Towards a Common Framework for Mediated Embodiment
Mediated embodiment is the technologically generated illusion of replacing a person’s body with an avatar body. Virtual reality is the most representative technology of mediated embodiment. However, other forms of embo- diment are emerging and need to be examined. The inclusion of all mediated embodiment technologies under a common paradigm would more readily facilitate their study. Here, a unified conceptual framework of mediated embodiment is presented, which integrates robot embodiment as part of the phenomenon, and allows the in- clusion under the same umbrella of embodiment technologies that might emerge in the future. The minimum conditions necessary to induce the embodiment illusion, as well as the technical principles used to create this illusion, are discussed. Furthermore, it is suggested that mediated embodiment technologies can be regarded as tools that increase human capabilities in four directions: embodiment of a new self; expansion of traveling capa- bilities; expansion of body capabilities; and the reach of immortality. The principal research conducted in the field of mediated embodiment is explained in connection to these categories. The framework is expected to contribute to creating awareness of the commonalities of mediated embodiment technologies among the different research communities that work with mediated embodiment.
