E-Government Implementation: Transparency, Accessibility and Usability of Government Websites
2017
In several European countries decentralization has promoted the creation of Regional Governments (RGs) with high levels of competence and responsibilities, such as promoting good governance and sustainability. Information and communication technologies (ICTs), and hence, the adoption of e-government has contributed to the adoption and dissemination of government transparency in a usable and accessible way. In this chapter, we study the transparency, accessibility and usability of websites of Spanish RGs.
A methodological framework based on a DANP model for evaluating the software quality in terms of usability: a preliminary investigation on mobile ope…
2020
Evaluation of the software usability as concerns software alternatives represents a typical Multi- Criteria Decision-Analysis (MCDA) problem. Such a kind of problem can be successfully faced via structured models and approaches which validity have been widely shown in literature. In this work, a methodological framework based on a MCDA model integrating the DEMATEL method along with the ANP technique is proposed and explained with more detail to address the relevant issue of the software usability evaluation. The applicability of the considered DEMATEL-ANP (DANP) based model in the under analysis contest is demonstrated via a preliminary investigation, where the usability of the two major M…
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…
Measuring the Effects of Sharing Mobile Health Data During Diabetes Consultations: Protocol for a Mixed Method Study
2020
Background There is rising demand for health care’s limited resources. Mobile health (mHealth) could be a solution, especially for those with chronic illnesses such as diabetes. mHealth can increases patients’ options to self-manage their health, improving their health knowledge, engagement, and capacity to contribute to their own care decisions. However, there are few solutions for sharing and presenting patients’ mHealth data with health care providers (HCPs) in a mutually understandable way, which limits the potential of shared decision making. Objective Through a six-month mixed method feasibility study in Norway, we aim to explore the impacts that a system for sharing patient-gathered…
Emotional obstacles of e-learning

Emotional obstacles for e-learning – a user psychological analysis
2010
E-oppimisen merkitys koulutuksessa on kasvanut jatkuvasti. Sekä julkisen että yksityisen sektorin organisaatiot käyttävät sitä laajasti. Epäilyjä kuitenkin on ilmaistu sen tehokkuuden osalta. Nämä ongelmat johtuvat usein ihmisen ja järjestelmän vuorovaikutuksesta, minkä vuoksi on tarpeen tutkia vuorovaikutusta e-oppimisessa. Me lähestymme näitä vuorovaikutusongelmia käyttäjäpsykologisesta näkökulmasta. Tämä tarkoittaa sitä, että käytämme psykologisia käsitteitä, menetelmiä ja teorioita ratkaistaksemme vuorovaikutusongelmia. Tässä artikkelissa haluamme korostaa, että on olemassa monia tunneperäisiä näkökulmia ihmisen ja teknologian vuorovaikutuksen prosesseille, ja siksi me analysoimme e-opp…
Seeking Technical Debt in Critical Software Development Projects : An Exploratory Field Study
2016
In recent years, the metaphor of technical debt has received considerable attention, especially from the agile community. Still, despite the fact that agile practices are increasingly used in critical domains, to the best of our knowledge, there are no studies investigating the occurrence of technical debt in critical software development projects. The results of an exploratory field study conducted across several projects reveal that a variety of business and environmental factors cause the occurrence of technical debt in critical domains. Using Grounded Theory method, these factors are categorized as ambiguity of requirement, diversity of projects, inadequate knowledge management, and res…
Supporting Agile Development by Facilitating Natural User Interaction with Executable Formal Specifications
2011
Agile development benefits from fast feedback from various stakeholders. If implemented in a suitable way, formal methods can enhance the agile development process. With an executable formal specification, it is possible to analyse and simulate the behaviour of the target system before it is being built. However, for the users' and developers' natural participation in the development process, it is necessary to use a real end-user interface and bind it to the execution environment being used in the simulations and animations. This requires, though, that the execution model used to simulate the specification is appropriately changed to facilitate the use of these user interfaces. The authors…
Affordances and signifiers in virtual learning environment design
2016
Virtuaalioppimisympäristöt edustavat suhteellisen uutta opetusmuotoa. Näiden ympäristöjen suunnittelussa on opetukselle asetettujen vaatimusten huomioimisen lisäksi oleellista ymmärtää yksilön tavat kokea ja ymmärtää käytössä oleva teknologia. Koettu käytettävyys on käsite, joka kuvaa tuote- tai palvelusuunnittelua siltä osin, kuinka ihmiset ymmärtävät käytettävyyttä ja käytön helppoutta. Nämä ymmärrykset on johdettu kohteiden ominaisuuksista ja toiminnoista eli affordansseista, jotka ovat erilaisten vihjeiden eli merkitsijöiden tarjoamia viittauksia siitä, miten kohdetta voidaan käyttää. Tämä tutkielma on toteutettu kirjallisuuskatsauksena. Sen tarkoituksena on määritellä käsitteenä virtua…
