Magistrsko delo se osredotoča na dostopnost, inkluzivnost in uporabniško izkušnjo na primeru kooperativnega online bibliografskega sistema in servisov – COBISS-a. Natančneje, na mobilno aplikacijo virtualne knjižnice Slovenija – mCOBISS. Namen raziskave je bil odkriti, kakšni sta uporabniška izkušnja in dostopnost (z nadgradnjo inkluzivnosti) aplikacije ter kje v procesu uporabe najpogostejših funkcionalnosti se v sklopu teh področij pojavljajo težave. Na podlagi pridobljenih rezultatov je bil cilj tovrstne težave prepoznati ter načrtovati in oblikovati nadgrajen uporabniški vmesnik. Na podlagi pristopa k človeku usmerjenega oblikovanja smo izvedli metode raziskovanja, ki vključujejo uporabnike (uporabniško testiranje, intervju in vprašalnik uporabniške izkušnje). Nekatere metode pa smo izvedli samostojno, s pomočjo avtomatiziranih orodij in ročno (testiranje z Accessibility Scanner-jem, hevristično vrednotenje, testiranje z uporabo podpornih tehnologij). Nato smo težave prioritizirali ter izdelali persone. Sledilo je načrtovanje in oblikovanje posodobljenega uporabniškega vmesnika (skice, žični modeli, sistem oblikovanja, prototipiranje) ter ponovno vrednotenje (uporabniško testiranje in vprašalnik uporabniške izkušnje) za primerjavo aplikacij. Rezultati raziskave so pokazali podpovprečne rezultate o splošnem vtisu trenutne aplikacije, največ težav se je pokazalo glede stimulativnosti in originalnosti. Največ težav z uporabniško izkušnjo je bilo glede izbirnega iskanja, najmanj pri preverjanju lokacije knjižnice. Največ težav hevrističnega vrednotenja je bilo s hevristikami št. 5 (preprečevanje napak), 4 (konsistenca in standardi) in 2 (ujemanje sistema z resničnim svetom). Najpogostejše težave glede dostopnosti so bile povezane s cilji dotika. Operacijska sistema Android in iOS omogočata veliko vgrajenih podpornih tehnologij, največ za osebe z vizualnimi okvarami. Večina le-teh pa na aplikaciji mCOBISS deluje le deloma (zgolj za določene elemente ali jezike). Inkluzivnost je področje, ki je še v povojih in trenutno še ni standardiziranih metod raziskovanja za področje uporabniške izkušnje, zato smo pripravili le priporočila za nadgradnjo inkluzivnosti aplikacije. S pomočjo vrednotenja prototipa posodobljene aplikacije smo ugotovili, da smo izboljšali uporabniško izkušnjo aplikacije na vseh področjih. Najvidnejšo izboljšavo smo naredili za parametra atraktivnost in preglednost.

Abstract

The master thesis focuses on accessibility, inclusion and user experience of Co-operative Online Bibliographic System and Services – COBISS. To be more precise, on mobile application of Virtual library of Slovenia – mCOBISS. The aim of our research was to discover the state of user experience and accessibility (with the upgrade to inclusion) within the app and where in the process of using the most common functionalities, in connection to mentioned areas, problems occur. Based on the obtained results, the main goal was to address these issues and plan and design the upgraded user interface. Based on the Human-centered design approach, we performed research methods that included users (usability testing, user interview and user experience questionnaire). While others were carried out independently with the help of automated tools and manual research (testing with Accessibility Scanner, Heuristic evaluation, testing with the use of assistive technology). Next, we prioritized issues and created user personas. This was followed by the planning and designing the updated user interface (sketches, wireframes, design system, prototyping), and re-evaluation (usability testing and user experience questionnaire) for the final application comparison. Research results showed below-average results of the overall impression of the current app, mainly in the areas of stimulation and novelty. Most issues about user experience were connected to selective search and the least to checking library location. The most issues found with Heuristic evaluation were with heuristics no. 5 (error prevention), 4 (consistency and standards) and 2 (match between the system and the real world). The most problematic accessibility issues were about the touch targets. Operating systems Android and iOS offer many built-in assistive technologies, mostly for people with visual disabilities. However, most of these only work partially on the mCOBISS application (only for certain elements or languages). Inclusion is the area that is still developing and there are currently no standardized research methods in the field of user experience. That is why we only prepared recommendation for upgrading the app. By evaluating the prototype of the updated application, we found out that the overall user experience of the application has improved in all areas. The most significant improvement has been visible for parameters attractiveness and perspicuity.
