Virtual reality (VR) allows us to embody other identities using virtual humans, known as avatars. The appearance of these avatars can significantly influence the behavior of users in a virtual environment, known as Proteus Effect (Yee and Bailenson, 2007). Studies show that in this way, not only do users’ behaviors adapt to the avatar’s appearance, but even their internal body image can adapt to the altered virtual body weight if users felt embodied in the avatar (Turbyne et al., 2021). Can the feeling of altered body weight be further enhanced if one’s virtual body not only changes in visible body volume, but it also feels heavier?

Goal

Our goal is to find out whether a slowed down movement of the virtual body’s limbs can enhance the effect of embodying a heavier avatar and vice versa. For this purpose, we want to manipulate the motion velocity of the users’ virtual body and adapt it to the (virtual) body weight of the avatar.
