This article presents results of two pilot studies that investigated error behaviours with an unreliable in-air gesture recognizer. During the studies, users performed a small set of simple in-air gestures. In the first study, these gestures were abstract. The second study associated concrete tasks with each gesture. The error patterns in the two studies(More)
We present results of two pilot studies that investigated human error behaviours with an error prone in-air gesture recognizer.

Interestingly, the error patterns observed(More)
