“…Participant 9 said "I think arm avatar was sufficient for this experiment; however, I preferred to interact with the body avatar because it felt like I was interacting with a real human." These results were similar to those reported by Yoon, in which participants preferred the body avatar more than the hand avatar or upper body avatar and disliked the hand avatar the most, owing to it not having a body [32]. Participant 2 further mentioned that the motion of the "Body" avatar, including bobbing (body moving up and down during each step) and lunging (moments of forwarding acceleration, sometimes associated with the forward thrust of taking each step), made the avatar more realistic.…”

“…To test the five hypotheses, we conducted a within-participant design experiment with a three-level independent variable "body representation level": "Body" [1,20,32], "Hand + Arm" [21], and "Hand only" [1,11,19,37]. Further, a comparative analysis among these three conditions was performed.…”

“…The results indicated that the body-shaped avatar increased the social presence of the interlocutor, and that participants felt they were interacting with a real person when interacting with the body-shaped avatar [1]. Yoon suggested that, in an AR-based remote collaboration system, a realistic whole-body avatar had a higher social presence than a hand-only avatar [32].…”

“…Additionally, although some researchers have investigated the effects of body representation level on social presence in remote collaboration [32], insufficient research exists regarding other aspects relating to manufacturing, such as efficiency, performance, workload, usability, and preference. To this end, in this study, we compared three avatars with different body representation levels, which have been used in remote collaboration/instruction systems: avatar with whole body [1,20,32], avatar with hand and arm [21], and avatar with only hand [1,11,19,37]. Furthermore, we investigated the influence of these avatars with different body representation levels on the quality of remote instruction.…”

In manufacturing, augmented reality (AR)-based remote instruction systems, which enable workers to receive instructions from an avatar, are widely used. In this study, we developed such a system and investigated the effect of the body representation level of the avatar on the quality of AR-based remote instruction. Drawing on the avatar designs of previous works, three different avatar designs (“Hand only”, “Hand + Arm”, and “Body”), representing three body representation levels, were created. In the experiment with a within-participant design, the avatar pointed at blocks sequentially and participants touched each block as soon as they identified it. The results of the experiment indicate that an AR-based remote instruction system with a “Body” avatar exhibits higher usability and can enable the participants to have a lower workload and higher efficiency.

“…H3: The better spatial communication expected with the streamed point-cloud avatar would increase the subjective feeling of presence, co-presence and social presence with this partner within the CVE. As suggested by previous research, a higher kinematic fidelity increases social presence [24,33,34,35].…”

Collaborative virtual environments allow remote users to work together in a shared 3D space. To take advantage of the possibilities offered by such systems, their design must allow the users to interact and communicate efficiently. One open question in this field concerns the avatar fidelity of remote partners. This can impact communication between the remote users, more particularly when performing collaborative spatial tasks. In this paper, we present an experimental study comparing the effects of two partner's avatars on collaboration during spatial tasks. The first avatar was based on a 2.5D streamed point-cloud and the second avatar was based on a 3D preconstructed avatar replicating the remote user movements. These avatars differ in their fidelity levels described through two components: visual and kinematic fidelity. The collaborative performance was evaluated through the efficacy of completing two spatial communication tasks, a pointing task and spatial guidance task. The results indicate that the streamed point-cloud avatar permitted a significant improvement of the collaborative performance for both tasks. The subjective evaluation suggests that these differences in performance can mainly be attributed to the higher kinematic fidelity of this representation as compared to the 3D preconstructed avatar representation. We conclude that, when designing spatial collaborative virtual environments, it is important to reach a high kinematic fidelity of the partner's representation while a moderate visual fidelity of this representation can suffice.
