I have run a several studies with novel gestural interfaces over the last few years (touch and non-touch). I will discuss a recurring theme I have observed during every study: users misinterpreting feedback, and mis-applying what they should have learned. Interaction in a gestural interface is more ambiguous than in an interface with physical or software buttons. There is disagreement on what the "interaction" itself was between the human and the computer. I'll talk about what this means for the future of gestural interfaces, and especially how this affects Wizard-of-Oz studies.
