The goal of this paper is to analyse a method of validating a subset of gestures to be used as elements of a HCI interface. We investigate the applicability of LDA for gesture data dimensionality reduction. An Gesture mutual separability analysis of a diverse dataset of 22 natural gestures captured with two motion-capture devices is provided. Fisher criterion is used to produce measures of class separability and class overlap.
