In a meta-analysis of 43 studies, we examined the effects of multimodal feedback on user
performance, comparing visual-auditory and visual-tactile feedback to visual feedback …

Most work on the usability of touchscreen interaction for people with motor impairments has
focused on lab studies with relatively few participants and small cross-sections of the …

We present a novel method of dynamic CD gain adaptation that improves target acquisition
for users with motor impairments. Our method, called the Angle Mouse, adjusts the mouse …

Computer users with motor impairments face major challenges with conventional mouse
pointing. These challenges are mostly due to fine pointing corrections at the final stages of …

This paper examines how multimodal feedback assists small-target acquisition in graphical
user interfaces. All combinations of three feedback modes are analysed: non-speech audio; …

We present Surfpad, a pointing facilitation technique that does not decrease target distance
or increase target width in either control or display space. This new technique operates …

We present a new method of predicting the endpoints of mouse movements. While prior
approaches to endpoint prediction have relied upon normative kinematic laws, regression …

Prior research shows that people with motor impairments face considerable challenges
when using conventional mice and trackballs. One challenge is positioning the mouse …

Previous studies have defined a new type of impairment in which an able-bodied user's
behaviour is impaired by both the characteristics of a device and the environment in which it …
