Developer Driven and User Driven Usability Evaluations
2020Co-Authors: Anders BruunAbstract:Software companies focusing on Usability Engineering face two major challenges, the first being the sheer lack of Usability Specialists leading to missing competences in the industry and the second, which regards small companies suffering from the constraint of low budgets, thus not being able to fund Usability Specialists or comprehensive consultancy. Training of non-Usability personnel in critical Usability engineering methods has the potential of easing these challenges. It is, however, unknown how much and what kind of research that has been committed to novice training in UE methods. This paper presents a comprehensive literature study of research conducted in this area, where 129 papers are analyzed in terms of research focus, empirical basis, types of training participants and training costs. Findings show a need for further empirical research regarding long term effects of training, training costs and training in user based evaluation methods. Author Keywords Training, developers, Usability engineering, literature review. ACM Classification Keywords H5.2 Information interfaces and presentation (e.g.,HCI): User Interfaces -User-centered design, Training, help and documentation. INTRODUCTION During the last decade large software companies have increased their focus on introducing Usability engineering (UE) methods into the development processes. One challenge for these companies is the sheer lack of Usability Specialists in the industry, which leads to missing competences across the board and hence, problems with incorporating UE in the development processes [16, 24]. However, small companies do not even have the privilege of staffing Usability Specialists and these have to cope with issues such as the constraint of low budgets. In practice this means that small software companies do not have the funds to pay for comprehensive consultancy or staffing of Usability Specialists [13, 18, 28] as they are expensive to hire [23]. A survey conducted by Gulliksen et al. acknowledges this by showing that Usability Specialists are primarily employed by medium-sized or large companies [12]. In their study 70 % of the 194 respondents, are employed Usability Specialists in companies with at least 50 employees, which are categorized as medium-sized [9]. This is also supported by Rosenbaum et al. that shows that most Usability Specialists are employed in large companies consisting of 250 or more employees [25]. The fact that small companies usually do not have staff with Usability competences is expressed as one of the main barriers for incorporating UE in the development process [22]. This is also supported in the survey presented in [25] that shows that 17.3 % of 134 respondents mentioned missing competences as one of the main obstacles. One way of solving the problems of incorporating UE in software companies is to increase knowledge of the subject across the set of stakeholders [12]. Thus, training non- Usability personnel in critical Usability engineering methods has the potential of easing problems regarding the lack of Usability Specialists in the industry, which is experienced in large companies. Training also provides an opportunity for small companies to apply UE methods as the developers themselves are driving the UE process, thus lessening the need to staff Usability Specialists, which cannot be funded. Some studies provide promising insights regarding training of Usability novices in UE methods. Metzker and Offergeld describe a software project in which developers participated in contextual task analysis, which motivated the participants to produce components with a high level of Usability [22]. Another study presented in [17] describes how a non- Usability Specialist learned to apply a Usability evaluation method. The participant stated that only little experience with cognitive psychology was needed in order to apply the method. Seffah et al. describes the opposite case in which Usability Specialists having sufficient technical knowhow eased integration of UE methods in the development process and gained wide acceptance from developers [29].

Usablity in Government Systems User Experience Design for Citizens and Public Servants, 2012Co-Authors: Elizabeth Buie, Dianne MurrayAbstract:As a Usability Specialist or interaction designer working with the government or technical government employee you are faced with dealing with a variety of different interfaces and systems on a daily basis then this book is for you. Editors Elizabeth Buie and Dianne Murray have brought together over 30 experts to outline practical advice to both Usability Specialists and government technology professionals. Working with internal and external government systems is a unique and difficult tasks due to the large government secured data-heavy systems and the problem of creating open web portals that isolate information to share with the public while keeping policy and confidential information secure. Open government, design of voting systems, biometrics, ethics, internal vs. external systems and cross-cultural issues as well as working with the government are all covered in this book. Covers both public-facing systems and internal systems run by governments Details Usability tactics specific to government websites, intranets, and applications The practicality of the material presented allows you to take the information and immediately use it to make a difference in their projects. ?? 2012 Elsevier Inc.

Introduction in the web-ergonomics
2020Co-Authors: I. A. MusinaAbstract:This paper is designed as an introduction to a several papers that focus on relatively new field in applied psychology – Usability. In this paper we discussed goals and tasks of user interface designer who is developing useful, needed, effective and psychologically attractive web-products in Internet. Also we are talking about stages of developing web-products and steps in professional activity of Usability Specialist. Also we present general brief review of the methods and techniques that may be utilized in user interface design by Usability Specialists. More detailed information about methods in Usability will be presented in the next papers.

Web LogVisualizer for Communication and Information Management
2016Co-Authors: José Nunes, Florin Zamfir, Óscar Mealha, Beatriz Sousa SantosAbstract:This paper describes an application intended to help a Usability Specialist to analyze a web site. Details like the site map, page information distribution and hotspot location on the pages, for the general site view, but also information like site statistics and user session selection and analysis are offered to the user. In the single session analysis, if more information (like mouse or eye tracking information) is available, it can be added to the information extracted from a LOG file and used appropriately.
