Performance on a Natural User Interface Task is Correlated with Higher Gesture Production

The study examined whether the individual differences of gesture production and attitudes toward gesturing were related to performance on a gesture-based natural user interface. Participants completed a lesson using gesture interactions and were measured on how long it took to complete the lesson, their reported mental effort, and how much they learned during the lesson. The Brief Assessment of Gestures survey was used to determine different dimensions of a participant’s predisposition to gesture, with four subscales: Perception, Production, Social Production, and Social Perception. Only an individual’s propensity to produce gestures was related to higher learning outcomes from the computer-based lesson.
