Abstract
Robotic modular interfaces, increasingly studied in Human-Computer Interaction, offer assistance to support users in their tasks. However, this assistance can harm the sense of agency (i.e., feeling of control), leading to non-use of the interface or a diminishing sense of responsibility regarding the consequences of users' actions. The impact of robotic modular interface assistance, during a cooperative task, on the user's sense of agency has not yet been studied. In this article, we propose to remedy this through the use of swarm robotic interfaces. We focus on nine levels of assistance, varying system autonomy and module coordination. Our study shows that: (1) the higher the autonomy, the lower the sense of agency, (2) coordination seems to have an impact on the sense of agency, and (3) three types of sense of agency emerge depending on the coordination of the modules.
