Understanding how users can extend their bodies to control avatars can help to make the avatar control and interaction more intuitive and engaging. This paper investigates how multisensory stimuli in a virtual reality environment can contribute to the experience of owning and controlling an extended humanoid avatar with a set of virtual wings. We tested three conditions: visuomotor stimuli, visuomotor and visuotactile stimuli combined and a control condition with only visuoproprioceptive feedback. Results show that visuo-motor feedback was necessary for establishing agency and body-ownership of the wings, and also proved to be better for task performance than in combination with visuotactile feedback. Visuotactile feedback, on the other hand, significantly enhanced body-ownership of the wings, and agency according to questionnaire ratings.
