“…Our proof-of-concept prototype (Sand et al, 2015) enables users to touch and feel virtual 3D objects without the need for wearable devices. A superwide field-of-view (FOV) optical design for VR glasses (Rakkolainen et al, 2016;Rakkolainen et al, 2017b) can cover even the full human FOV. Recently we have also experimented with extending the FOV of a VR viewing device (Rakkolainen et al, 2017a) and providing visual feedback for a smart glass user directly to the retinasurpassing the eye and its lens (Koskinen et al, 2017).…”

Human augmentation is a field of research that aims to enhance human abilities through medicine or technology. This has historically been achieved by consuming chemical substances that improve a selected ability or by installing implants which require medical operations. Both of these methods of augmentation can be invasive. Augmented abilities have also been achieved with external tools, such as eyeglasses, binoculars, microscopes or highly sensitive microphones. Lately, augmented reality and multimodal interaction technologies have enabled non-invasive ways to augment human.In this article, we first discuss the field and related terms. We provide relevant definitions based on the present understanding of the field. This is followed by a summary of existing work in augmented senses, action, and cognition. Our contribution to the future includes a model for wearable augmentation. In addition, we present a call for research to realize this vision. Then, we discuss future human abilities. Wearable technologies may act as mediators for human augmentation, in the same manner as eyeglasses once revolutionized human vision. Non-invasive and easy-to-use wearable extensions will enable lengthening the active life for aging citizens or supporting the full inclusion of people with special needs in society, but there are also potential problems. Therefore, we conclude by discussing ethical and societal issues: privacy, social manipulation, autonomy and side effects, accessibility, safety and balance, and unpredictable future.

“…It was observed during some of the SbS tests in the VR, although not measured directly, that the test subject either tried to fall back slightly behind the pacer, so that the pacer was within their sight, or turned their head towards the pacer. This intermittent behaviour might have been the result of the limited horizontal field of view (FoV) provided by the HMD, confined to around 90 degrees [ 100 ]. In comparison, the unobstructed FoV of an average human spans approximately 200 degrees in the horizontal direction [ 101 ], which is significantly more than that of the HMD.…”

In comparison, the unobstructed FoV of an average human spans approximately 200 degrees in the horizontal direction [101], which is significantly more than that of the HMD. It was previously shown that limiting horizontal FoV can impact one's perception of space [102], which might have led to more conscious stepping behaviour.…”

Little information is currently available on interpersonal gait synchronization in overground walking. This is caused by difficulties in continuous gait monitoring over many steps while ensuring repeatability of experimental conditions. These challenges could be overcome by using immersive virtual reality (VR), assuming it offers ecological validity. To this end, this study provides some of the first evidence of gait coordination patterns for overground walking dyads in VR. Six subjects covered the total distance of 27 km while walking with a pacer. The pacer was either a real human subject or their anatomically and biomechanically representative VR avatar driven by an artificial intelligence algorithm. Side-by-side and front-to-back arrangements were tested without and with the instruction to synchronize steps. Little evidence of spontaneous gait coordination was found in both visual conditions, but persistent gait coordination patterns were found in the case of intentional synchronization. Front-to-back rather than side-by-side arrangement consistently yielded in the latter case higher mean synchronization strength index. Although the mean magnitude of synchronization strength index was overall comparable in both visual conditions when walking under the instruction to synchronize steps, quantitative and qualitative differences were found which might be associated with common limitations of VR solutions.

“…Design elements for visual senses consist of a field of view (FOV), field of regard (FOR), visual illusions, color, depth, scale, and framing. Current HMD's provide have 100-degree horizontal and 110-degree vertical FOV (Rakkolainen et al, 2017), and 360-degrees horizontal and vertical FOR (Jerald, 2016). Thus, the current VR technology allows the player to look in all directions in the virtual environment by turning his head.…”

Virtual reality has great potential for immersive experiences that is not available in other mediums. Thus, it has a significant place in the entertainment and the game industry. However, creating a well-designed immersive experience can be extremely complicated due to the replacement of human perception from the real-world to an isolated virtual world. Understanding the essentials of virtual reality (VR) experiences and game design principles is necessary for designing an immersive VR game. Although there are many differences in design elements of VR games according to the experience that is wanted to be given to the player, many games also have common elements. In the line of this view, a guideline is aimed to be framed for VR game designers in the current study. For this purpose design pillars of VR experiences and game design principles were reviewed, and five VR games were analyzed. Games are highly plastic mediums that can be adapted to any environment and technology. Many game types have a close relationship in terms of game elements and design. However, the implementation of game elements from other mediums to the VR medium is challenging. Therefore, game design principles should be well-comprehended and implemented to the VR medium by considering the existed technology. Virtual reality takes the player and put him in a new virtual world. In this world, everything should be designed to be easily perceivable by the player. Thus, the human perception was reviewed as one of the design pillars. Virtual reality also offers an interactive experience that allows the user to affect the world. Like in traditional video games, players can interact and navigate in the virtual world. Therefore, interaction and navigation were reviewed as two other design pillars. Based on the reviewed design pillars, five VR games were analyzed. Then, a VR game design guideline is proposed based on common game design elements in those games
