Many touch based interactions provide limited opportunities for direct tactile feedback; examples include multi-user touch displays, augmented reality based projections on passive surfaces, and mid-air input. In this paper, we consider distal feedback, through vibrotactile stimulation on a smart-watch placed on the user’s non-dominant wrist, as an alternative feedback mechanism to interaction location vibrotactile feedback, under the user’s finger. We compare the effectiveness of interaction location feedback vs. distal feedback through a Fitts’s Law task completed on a smartphone. Results show that distal and interaction location feedback both reduce errors in target acquisition and exhibit statistically comparable performance, suggesting that distal vibrotactile feedback is a suitable alternative when interaction location feedback is not readily available.
