<p>Actroid-SIT, a lifelike robot from Japanese firm Kokoro, hasn't received as much attention as her cousin Geminoid F, which happens to be a copy a real woman. But while Geminoid F is a teleoperated robot, Actroid-SIT can function autonomously, talking and gesturing while interacting with people. In fact, researchers have recently demonstrated how improvements to Actroid's behavior can make it look smarter and more expressive than your average android.</p><p>Actroid now makes eye contact and gestures in the direction of a person trying to speak to her, allowing it to adeptly handles crowds of people. To develop the new behavior, researchers from Nara Institute of Science and Technology studied how individuals and groups interacted with the robot. Based on their observations, they focused on two new features, which they call "interruptibility" and "motion parameterization," hoping to improve human-robot interaction.</p><p>The first feature lets Actroid-SIT to handles interruptions in a graceful way. In their human-robot interaction experiments, the researchers noted that interruptions occurred about 26 percent of the time. For example, the human switched topics or handed off the speaking role to someone else. The problem is that despite these interruptions, the robot would obliviously carry on until it finished its spiel. Not very socially elegant!</p><p>With the new "interruptibility" feature, the robot can immediately end its current topic and elegantly transition to the new response. Those few seconds countpeople interacted significantly longer with the robot when it was interruptible.</p><p><a href="http://spectrum.ieee.org/automaton/robotics/humanoids/japanese-robot-actroid-sit">Keep reading...</a></p>
