Presenters often screen-share slides over remote meetings as visual aids. Screen reader users however often do not have adequate ways to access slide content during presentations. To inform the design of more accessible interfaces, we ran a formative design workshop to elicit what screen reader users value during live screen-shared presentations, which are Prioritize Key Information, Reduce Cognitive Load, Provide Exploration Independence, Minimize Control Effort, and Encode Spatial Information. Based on these values, we created two prototypes that users experienced in a follow-up design probe. These interactions provide users control over what, when, and how slide elements are read out and introduce spatial audio separation between the presenter’s voice and screen reader audio. Participants found that a laptop-based prototype designed for the first four values significantly improved the accessibility of screen-shared content over existing tools, even with a presenter who was perceived to present materials accessibly. The importance of concurrent exploration is highlighted by participants’ frequent and diverse use of access to consume information complementary to the presenter, align focus, and understand information using alternative means. A phone-based prototype that encoded spatial information and greater exploration independence at the cost of increased cognitive load received mixed feedback, illustrating the balance between values that interaction design needs to strike. We conclude with insights and considerations for how the identified values and corresponding interactions can be used to improve the accessibility of screen-shared presentations.
