Summary:An important part of natural, and therefore effective, communication is facial motion. The android Repliee Q2 should therefore display realistic facial motion. In computer graphics animation, such motion is created by mapping human motion to the animated character. This paper proposes a method for mapping human facial motion to the android. This is done using a linear model of the android, based on blendshape models used in computer graphics. The model is derived from motion capture of the android and therefore also models the android's physical limitations. The paper shows that the blendshape method can be successfully applied to the android. Also, it is shown that a linear model is sufficient for representing android facial motion, which means control can be very straightforward. Measurements of the produced motion identify the physical limitations of the android and allow identifying the main areas for improvement of the android design.
