Abstract

Although a number of studies have reported that force
feedback gravity wells can improve performance in “pointand-click”
tasks, there have been few studies addressing
issues surrounding the use of gravity wells for multiple onscreen
targets. This paper investigates the performance of
users, both with and without motion-impairments, in a
“point-and-click” task when an undesired haptic distractor
is present. The importance of distractor location is studied
explicitly. Results showed that gravity wells can still
improve times and error rates, even on occasions when the
cursor is pulled into a distractor. The greatest improvement
is seen for the most impaired users. In addition to
traditional measures such as time and errors, performance is
studied in terms of measures of cursor movement along a
path. Two cursor measures, angular distribution and
temporal components, are proposed and their ability to
explain performance differences is explored.
