Gesture-based screen readers like VoiceOver or TalkBack provide visually impaired users with a means to interact with digital content. However, there is a significant lack of both strategies and resources for teaching the use of these screen readers, and standardized teaching guidelines are notably absent. Furthermore, there is no free, universally designed, and accessible app for practicing gestures in mobile screen readers. This study aims to identify best practice strategies for teaching and practicing the use of gesture-based screen readers among visually impaired users, based on observations from an IT course directed at visually impaired individuals. Moreover, we present common challenges related to usability, attitudes, emotions, technical aspects, and user guidance and education, as well as key traits and facilitators for learning gesture-based screen readers. Lastly, we assess the feasibility of an app to practice gestures and propose a framework for a gesture practice app to enhance user accuracy and patience.
