Abstract

support remote collaboration. But, their small form-factor

may impact the effectiveness of the visual feedback channel

often used to help users maintain an awareness of their

partner’s activities during synchronous collaborative tasks.

We investigated how visual and tactile feedback affects

collaboration on mobile devices, with emphasis on spatial

coordination in a shared workspace. From two user studies,

our results highlight different benefits of each feedback

channel in collaborative handheld systems. Visual feedback

can provide precise spatial information for collaborators,

but degrades collaboration when the feedback is occluded,

and sometimes can distract the user’s attention. Spatial

tactile feedback can reduce the overload of information in

visual space and gently guides the user’s attention to an

area of interest. Our results also show that visual and tactile

feedback can complement each other, and systems using

both feedback channels can support better spatial

coordination than systems using only one form of feedback.
