Typing Tutor: individualized tutoring in text entry for older adults based on input stumble detection

摘要

As older users adopt smartphones, they need to acquire new skills for interacting with touch-based devices. This paper describes the development of a support system, Typing Tutor, to improve text entry for older users in Japan transitioning from feature phones to smartphones. After confirming that older users are amenable to instructions (as opposed to trial and error, for example), and identifying instances and categories of "input stumbles," the authors developed and evaluated the Typing Tutor system.
