Summary:
Goal: Inexact & inattentive interaction. interaction that does not require visual attention and does not disrupt the current activity.

Whack gestures - a set of gestures which are combinations of whack/ tap and wiggle/ shake. An adhoc recognition engine is set up to recognize the gestures. A user study with 11 people was performed to check the accuracy of the recognition.

Discussion:
I was totally taken back by the evaluation. I was expecting qualitative evaluation of the system as such user experience evaluation. I did not expect a recognizer accuracy evaluation. It would have been more interesting if they had evaluated the user experience given a certain scenario.

  1. I agree, the user study should have been conducted under normal everyday conditions to be objective.

  2. That is true. It is pointless to develop something that people won't use. More studies were needed.
