An empirical approach for evaluating the usability of model-driven tools
2013
MDD tools are very useful to draw conceptual models and to automate code generation. Even though this would bring many benefits, wide adoption of MDD tools is not yet a reality. Various research activities are being undertaken to find why and to provide the required solutions. However, insufficient research has been done on a key factor for the acceptance of MDD tools: usability. With the help of end-users, this paper presents a framework to evaluate the usability of MDD tools. The framework will be used as a basis for a family of experiments to get clear insights into the barriers to usability that prevent MDD tools from being widely adopted in industry. To illustrate the applicability of …
Usability Challenges in Surgical Simulator Training
2009
Surgical virtual reality simulators have been taken into use in order to improve surgical skills training. Emergence of simulators increases the need for research and knowledge related to usability of medical simulators. In this study usability of laparoscopic surgical simulator was researched experimentally through combined analysis. Data was gathered with heuristic evaluation, questionnaires, and interviews as well as recorded simulator parameters. Results suggest that the surgical simulator could be more efficient learning and training tool if usability issues such as support and error prevention were reconsidered in more detail. There also seem to be grounds for connecting user support …
The EU-project United4Health: User-centred design of an information system for a Norwegian telemedicine service.
2015
Introduction Organizational changes of health care services in Norway brought to light a need for new clinical pathways. This study presents the design and evaluation of an information system for a new telemedicine service for chronic obstructive pulmonary disease patients after hospital discharge. Methods A user-centred design approach was employed composed of a workshop with end-users, two user tests and a field trial. For data collection, qualitative methods such as observations, semi-structured interviews and a questionnaire were used. Results User workshop’s outcome informed the implementation of the system initial prototype, evaluated by end-users in a usability laboratory. Several us…
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…
Applying Minimalism in the Real World: Results From a Workshop
2020
Minimalism is a user-centered, contextual and goal-oriented approach to technical communication originally developed by John M. Carroll (1990). In minimalism, the aim is to produce user documentation that focuses on the user’s needs, helps the user recover from error situations, and strengthens the user’s skills in working with the system (Carroll & van der Meij 1995: 245). The challenge with minimalism has been its practical application: although user-centeredness – the core of minimalism – is the key issue in technical communication, the abstract nature of the approach and its focus on software documentation has made it difficult to apply in industry settings (Virtaluoto, Suojanen & Isohe…
Vastuullisuusarvot suomalaisten tekstiiliyritysten tarinoissa
2022
Textile industry causes significant negative environmental and social impacts. Sustainability in the industry has lately yielded more and more research interest, however, sustainability communication is underresearched area. In this paper, we will focus on sustainability communications in the Finnish textile industry through the stories of companies in their webpages. Storytelling has traditionally been a mode of transmitting, producing and reproducing the culture. Stories produce a structure in the reality, explain phenomena and concretize abstract concepts. In this research, we approach the stories as rhetorical devises, which address, attract and connect the reader to the company behind …
Validation and Extension of the Usability Heuristics for Mobile Map Applications
2016
Heuristic usability evaluation is light but efficient method for finding usability problems. In this paper, we report the process of validation and further development of the previously introduced usability heuristics for mobile map applications. The validation began by testing the heuristics by 58 evaluators who used them for usability evaluation of four different map applications. The evaluators also filled a questionnaire about the understandability of the heuristics. The amount, severity and quality of the problems found with the heuristics were reviewed and the heuristics’ understandability analyzed. As a result, it was shown that the heuristics were efficient for finding usability pro…
Design time, run time, and artificial intelligence techniques for mobility of user interface
2011
Abstract Advancement in technology provides opportunities to user as well as challenges for application development organization. User interfaces which were design for specific device tend to be developed for various devices. Users are busy people, when they move among different context would like to move application with them. The current trend of users demanding mobile graphic user interface to support their daily life and work has led to a new generation of techniques. Design time technique provides better usability as compare to run time technique. On the other hand artificial intelligence technique like agent provides better flexibility and usability as compare to others. In this paper…
