Explaining Accessibility: Possible Variables in Users’ Abilities, Tasks, and Contexts in IT Artefact Use

The interconnection between the two information technology (IT) artefact qualities, accessibility and usability, is challenging to define. Efforts to design and develop accessible IT artefacts should encompass the broadest range of user abilities in identified tasks and contexts. We lack sufficient research on information systems and human-computer interactions that presents a comprehensive model to explain what variables these key components of accessibility contain and how they interconnect. To address this gap in the literature, I draw on theories beyond human-computer interactions, tasks, and contexts to posit the influence of human abilities on IT use by referring to the International Classification of Functioning, Disability, and Health (ICF) framework that the World Health Organization developed. In this paper, I theoretically describe accessibility, its components, and their relationships in the IT use context based on which I present an accessibility model. Furthermore, I argue that accessibility is a moderating variable between system features and usability. Therefore, accessibility is a major determinant of user acceptance

Towards Design Theory for Accessible IT Artefacts

Accessibility in the use of information technology (IT) artefacts, such as websites, applications, and user interfaces, means that they are designed in such a way that people with the broadest range of abilities can use them. However, although accessibility is a human right, IT artefacts often remain inaccessible. Aside from the available accessibility guidelines, we need sufficient design theories that explicitly state how accessibility should be addressed and designed to develop accessible IT artefacts for all users. This dissertation summarises four articles that address this problem. These studies are conducted with qualitative approaches that include a narrative literature review, a systematic literature review and a design science method comprising a participatory design and interviews. The first article develops an explaining theory of accessibility to gain an understanding of the construct of accessibility, showing possible variables of human abilities, tasks and contexts and their relationships in IT use. The second article illustrates the factors in management, development, user, and IT artefact features, including the roles and actions that these domains have and how they affect the realisation of accessibility. The other two articles contribute to accessibility guidance to improve and support content creators’ text production and writing process of accessible online text in the web context. The dissertation underscores three key determinants of the knowledge of accessibility: (1) assumptions of users’ abilities; (2) users’ actual needs; and (3) factors in the development chain. The foregoing factors contribute to the knowledge of accessibility and would help researchers, particularly design scientists, form prescriptive knowledge for practitioners to achieve accessible IT artefacts. Thus, researchers could better identify the variables, relationships and affecting factors in human abilities, management, development, content creation, tasks, and contexts that need to be addressed when designing IT artefacts for certain tasks and use contexts.Informaatioteknologia-artefaktien (IT-artefaktien), kuten verkkosivustojen, sovellusten ja käyttöliittymien saavutettavuus tarkoittaa sitä, että ihmiset erilaisine ominaisuuksineen ja kykyineen voivat käyttää niitä. Vaikka saavutettavuus on ihmisoikeus, IT-artefaktit eivät kuitenkaan ole aina saavutettavia. Käytettävissä olevista saavutettavuusohjeista huolimatta tarvitsemme suunnitteluteorioita, jotka ohjaavat IT-artefaktien suunnittelua, jotta niistä tulisi saavutettavia kaikille IT-artefaktin käyttäjille. Tämä väitöskirja on yhteenveto neljästä artikkelista, jotka käsittelevät tätä ongelmaa. Tutkimukset ovat tehty laadullisilla menetelmillä, joihin on sisältynyt narratiivinen kirjallisuuskatsaus, systemaattinen kirjallisuuskatsaus sekä suunnittelutieteellinen menetelmä sisältäen osallistavan suunnittelun ja haastattelut. Ensimmäisessä artikkelissa kehitetään kuvaileva saavutettavuuden teoria, jolla saadaan käsitys saavutettavuuden rakenteesta ja joka näyttää mahdolliset muuttujat ihmisen kyvyissä, tehtävissä ja konteksteissa, sekä niiden väliset suhteet. Toinen artikkeli kuvaa saavutettavuuteen vaikuttavia tekijöitä johtamisen, kehityksen, käyttäjän ja IT-artefaktin ominaisuuksien näkökulmista, mukaan lukien roolit ja toimenpiteet, joita näillä kohteilla on. Kaksi muuta artikkelia kehittävät ohjeistuksen sisällöntuottajien työn tueksi saavutettavan verkkotekstin tuottamiseksi. Väitöskirjassa esitetään kolme ratkaisevaa tekijää saavutettavuuden tietämyksessä: (1) olettamukset käyttäjien kyvyistä (2) käyttäjien todelliset tarpeet ja (3) tekijät kehitysketjussa. Näiden tekijöiden tuntemus auttaa erityisesti suunnittelutieteilijöitä muodostamaan ohjaavaa tietoa ammattilaisille saavutettavien IT-artefaktien saavuttamiseksi. Täten tutkijat voivat paremmin tunnistaa muuttujat, niiden väliset suhteet ja saavutettavuuteen vaikuttavat tekijät, jotka liittyvät käyttäjän kykyihin, johtamiseen, kehittämiseen, sisällöntuottamiseen, tehtäviin ja kontekstiin, kun IT-artefaktia suunnitellaan tiettyä tehtävää ja käyttökontekstia varten.fi=vertaisarvioitu|en=peerReviewed

