Co-authored with Nathaniel Rivers (Saint Louis University), “Ambient Captioning” responds to an ongoing call to expand accessibility by proposing that captioning should not only be the labor of the one who makes an address but also those who can be addressed as a way to help provide accessible entries for those who might not. In short, to make captioning leverage the wide distribution of attention to what might be considered ambient, we propose to make captioning an ambient practice. A primary aim for ambient captioning is to cultivate a shared capacity for captioning as an ethic of accessibility.
