Objective evaluation of mechanical expressiveness in android and human faces

A scientist from the Graduate School of Engineering at Osaka University proposed a numerical scale to quantify the expressiveness of robotic android faces. By focusing on the range of deformation of the face instead of the number of mechanical actuators, the new system can more accurately measure how much robots are able to mimic actual human emotions. This work, published in Advanced Robotics, may help develop more lifelike robots that can rapidly convey information.
