“…Present-day VR, however, is a brilliant new medium that exceeds illusion and brings about tangible results in reality with unlimited potential for large-scale application in art, entertainment, relaxation, learning, exercise, training, and treatment or therapy. VR visualizes not only events but also psychological conditions and personalized perceptions [ 217 , 218 , 219 , 220 ], induces a sense of ownership [ 221 , 222 ] and of presence [ 223 , 224 , 225 , 226 , 227 ], offers immersion [ 228 ], and renders the self in different reality modes, such as being represented by avatar or having a different gender [ 229 , 230 ]. It also influences physical sensations in interventions, such as pain management [ 231 , 232 ] or stress and anxiety reduction [ 233 ]; induces necessary emotions, such as empathy [ 234 ]; or aims at achieving higher goals, such as self-development [ 235 ].…”

Virtual Reality for Neurorehabilitation and Cognitive Enhancement

Our access to computer-generated worlds changes the way we feel, how we think, and how we solve problems. In this review, we explore the utility of different types of virtual reality, immersive or non-immersive, for providing controllable, safe environments that enable individual training, neurorehabilitation, or even replacement of lost functions. The neurobiological effects of virtual reality on neuronal plasticity have been shown to result in increased cortical gray matter volumes, higher concentration of electroencephalographic beta-waves, and enhanced cognitive performance. Clinical application of virtual reality is aided by innovative brain–computer interfaces, which allow direct tapping into the electric activity generated by different brain cortical areas for precise voluntary control of connected robotic devices. Virtual reality is also valuable to healthy individuals as a narrative medium for redesigning their individual stories in an integrative process of self-improvement and personal development. Future upgrades of virtual reality-based technologies promise to help humans transcend the limitations of their biological bodies and augment their capacity to mold physical reality to better meet the needs of a globalized world.

“…Our results are similar to those of Lugrin et al 31 who reported no significant differences in self‐reported body ownership between all three avatars when examining a human, robot, and block‐man avatars. Jo et al 32 also investigated three self‐avatar body types for inducing body ownership, finding that the cartoon‐like semblance of the actual participant elicited the most body ownership, when compared to a realistic self‐avatar and a cartoon‐like character in a different outfit. Considering their results, it is possible that none of our self‐avatars elicited body ownership, as none bore any semblance to any participants.…”

Eye fixations and electrodermal activity during low‐budget virtual reality embodiment

As motion-sensing devices become more accessible to consumers, it is important to understand how users experience embodiment when using these devices. In our 3 × 2 between-groups study, we explored eye fixations and electrodermal activity (EDA) in order to more objectively understand potential interaction effects between the self-avatar body, and the presence of a mirror within the context of low-budget embodiment. We developed six experimental conditions concerning Body (human, mannequin, and zombie self-avatars) and Mirror (mirror and no mirror) factors, and presented participants with a virtual environment in which they could control their self-avatars by using HTC Vive controllers and trackers. In addition to eye fixations and EDA, we assessed self-reported data concerning body ownership, agency, self-location, as well as enjoyment of the experience. Our results suggest that the Body may have been more influential in eliciting body ownership than the Mirror, and that an interaction effect between Gender and Body may influence eye gaze behavior. Additionally, female participants reported significantly higher agency than males. We consider logical next steps for similar research which might elaborate upon our findings.

“…However, the work on appearance of the hands and arms also suggests that more realism may be counterproductive (e.g. [6].). We also note that the hands only condition is not significantly different than the no avatar condition.…”

“…They found that each avatar generated a high level of ownership, but that the humanoid avatar was slighly lower [9]. Similarly, Jo et al showed that a faithful reproduction of the participant's hand solicited a lower body ownership than a cartoony avatar [6]. Argelaguet et al showed that participants had a higher sense of ownership of a virtual hand that mapped directly to their real hand [1].…”

Avatar Type Affects Performance of Cognitive Tasks in Virtual Reality

Current consumer virtual reality applications typically represent the user by an avatar comprising a simple head/torso and decoupled hands. In the prior work of Steed et al. it was shown that the presence or absence of an avatar could have a significant impact on the cognitive load of the user. We extend that work in two ways. First they only used a fullbody avatar with articulated arms, so we add a condition with hands-only representation similar to the majority of current consumer applications. Second we provide a realworld benchmark so as to start to get at the impact of using any immersive system. We validate the prior results: real and full body avatar performance on a memory task is significantly better than no avatar. However the hands only condition is not significantly different than either these two extremes. We discuss why this might be, in particular we discuss the potential for a individual variation in response to the embodiment level. CCS CONCEPTS• Human-centered computing → Virtual reality.
