  Numerous accessibility features have been developed and included in consumer
operating systems to provide people with a variety of disabilities additional
ways to access computing devices. Unfortunately, many users, especially older
adults who are more likely to experience ability changes, are not aware of
these features or do not know which combination to use. In this paper, we first
quantify this problem via a survey with 100 participants, demonstrating that
very few people are aware of built-in accessibility features on their phones.
These observations led us to investigate accessibility recommendation as a way
to increase awareness and adoption. We developed four prototype recommenders
that span different accessibility categories, which we used to collect insights
from 20 older adults. Our work demonstrates the need to increase awareness of
existing accessibility features on mobile devices, and shows that automated
recommendation could help people find beneficial accessibility features.
