We manipulate equipment naturally as an extension of physical ability. However, it is unclear whether we can transform supernumerary body parts to our body image to use the equipment as a similar body parts. So, this study suggests that ownership is formed by the simultaneity of visual and tactile stimulation, and that this perception of ownership is important to form the body image. In addition, we propose that if the equipment appears to be extended continuously from our body and ownership of the equipment occurs, then the body image will be transformed to include the equipment. Therefore, in this study, the equipment was arranged to appear as extending from the body, and visual and tactile stimulation were used to elicit ownership of the equipment. The results confirmed that body image was transformed to include the equipment. Furthermore, this suggested that it is possible to incorporate equipment into one's body image, and that we could use the equipment as a supernumerary our own body-part.