UNDERSTANDING MOTIVATORS AND CHALLENGES IN ACCESSIBILITY DEVELOPMENT

We analyzed secondary data from nine studies including a total of 1962 respondents on what motivates web practitioners such as user experience developers, web designers, and web masters’ intention to promote accessibility, and what challenges they encounter during accessibility development. In this ex-ploratory study, we adopt the viewpoint of motivation and challenges and aim to study them from in-trinsic and extrinsic viewpoints. We then interpreted intrinsic and extrinsic motivators and intrinsic and extrinsic challenges that should be addressed in the management of accessibility work so that the main accessibility milestones become implemented in the design of information technology artifacts. We re-trieved recommendations for top management and superiors to gain and support practitioners’ motiva-tion and to address challenges in accessibility development to avoid ethical conflict in accessibility development. These findings strengthen an understanding of possible ethical conflicts in accessibility development and help to act responsibly in the accessibility development of information systems

How to Incorporate Accessibility to Design Principles for IS Artefacts?

Design principles are used to specify design knowledge and describe the aim of artefact instantiation. Accessibility research aims to create artefacts that can be used by all users. However, schemes for design principles lack the tools to define accessibility explicitly. This study proposes extensions to scheme design principles for accessibility-related design science research. We draw accessibility domain-specific characteristics from the literature to include accessibility in design principles for Human-Computer Interaction (HCI) instantiations. We extended the components of design principles with the following attributes: HCI Artefact Features; Contextual factors; Computer Input Modalities; Computer Output Media; Human Sensory Perception; Human Cognition; Human Functional Operations. We devised a checklist for researchers to follow the variations in accessibility. The extensions are intended to foster researchers to incorporate accessibility in producing a more accurate formulation of design principles.© authors, Welzer Družovec, Hölbl, Nemec Zlatolas, Kuhar, 2023.

Designing Heuristics for Accessible Online Text Production

Governments and public organisations provide digital services and share information on websites, so web content needs to be accessible to all citizens. Text remains the main form of providing information, and reading is the primary way to interact with digital services. However, existing guidelines are not adequate for content creators in public organisations. The wide scope and technicality of these guidelines make them confusing, difficult to understand and challenging to implement. To respond to this emerging need, in this paper, we contribute improvements to the guidance of accessible text production by proposing heuristics with a design science approach. Specifically, we (1) review accessibility guidelines and determine improvement factors related to text accessibility, (2) establish a design and evaluation workshop with 38 students, and (3) verify the feasibility of the proposal with content creators. Our evidence shows that the proposed accessibility heuristics are clear and easy to understand, and they are useful for content creators.© 2022 Scandinavian Journal of Information Systems & Authors.fi=vertaisarvioitu|en=peerReviewed

