The Internet has become an important tool for many aspects of modern life. However, some individuals may experience challenges accessing the Internet if they have difficulty accurately controlling a pointing device. These pointing problems can vary in severity and frequency and may be caused by a motor impairment, limited hand dexterity, or fatigue. We believe that adaptive user interfaces (AUIs) offer a unique solution to detect and accommodate an individual's current pointing behavior. While past work has explored the implementation of detecting pointing challenges and designing adaptations, little has been done to understand how this population would like to interact with this software. In this paper, we present the results from participatory design sessions with older and younger adults that highlight their preferences for novel AUIs. We found diverse preferences and attitudes towards how AUIs notify a user of their current performance, and how they should adapt to pointing behavior. We present these diverse opinions as three personas that can be applied to future design of any AUI.
