Summary: Many older adults are interested in smartphones. However most of them
encounter difficulties in self-instruction and need support. Text entry, which
is essential for various applications, is one of the most difficult operations
to master. In this paper, we propose Typing Tutor, an individualized tutoring
system for text entry that detects input stumbles and provides instructions. By
conducting two user studies, we clarify the common difficulties that novice
older adults experience and how skill level is related to input stumbles. Based
on these studies, we develop Typing Tutor to support learning how to enter text
on a smartphone. A two-week evaluation experiment with novice older adults
(65+) showed that Typing Tutor was effective in improving their text entry
proficiency, especially in the initial stage of use.
