Developing steady clicks: A method of cursor assistance for people with motor impairments
Abstract
Slipping while clicking and accidental clicks are a source of errors for mouse users with motor impairments. The Steady Clicks assistance feature suppresses these errors by freezing the cursor during mouse clicks, preventing overlapping button presses and suppressing clicks made while the mouse is moving at a high velocity. Evaluation with eleven target users found that Steady Clicks enabled participants to select targets using significantly fewer attempts. Overall task performance times were significantly improved for the five participants with the highest slip rates. Blocking of overlapping and high velocity clicks also shows promise as an error filter. Nine participants preferred Steady Clicks to the unassisted condition. If used in conjunction with existing techniques for cursor positioning, all of the major sources of clicking errors observed in empirical studies would be addressed, enabling faster and more effective mouse use for those who currently struggle with the standard mouse.
