This paper reviews recent works on high-fidelity human-like virtual avatars (e.g. high visual and motion fidelity) and discusses the critical question——“Is high-fidelity a positive choice for virtual avatars to achieve better interactions in HCI”. Furthermore, we summarise current technical approaches to developing those virtual avatars. We investigate the advantages and disadvantages of high-fidelity virtual avatars in different areas focusing on addressing the effect of motion, especially the upper body. Research shows that high-fidelity is a positive choice for virtual avatars, although it may depend on the application.

Affective Computing and the Road to an Emotionally Intelligent Metaverse

“…Transcending the uncanny valley requires researchers to delve into refining avatar design, aiming to achieve a closer resemblance to humans while still being well-received by users [161]. This may involve meticulous adjustments to facial features, body proportions, attire, and other visual elements [162]. Furthermore, investigating innovative animation techniques that emulate human movement patterns can contribute to a more genuine and lifelike user experience [163].…”
