Walkthrough (BW) study with 19 expert and 57 nonexpert judges. The BW method is an evaluation method that can be used to manually assess the accessibility of web pages for different user groups such as motor impaired, low vision, blind, and mobile users.

The role of visual features in text-based captchas: an fnirs study for usable security Mülazimoğlu, Emr; Acartürk, Cengiz; Department of Cyber Security (2019) In order to mitigate dictionary attacks or similar undesirable automated attacks to information systems, developers mostly prefer using CAPTCHA challenges as Human Interactive Proofs (HIPs) to distinguish between human users and scripts. An appropriate use of CAPTCHA requires a setup balance between robustness and usability during the design of a challenge. The previous research reveals that most of the usability studies have used accuracy and response time as measurement criteria for quantitative analysis....
The role of attention for visual perception in desktop virtual reality environments Karacan, Hacer; Çağıltay, Kürşat (null; 2009-08-09) Virtual Reality Environments (VRE) is relatively new types of human-computer interaction interfaces in which users perceive and act in a 3D world. Researchers use it both as a tool and as an experimental area for their studies. In this study, a desktop VRE was created and used to explore the role of attention for visual perception of 60 university students who participated to the study. The findings showed that configurational knowledge can be attained in desktop VRE. Furthermore, it is found that visual at...
The Investigation of interface usage on tablets for reading comprehension: a mixed method study Aytekin, Özge; Yıldırım, İbrahim Soner; Toker, Sacip; Department of Computer Education and Instructional Technology (2019) The aim of this study is to investigate the effect of website design on interface usage interactions on tablets and the connection between interface usage interactions on tablets with reading comprehension. For this purpose, mixed method study was performed. Responsive and non-responsive website designs were used for the first of the study. In total, 58 students participated in the experiment where students read texts on tablets. The application took about 15 minutes. Responsive and non-responsive website d...
Application of Wiener Deconvolution Model in P300 Spelling Paradigm Erdogan, Balkar; Gençer, Nevzat Güneri (2009-01-01) Spelling Paradigm first introduced by Farwell and Donchin, is one of the Brain Computer Interface (BCI) applications that enables paralyzed people to communicate with their environment. In such a problem, user needs to focus on the characters which are randomly flashed row or column-wise on the computer screen in a small period of time. The accuracy in spelling words is the main problem in this scheme and the duration of the correct prediction is quite important. The purpose of this work is twofold: to anal...
The dimensions of users' fun experiences with consumer products Cila, Nazlı; Erbuğ, Çiğdem; Department of Industrial Design (2008) User experience (UX) is a multi-dimensional user-product interaction involving positive and emotional usage. Fun experience is a component of UX which maintains distinctive dimensions. In this study these dimensions of the fun concept, namely the nature of the experience, the qualities of products that take place in the experience, and the emotional content of the fun experiences are investigated. The thesis is supported by arguments collected from the literature and the data from two empirical studies.
