Improving access to information and technology for visually impaired people is a significant challenge within the field of Human-Computer Interaction. In the last decades assistive technology has helped to increase the autonomy and quality of life of the 285 million visually impaired people worldwide. Interactive technologies can support visually impaired people in many tasks, such as navigation and wayfinding, reading and writing, access to education, or even gaming (Brock et al. 2015, Scheibler 2014). It also helps disabled people to stay in touch with friends and participate in social networks and communities (van der Geest et al. 2014). Although legal regulations on accessibility (e.g. BGG 2003) and detailed W3C-guidelines (2009) exist since many years, the majority of websites, location based services, e-learning applications and games are still not designed and programmed to be accessible, even with assistive technology (vgl. AbleGamers Foundation 2012, Köhlmann 2014, Michalska et al. 2014, Wentz & Lazar 2011). In addition, the specific needs of people with different forms of visual impairment and blindness are not sufficiently considered (Kleynhans & Fourie 2014). Hence, this workshop concerns accessibility of all kinds of digital media and services. Besides dedicated assistive technologies, audio- and gesture-based interfaces are also of interest in this context, because they work without visual interfaces and can generate an innovative user experience for sighted as well as blind users. Some audio-based computer games are already designed as special kind of game for sighted and blind players (Collins 2013, Friberg & Gärdenfors 2008).
