Livsmedelshandel i webbutiker : En tillgänglighetsundersökning med WCAG 2.0 / Grocery shopping in online stores : An accessibility study with WCAG 2.0

Ahlgren, Lucas, Marin Puentes, Angie Melissa January 2018 (has links)
Undersökningen ämnar utreda och utvärdera hur tillgängligheten är i svenska webbutiker för livsmedel. Detta med syftet att upplysa livsmedelsbranschen kring om hur tillgänglighet prioriteras idag, för att på så sätt bidra till att diskussionen kring ämnet blir mer aktiv. Undersökningen innefattade sju svenska livsmedelsbutiker på webben: Ica, Coop, Mat.se, Mathem.se, Willys, Hemköp och City Gross. I varje webbutik utvärderades tillgängligheten på tre webbsidor: startsidan, produktsidan för Arla 1 liter mellanmjölk samt kassan. Utgångspunkten för att utvärdera tillgängligheten på dessa webbsidor var webbstandarden WCAG 2.0, som är den rekommenderade standarden från W3C för att utvärdera tillgänglighet på webben. Undersökningen utfördes med hjälp av utvärderingsverktyg AChecker samt manuella utvärderingar. Resultatet visade att det skiljer mycket mellan olika webbutiker vad gällande tillgängligheten enligt tillgänglighetsstandarden WCAG 2.0. Gemensamt för alla webbutiker var att ingen av dessa uppfyllde den lägsta nivån för WCAG 2.0, nivå A. City Gross bröt mot flest riktlinjer medan Willys bröt mot minst antal riktlinjer i WCAG 2.0. Detta tyder på att tillgängligheten inte prioriteras i dessa webbutiker för livsmedel. / This study aims to evaluate the state of web accessibility in online grocery stores in Sweden. This with the aim of informing the food industry about how accessibility is prioritized today, in order to contribute, to the discussion about this subject becoming more active. The survey included seven Swedish grocery stores on the web: Ica, Coop, Mat.se, Mathem.se, Willys, Hemköp and City Gross. In each web store, accessibility was evaluated on three web pages: the start page, the product page for 1 liter of milk of the brand Arla and the checkout page. The starting point for evaluat-ing accessibility on these web pages was the WCAG 2.0 web standard, which is the recommended standard from the W3C to evaluate accessibility on the web. The study was conducted using an evaluation tool AChecker as well as manual evaluations. The result showed that there is a lot of difference between different web stores regarding accessibility according to WCAG 2.0 acces-sibility standards. Common to all online stores was that none of them met the lowest level of WCAG 2.0, Level A. City Gross broke against the most number of guidelines while Willys broke against the fewest number of guidelines in WCAG 2.0. Which indicates that accessibility is not a priority in these online grocery stores.

Web Accessibility in E-learning : Identifying and Solving Accessibility Issues for WCAG 2.0 Conformance in an E-learning Application

Lundqvist, Sebastian, Ström, Johan January 2018 (has links)
With the rise of e-learning and recent legislations of the European Union enforcing conformance to Web Content Accessibility Guidelines 2.0 for web applications of public sector bodies, the issue of identifying and solving web accessibility issues in e-learning applications is more relevant than ever. This thesis is based on a case study of a publisher of course literature whose intention is to improve the accessibility of their e-learning applications. The thesis contains a theoretical foundation on disabilities, e-learning and web accessibility including assistive technologies, the web accessibility guidelines WCAG 2.0 and the web accessibility evaluation method WCAG-EM. This theory is used for developing solutions to accessibility issues found in the e-learning applications and comparing accessibility with e-learning theory. The results are presented as concrete examples to be useful for developers of e-learning applications. It was found that there exist a few instances where accessibility and e-learning contradict each other, but the solutions to accessibility problems are most often not affected by the learning premise of the applications.

Patient Empowerment and Accessibilityin e-Health Services : Accessibility Evaluation of a Mobile WebSite for Medical Records Online

Johansson, Axel January 2015 (has links)
This thesis evaluates a DEMO version of the mobile web site for medical recordsonline, m.minavardkontakter.se, from a web accessibility point of view. The evaluationis an expert evaluation based on the ISO standard for web accessibility, Web ContentAccessibility Guidelines (WCAG) 2.0 that is complemented with an evaluation basedon fictitious characters, so called personas. The personas were used to representthree groups of people with different kinds of disabilities; perceptual impairment(aniridia), physical impairment (rheumatism) and cognitive impairment (aphasia). Bycombining and comparing these two methods of evaluation, the thesis also evaluatesthe methods themselves. It was seen from both evaluations that the mobile web sitedoes not entirely fulfill the requirements (success criteria) for web accessibility.WCAG 2.0 found more problems in accessibility than did the personas. However, thepersonas found some problems that were overseen by WCAG 2.0, especially whenthe mobile web site was explored using voice synthesis. The results from the twoevaluations were combined in a set of recommendations for improvement, ranked inorder of importance according to the author. The results conclude that WCAG 2.0 isa good tool for evaluating web accessibility but it is recommended to continue to usethe personas in the future development of the mobile web site.

Comparing Web Accessibility between Major Retailers and Novelties for E-Commerce

Xu, Jinmeng January 2020 (has links)
Purpose –Comparing the accessibility of e-commerce for General Merchandise, between major retailers and novelties, in the conformance of web accessibility guidelines, and the implementation of rich internet applications specifications. So that to figure out whether the differences exist between them, if so, what are the differences, and analyzing upcoming e-commerce and established e-commerce.  Method – The descriptive and quantitative case studies were used to evaluated 45 websites respectively from major retailers and novelties in General Merchandise of e-commerce, where sample websites were selected from Alexa’s rank lists. Then the WAVE tool, Accessibility Quantitative Metric (WAQM), and Fona assessment were applied for analyzing cases for representing the accessibilities and answering the research questions of purpose.  Findings – ARIA specifications as a kind of technological solution really had positive functions on web accessibility when only focusing on accessibility guidelines, because the novelty websites with less ARIA attributes resulting in lower accessibility levels generally, even though there were also many other elements that can affect accessibility.  Implications – In the main branch of General Merchandise, the degree of web accessibility in major retailer websites was better than that in novelties, which means as far as e-commerce is concerned, the accessibility of mature websites that had been established for a long time was contemporarily stronger than that of new websites with creative products.  Limitations – From the perspective of the sample, there were limitations in sample sources, size, websites languages, while in the technical aspect, the evaluation of dynamic contents just aims at keyboard navigation, and the tool of Fona assessment also had restrictions.
