Being an Avatar "for Real": A Survey on Virtual Embodiment in Augmented Reality.
IEEE Transactions on Visualization and Computer Graphics
|July 26, 2021
Summary
Virtual self-avatars in Augmented Reality (AR) are being explored for embodiment. Research suggests embodiment perception in AR mirrors Virtual Reality (VR), with promising future applications.
Area of Science:
- Human-Computer Interaction
- Virtual Reality and Augmented Reality
- Cognitive Science
Background:
- Augmented Reality (AR) increasingly incorporates virtual self-avatars, yet their embodiment perception remains under-explored.
- Understanding avatar embodiment in AR is crucial for applications in education, communication, entertainment, and medicine.
- Existing research primarily focuses on Virtual Reality (VR) embodiment, with limited investigation into AR contexts.
Approach:
- This article reviews existing literature on virtual self-avatar embodiment within Augmented Reality (AR).
- A taxonomy of virtual embodiment experiences is introduced, defining a 'body avatarization' continuum.
- The review aims to classify knowledge, identify challenges, and suggest future research directions.
Key Points:
- The sense of embodiment for virtual self-avatars appears to evolve similarly in AR as in VR.
- Implementing AR embodiment systems presents unique technical and perceptual challenges.
- The classification of AR embodiment experiences provides a framework for understanding user perception.
Conclusions:
- While not fully understood, avatar embodiment in AR shows significant potential across various fields.
- Further research is needed to fully investigate and understand embodiment perception in AR.
- Future directions include exploring advanced AR embodiment techniques and their impact on user experience.

The Sense of Self: Reflected Self-Appraisal and Social Comparison
According to Charles Cooley, we base our image on what we think other people see (Cooley 1902). We imagine how we must appear to others, then react to this speculation. We don certain clothes, prepare our hair in a particular manner, wear makeup, use cologne, and the like—all with the notion that our presentation of ourselves is going to affect how others perceive us. We expect a certain reaction, and, if lucky, we get the one we desire and feel good about it. But more than that, Cooley...
Social Foundations of Self IV: Self in Digital Communication
Since the early 2000s, computer-mediated communication (CMC) has grown rapidly, playing a crucial role in self-development. A key distinction between CMC and real-life interactions is the lack of a physically present partner. This absence makes non-verbal cues such as facial expressions, body language, and paralinguistic signals unavailable in CMC platforms like email, instant messaging, or social media. The lack of these cues can create ambiguity and complicate how feedback is interpreted.The...
