Factors explaining adoption and implementation processes for web accessibility standards within eGovernment systems and organizations 2017, Article / Letter to editor (Universal Access in the Information Society, vol. 16, (2017), pp. 173-190)Local government organizations such as municipalities often seem unable to fully adopt or implement web accessibility standards even if they are actively pursuing it. Based on existing adoption models, this study identifies factors in five categories that influence the adoption and implementation of accessibility standards for local government websites. Awareness of these factors is importap and understand these factors, this study has identified and interviewed experts in the field of (organizational) accessibility. This has led to an extension of the existing models. The extended model was then validated by interviews with key stakeholders. The outcome of this study places existing adoption models in a new context. The result is an adoption model that contributes better to explaining adoption and implementation processes within eGovernment systems and organizations. This adoption model aims to better help local governments in the identification of factors influencing the actual adoption and implementation of web accessibility standards in their situation. The model explains how factors in the different categories contribute to the adoption and implementation of web accessibility standards. The model may also be applicable to the adoption and implementation of other guidelines and (open) standards within local government. -
Developing Accessibility Design Guidelines for Wearables: Accessibility Standards for Multimodal Wearable Devices. 2016, Article / Letter to editor (Lecture Notes in Computer Science, vol. 9737, (2016), pp. 109-119)Smart wearable devices are integrated our everyday lives. Such wearable technology is worn on or near the body, while leaving both hands free. This enables users to receive and send information in a non-obtrusive way. Because of the ability to continuously assist and support activities, wearables could be of great value to persons with a disability. Persons with a disability can only benefit from the potential of wearables if they are accessible. Like other devices, platforms, and applications, developers of wearables need to take accessibility into account during early development, for example by including multimodal interfaces in the design. Even though some accessibility guidelines and standards exist for websites and mobile phones, more support for the development of accessible wearables is needed. The aim of our project is to develop a set of guidelines for accessible wearables. Three approaches are combined to develop the guidelines. A scan of the literature was done to identify publications addressing the accessibility of wearables and/or development guidelines. Semi-structured interviews were held with developers of accessible wearable technology. Based on these first activities, a draft set of guidelines is created. This draft is evaluated with developers and researchers in the field of universal design, accessibility, and wearables. Further, the draft is evaluated with visually impaired people (VIP) in interviews. Based on these results, a final set of guidelines will be created. This set is evaluated against an actual project in which apps are developed for VIP. This study is in progress; first results are presented (literature study, semi-structured interviews, first draft of guidelines) and a call for participation in the Delphi study is issued

Wearables for all: development of guidelines to stimulate accessible wearable technology design 2016, Article / Letter to editor (ACM International Conference Proceeding Series, (2016), pp. 1-4)In this paper, we present the rationale and approach for establishing guidelines for the development of accessible wearables. Wearable technology is increasingly integrated in our everyday lives. Therefore, ensuring accessibility is pivotal to prevent a digital divide between persons who have and persons who lack access to these devices, caused by their abilities. We present a project in which guidelines are created that enable developers to design accessible wearable apps and technologies. These guidelines will be created with developers who have experience with designing accessible technology and/or wearables. In addition, users who (potentially) experience problems with accessibility of wearables (persons who have a disability) are involved in the development of the guideline, to ensure their validity from an end-user perspective.
