Cooperative gestures are gestures performed by multiple users to facilitate collaboration on large interactive surfaces, such as tabletops. While previous research suggested that such gestures enhance user experience, they overlooked important aspects of user experience and, in particular, the users’ sense of agency. This paper considers two types of cooperative gestures: (i) egalitarian, where both users have the same role, and (ii) hierarchical, where one user (the leader) leads the action, and the other user (the follower) follows the leader’s actions. In a user experiment, we evaluate these types of cooperative gestures by measuring the participants’ sense of agency using intentional binding and judgment of control. Results show a decrease in the sense of agency for the followers. By contrast, leaders and users with egalitarian roles maintained their agency at the implicit sensorimotor level. We conclude with “implications for design” of these findings.
