Assessing Alternative Text Presentation and Tablet Device Usage for Low Vision Leisure Reading

摘要

We conducted 3 studies to learn about elements of satisfaction for leisure reading in low vision. Study 1 focused on alternative reading formats such as scrolling text and rapid serial visual presentation (RSVP). Study 2 explored use and satisfaction with alternative formats over time using a tablet device. Study 3 meant to assess prevalence and perceptions of tablet devices as low vision aids for sustained reading. Nine low vision participants used a tablet to read with three presentation types (Page, Scroll, Modified RSVP) over a three-week period. Study 3 involved surveys administered to 73 participants 1-3 months after a vision consultation with a low vision professional in which multiple options for reading devices were demonstrated. Studies 1 and 2 point to the need to emphasize personal preferences and satisfaction with reading devices, in addition to reading performance. Alternative presentations may be beneficial to certain people with low vision, especially those with difficulties navigating lines of text and controlling eye movements. Study 3 showed that participants were generally satisfied with their reading aids and used them frequently at a 1-3 month follow up. Participants appeared interested in tablets as a reading method, despite many having little to no experience with them prior to the study. Barriers to using a tablet were primarily cost and lack of familiarity.
