“…The latter, instant feedback, can be categorised into changes in coloured joint points [22] or skeleton [5,18,38], virtual coaches placed around the learner's avatar [6,22] and translucent or coloured virtual coach avatar overlapping the learner's one [18,22,38]. Mirrors [1] and third-person viewpoints [16] have also been used to assist the learner to adjust their posture. To highlight the important postures that need to be matched, the keyframes from the pre-recorded movement of the virtual coach could be selected and presented to the learner [1].…”

Figure 1: Scenario with one actor jumping between several "agent avatars" and interacting with the user when necessary. (a) The user enters the scene and discovers three agent avatars. All three agent avatars are playing pre-recorded, loopable clips. Two of them portray customers while the third one acts as the barista. An actor, who is invisible to the user, is ready to take over any of the agent avatars and interact with the user. (b) The actor realizes that the participant intended to interact with agent avatar number 0, who is playing the role of a barista. Consequently, the actor plans to take control of that agent avatar and embody it to respond to and interact with the user. (c) The actor takes control of Avatar0 and is now interacting with the user. Meanwhile, all the other agent avatars continue to play their pre-recorded clips. (d) The actor releases control of Avatar0 and switches to another agent avatar to interact with the user. This creates the illusion that all three agent avatars were being controlled by real humans.

“…Within AR, avatarization was often explored to improve user posture awareness and spatial perception by providing a 3PP visualization. For example, Hamanishi et al [152] implemented an OST system providing an out-of-body viewpoint of the user rendered as an avatar animated in real time with motion capture. Soltani et al [163] provided a complete survey of similar types of applications, but it seems that AR examples of full-bodied live avatarization are rare.…”

Virtual self-avatars have been increasingly used in Augmented Reality (AR) where one can see virtual content embedded into physical space. However, little is known about the perception of self-avatars in such a context. The possibility that their embodiment could be achieved in a similar way as in Virtual Reality opens the door to numerous applications in education, communication, entertainment, or the medical field. This article aims to review the literature covering the embodiment of virtual self-avatars in AR. Our goal is (i) to guide readers through the different options and challenges linked to the implementation of AR embodiment systems, (ii) to provide a better understanding of AR embodiment perception by classifying the existing knowledge, and (iii) to offer insight on future research topics and trends for AR and avatar research. To do so, we introduce a taxonomy of virtual embodiment experiences by defining a "body avatarization" continuum. The presented knowledge suggests that the sense of embodiment evolves in the same way in AR as in other settings, but this possibility has yet to be fully investigated. We suggest that, whilst it is yet to be well understood, the embodiment of avatars has a promising future in AR and conclude by discussing possible directions for research.
