Biases and interaction effects in gestural acquisition of auditory targets using a hand-held device

Abstract

A user study explored bias and interaction effects in an auditory target tracking task using a hand-held gestural interface device for musical sound. Participants manipulated the physical dimensions of pitch, roll, and yaw of a hand-held device, which were mapped to the sound dimensions of musical pitch, timbre, and event density. Participants were first presented with a sound, which they then had to imitate as closely as possible by positioning the hand-held controller. Accuracy and time-to-target were influenced by specific sounds as well as pairings between controllers and sounds. Some bias effects in gestural dimensions independent of sound mappings were also found. © 2011 ACM.
