“…This was demonstrated in a VR basketball application in which motor behavior were closer to reality in 3PP than in 1PP (speed at moment of release closer to real throw than in 1PP) [4]. For HMD, it was shown that a short training is sufficient for subjects to perform distance estimation in 1PP and 3PP with similar precision [17]. The question is therefore to know if these benefits of 3PP can be exploited without detrimental consequences on the immersion and the ability to embody an avatar.…”

“…the experienced location of the self. From a more practical standpoint, changing the perspective from first (1PP) to third person perspective (3PP) allows taking a new and potentially more informative point of view within a VR application (such as for training [3,17,4]). The problem is that 3PP breaks the natural condition in which subjects experience self-location with respect to their real bodies, and might consequently lower the sense of embodiment and the sense of presence.…”

Third Person Perspective (3PP) viewpoints have the potential to expand how one perceives and acts in a virtual environment. They offer increased awareness of the posture and of the surrounding of the virtual body as compared to First Person Perspective (1PP). But from another standpoint, 3PP can be considered as less effective for inducing a strong sense of embodiment into a virtual body. Following an experimental paradigm based on full body motion capture and immersive interaction, this study investigates the effect of perspective and of visuomotor synchrony on the sense of embodiment. It provides evidence supporting a high sense of embodiment in both 1PP and 3PP during engaging motor tasks, as well as guidelines for choosing the optimal perspective depending on location of targets.

“…Recent results suggest an advantage of third-over first-person perspectives in a ball-catching task (Salamin, Tadi, Blanke, Vexo, & Thalmann, 2010). Indeed, it was found that first-person views involve other neural processes than do third-person perspectives (David et al, 2006;Kockler et al, 2010;Vogeley et al, 2004).…”

Augmented visual, auditory, haptic, and multimodal feedback in motor learning: A review

et al. 2012

It is generally accepted that augmented feedback, provided by a human expert or a technical display, effectively enhances motor learning. However, discussion of the way to most effectively provide augmented feedback has been controversial. Related studies have focused primarily on simple or artificial tasks enhanced by visual feedback. Recently, technical advances have made it possible also to investigate more complex, realistic motor tasks and to implement not only visual, but also auditory, haptic, or multimodal augmented feedback. The aim of this review is to address the potential of augmented unimodal and multimodal feedback in the framework of motor learning theories. The review addresses the reasons for the different impacts of feedback strategies within or between the visual, auditory, and haptic modalities and the challenges that need to be overcome to provide appropriate feedback in these modalities, either in isolation or in combination. Accordingly, the design criteria for successful visual, auditory, haptic, and multimodal feedback are elaborated.

“…Salamin et al [2010] found that performance on a ball catching task after augmented reality training from 3PP (depicting their own body with a video camera) was improved compared to 1PP training. Related work with the control of teleoperated robots also suggests that changes in perspective of the robot still preserve body ownership [Ogawa et al 2012].…”

Figure 1: Static third-person avatar, 6 m in front of the viewer (left). Third-person self-avatar animated based on the viewer's movements, 6 m in front of the viewer (middle). Targets visible to the viewer, one of which the viewer is asked to point to from the avatar's location (right). AbstractThe use of third-person self-avatars has become common in nonimmersive virtual environments, due in part to the advantages of seeing a full body while moving around in space. However, little research has investigated how third-person self-avatars can benefit task performance in immersive virtual environments (IVEs). This paper explores a procedure that may enhance user ability to act in an IVE from the point of view of a self-avatar projected in front of the viewer. Such abilities could be crucial in applications such as remote operator control, when a third person view is necessary or is the only view available. We conducted an experiment to assess the role of dynamic visual-motor and haptic feedback with a third-person avatar on a user's ability to point to remembered targets from the location of the avatar. The dynamic condition was compared within-subjects to a static condition in which the user's movements were not tracked with the avatar but the same task was required. Overall, participants were relatively good at pointing to targets from the location of the avatar. However, participants in the dynamic condition showed pointing performance that corresponded more closely to the avatar's location than was the case in the static condition. Subjective reports of bodily self-perception were also included and showed increased self-identification, presence, and agency in the dynamic compared to the static condition.
