Multi-layered interdependency?: the role of assistive technologies for knowledge workers with visual impairment

Knowledge work has become unimaginable without information and communication technology. Assistive technology (AT) is intended to provide knowledge workers with visual impairments (theoretically) the same access to the different "Main-stream"-technology applications which all colleagues commonly use for the completion of their work tasks. Based on ethnographic data, this article shows that knowledge workers with visual impairments repeatedly encounter obstacles and interdependencies, in which AT plays a decisive and multifaceted role between dis-/ and ability. We furthermore argue that interdependence in the sense of Bennett el al. (2018) can benefit from a more detailed, two-staged differentiation of the component "environment" to sharpen the analytical perspective on AT for the area of knowledge work.
