Training and Deployment as a Basis for Usability Engineering of Mobile Systems
2008
Usability engineering of mobile systems challenges existing methods and raises new concerns. Usability evaluations are frequently described as a separate discipline and in many cases usability evaluations are separate activities within the design and development of systems. This paper presents a development project where training in and the deployment of a mobile system were used to identify usability problems. The project aimed to develop a mobile system to supporting information processes for workers on building sites. An iterative usability evaluation process was conducted the process was refined and validated using two action research projects. The approach of the research was user-cent…
Usability remote evaluation: METBA system
2012
Usability as well as accessibility is a key aspect in development of human-computer interaction. This paper presents the basis of usability evaluation methodology and reviews the methodology used in empirical studies of usability evaluation for disabled people. Finally, we present a solution (METBA) as a system for managing the information related to evaluation of human behavioral observation contents that is used for the registration and management of the information derived from remote usability evaluation which complements the methodology commonly used in this research area.
Filtering usability data with reference to behavior
2011
No company can stay in business without having a "useful" web presence. The question is how usefullnes can be achieved. Usefullnes in this sense is how attractive and useful it is for the visitors. This can be done by observing the visitors' behavior. Doing this through interviews and observation of users in their living rooms is expensive and in many cases even impractical. So, other means need to be found. This paper presents a tool for the evaluation of usefulness of a web presence by extracting and analyzing information out of its log files. The information extraction can be refined using a set of filters which can be arbitrarily combined by the usability engineer responsible for mainta…
A Quantitative Method for Localizing User Interface Problems: The D-TEO Method
2009
A large array of evaluation methods have been propo sed to identify Website usability problems. In log-based evaluation, inform ation about the performance of users is collected and stored into log files, and used to find problems and deficiencies in Web page designs. Most methods require the programming and modeling of large task models, which are cumbersome processes for evaluato rs. Also, because much statistical data is collected onto log files, recognizing which Web pages require deeper usability analysis is difficult. This paper suggests a novel quantitative method, called the D-TEO, for locating problematic Web pages. This semiautoma ted method explores the decomposition of interacti…
Towards the Learning Experience Technology Usability framework
2017
The availability of learning technology has increased over past decades; however, severe usability issues that cause adverse effects on the learning experience can be found in many available technologies. Learning solution usability is commonly evaluated by focusing on either technical or pedagogical usability and rarely both. This artificially separates the two important aspects of learning technology usability. This chapter provides a new framework for designing and evaluating learning solutions that synthesizes the above usability types to consider them a part of a complex and dynamic whole comprising of learning, technological design, content-related issues and context. The proposed Lea…
