Abstract
Abstract. The effect of multiple haptic distractors on target selection performance
was examined in terms of times to select the target and the associated cursor
movement patterns. Two experiments examined: a) The effect of multiple
haptic distractors around a single target and b) the effect of inter-item spacing
in a linear selection task. It was found that certain target-distractor arrangements
hindered performance and that this could be associated with specific, explanatory
cursor patterns. In particular, it was found that the presence of distractors
along the task axis in front of the target was detrimental to performance,
and that there was evidence to suggest that this could sometimes be associated
with consequent cursor oscillation between distractors adjacent to a desired
target. A further experiment examined the effect of target-distractor spacing
in two orientations on a user’s ability to select a target when caught in the
gravity well of a distractor. Times for movements in the vertical direction were
found to be faster than those in the horizontal direction. In addition, although
times for the vertical direction appeared equivalent across five target-distractor
distances, times for the horizontal direction exhibited peaks at certain distances.
The implications of these results for the design and implementation of haptically
enhanced interfaces using the force feedback mouse are discussed.