Verkkopalvelun tuottaminen japanilaisille vaihto- ja tutkinto-opiskelijoille

Opinnäytetyön aiheena on suunnitella verkkopalvelu japanilaisille vaihto- ja tutkinto-opiskelijoille. Verkkopalvelu käsittää portaalin, josta löytyvät kaikki vaihto-opiskeluun liittyvät asiat. Portaalin tavoitteena on tarjota opiskelijoille tietoa vaihtoon lähdöstä Suomeen, sekä opiskelusta ja asumisesta Suomessa. Erityisenä painopisteenä työssä on käyttäjien tarpeisiin perustuvan verkkopalvelun suunnittelu. Opinnäytetyössä yhdistyvät kirjallisuudesta saatu teoria ja käytännön toteutus. Työn tavoitteena on käydä läpi verkkopalvelun tuottamisen vaiheet täsmällisesti esitutkimuk-sesta suunnitteluun. Työssä suunnitellaan japanilaisille vaihto- ja tutkinto-opiskelijoille suunnattu portaali, jolle annetaan myös sisällön ja linkkien ehdotukset. Tavoitteena on siis suunnitella toteutusta vaille oleva vaihto-opiskelija portaali. Työn empiirisessä osiossa tehtiin opiskelijoiden tiedontarpeita ja Internetin käytön tot-tumuksia kartoittava käyttäjäselvitys. Selvitys toteutettiin web-pohjaisella kyselylomak-keella, jonka linkki välitettiin osapuolille. Selvitykseen osallistui yhteensä kahdeksan japanilaista vaihto- ja tutkinto-opiskelijaa. Selvityksen tavoitteena oli etsiä opiskelijoita kiinnostavia Suomea koskevia aiheita, joita voitaisiin tarjota portaalissa. Tavoitteena oli myös määritellä portaalin käyttäjäryhmä ja sen ominaisuudet. Käyttäjäselvityksen tavoite toteutui hyvin kerätyllä aineistolla ja tulokset antoivat paljon aiheita portaalin jatkokehitykseen. Tulokset myös täsmensivät portaalin suunnitellussa tehtyjä määritelmiä ja ehdotuksia. Työn lopputuloksena on yksityiskohtainen verkkopalvelun suunnittelun vaiheet läpi-käyvä kokonaisuus, jonka määritelmillä voidaan siirtyä varsinaiseen portaalin toteutuk-seen ja testaukseen. Jatkokehitykselle ja toteutuksen onnistumiselle portaali tarvitsee ylläpidon toimintaa tukevan organisaation tuekseen.fi=Opinnäytetyö kokotekstinä PDF-muodossa.|en=Thesis fulltext in PDF format.|sv=Lärdomsprov tillgängligt som fulltext i PDF-format

Factors Affecting the Accessibility of IT Artifacts: A Systematic Review

Accessibility awareness and development have improved in the past two decades, but many users still encounter accessibility barriers when using information technology (IT) artifacts (e.g., user interfaces and websites). Current research in information systems and human-computer interaction disciplines explores methods, techniques, and factors affecting the accessibility of IT artifacts for a particular population and provides solutions to address these barriers. However, design realized in one solution should be used to provide accessibility to the widest range of users, which requires an integration of solutions. To identify the factors that cause accessibility barriers and the solutions for users with different needs, a systematic literature review was conducted. This paper contributes to the existing body of knowledge by revealing (1) management- and development-level factors, and (2) user perspective factors affecting accessibility that address different accessibility barriers to different groups of population (based on the International Classification of Functioning by the World Health Organization). Based on these findings, we synthesize and illustrate the factors and solutions that need to be addressed when creating an accessible IT artifact

Citizen science in information systems research: Evidence from a systematic literature review

Citizen science refers to partnerships between scientists and the public in scientific research. Citizen science is considered as an emerging approach for conducting research in the field of information systems (IS). However, there is a fragmented understanding of citizen science in the IS community. As a result, we conducted a systematic literature review on citizen science in IS field aiming at understanding what and how IS scholars view and conduct their research related to citizen science. We searched papers from the database of the basket of eight senior journals, 47 SIG recommended journals by the Association for Information Systems, and the proceedings of five major conferences in IS including ICIS, ECIS, HICSS, PACIS, and AMCIS. Our findings provide the current status of citizen science research in IS field, such as how scholars view about citizen science, how to set up a citizen science project, or how citizen science is adopted in IS community. This research also contributes to the field by laying out suggestions for the future research of citizen science

Exploration of Ideas for Sustaining Digital Innovation Management : A Case Study in the Ostrobothnia Region of Finland

Disruption of technologies, climate changes and epidemic crises have significantly affected individuals, organizations, and society. These phenomena force organizations to extend and innovate their business models to adapt to new circumstances. However, literature provides a limited coverage on how sustainable innovations ideas form and evaluate in practice. We thus focus on this issue in the present study. We used nominal focus group technique, C-K design theory for innovative design with citizen sciences as our study’s lenses. Data collection was from three groups of 81 participants who live in three cities in the Ostrobothnia region of Finland. The findings illustrate the process of establishing a sustainable innovation management idea and lesson learned on how to facilitate innovation groups in practice.©2022 Association for Information Systems.fi=vertaisarvioitu|en=peerReviewed
