2010 The Effect of Gesture on Collaboration with an Autonomous Robot by Kevin O’Brien Joel Sutherland This report represents the work of two WPI undergraduate students submitted to the faculty as evidence of completion of a degree1 requirement. WPI routinely publishes these reports on its web site without editorial or peer review. The Effect of Gesture on Collaboration with an Autonomous Robot A Major Qualifying Project Report Submitted to the Faculty of the WORCESTER POLYTECHNIC INSTITUTE in partial fulfillment of the requirements for the Degree of Bachelor of Science by _________________________ Kevin O’Brien (Computer Science) _________________________ Joel Sutherland (Robotics Engineering) Approved: ____________________________ Prof. Charles Rich, Major Advisor 2 Abstract The goal of this project was to study the effect of robot gestures on the quality of collaboration between an autonomous robot and a human. We conducted a spoken-language human-robot interaction study with 26 participants which showed that adding robot head turns (to make eye contact with the human) and robot arm gestures (to point toward task-related objects) improved the human's perception of the robot's interaction skills and role as a good collaborator. These results have important implications for the design of human-robot interactions in general.

For robots to do this effectively, they will need to communicate with humans and be able
