Assessing the Pupil Dilation as Implicit Measure of the Sense of Embodiment in Two User Studies
conference paper
The aim of this paper is to explore pupil diameter as a novel way to help estimate the Sense of Embodiment (SoE) [8]. SoE can be defined as the ensemble of sensations that arise in conjunction with having and/or controlling a surrogate body or effector (such as a robotic device, a virtual avatar, or a mannequin) [1, 31]. SoE is considered an important aspect in teleoperation settings, where operators control a device, such as a robotic arm, at a different location by using their own arm and simultaneously viewing the robotic arm through an HMD. SoE can be characterized by three components: 1) the sense of ownership, i.e. the feeling of self-attribution to an external object or device [1, 2]. 2) The sense of agency, defined as the feeling of having motor, action and intention control over the surrogate effector [1, 4]. 3) The sense of self-location, referring to the volume of space where one feels located [1]. Usually, self-location and body-space coincide so that one feels self-located inside a physical body [4] (out-of-body experiences can be an exception [5]).
