Adaptive Click and Cross: Adapting to Both Abilities and Task to Improve Performance of Users With Impaired Dexterity

Adaptive Click-and-Cross, an interaction technique for computer users with impaired dexterity. This technique combines three "adaptive" approaches that have appeared separately in previous literature: adapting the user's abilities to the interface (i.e., by modifying the way that the cursor works), adapting the user interface to the user's abilities (i.e., by modifying the user interface through enlarging items), and adapting the user interface to the user's task (i.e., by moving frequently or recently used items to a convenient location). Adaptive Click-and-Cross combines these three adaptations to minimize each approach's shortcomings, selectively enlarging items predicted to be useful to the user while employing a modified cursor to enable access to smaller items.
