3D Virtual Environment

The development of affordable virtual reality (VR) hardware represents a keystone of progress in modern software development and human-computer interaction. Despite the ready availability of robust hardware tools, there is presently a lack of video games or software in VR that demonstrates the gamut of unique and novel interfaces a virtual environment can provide. In this paper, we present a virtual reality video game which introduces unique user interface elements that can only be achieved in a 3D virtual environment. The video game, titled Wolf Hunt, provides users with a menu system that innovates on traditional interfaces with a virtual representation of a common item people interact with daily: a mobile phone. Wolf Hunt throws users into a procedurally generated world where they take the role of an individual escaping a wolf assailant. Deviating from traditional locomotion options in VR interfaces, such as teleportation, Wolf Hunt measures the displacement of hand-held VR controllers with the VR headset to simulate the natural action of running. Wolf Hunt provides an alternate interfacing solution for VR systems without having to conform to common 2D interface design schemes.

BACKGROUND In the last few years, the introduction of immersive technologies, especially virtual reality, into the gaming market has dramatically altered the traditional concept of video games. Given the unique features of virtual reality in terms of interaction and its ability to completely immerse the individual into the game, this technology should increase the propensity for video games to effectively elicit positive emotions and decrease negative emotions and anxiety in the players. However, to date, few studies have investigated the ability of virtual reality games to induce positive emotions, and the possible effect of this new type of video game in diminishing negative emotions and anxiety has not yet been tested. Furthermore, given the critical role of body movement in individuals’ well-being and in emotional responses to video games, it seems critical to investigate how body involvement can be exploited to modulate the psychological benefits of virtual reality games in terms of enhancing players’ positive emotions and decreasing negative emotions and anxiety. OBJECTIVE This within-subjects study aimed to explore the ability of commercial virtual reality games to induce positive emotions and diminish negative emotions and state anxiety of the players, investigating the effects of the level of body involvement requested by the game (ie, high vs low). METHODS A total of 36 young adults played a low body-involvement (ie, <i>Fruit Ninja VR</i>) and a high body-involvement (ie, <i>Audioshield</i>) video game in virtual reality. The Visual Analogue Scale (VAS) and the State-Trait Anxiety Inventory, Form-Y1 (STAI-Y1) were used to assess positive and negative emotions and state anxiety. RESULTS Results of the generalized linear model (GLM) for repeated-measures multivariate analysis of variance (MANOVA) revealed a statistically significant increase in the intensity of happiness (<i>P</i>&lt;.001) and surprise (<i>P</i>=.003) and, in parallel, a significant decrease in fear (<i>P</i>=.01) and sadness (<i>P</i>&lt;.001) reported by the users. Regarding the ability to improve anxiety in the players, the results showed a significant decrease in perceived state anxiety after game play, assessed with both the STAI-Y1 (<i>P</i>=.003) and the VAS-anxiety (<i>P</i>=.002). Finally, the results of the GLM MANOVA showed a greater efficacy of the high body-involvement game (ie, <i>Audioshield</i>) compared to the low body-involvement game (ie, <i>Fruit Ninja VR</i>), both for eliciting positive emotions (happiness, <i>P</i>&lt;.001; and surprise, <i>P</i>=.01) and in reducing negative emotions (fear, <i>P</i>=.05; and sadness, <i>P</i>=.05) and state anxiety, as measured by the STAI-Y1 (<i>P</i>=.05). CONCLUSIONS The two main principal findings of this study are as follows: (1) virtual reality video games appear to be effective tools to elicit positive emotions and to decrease negative emotions and state anxiety in individuals and (2) the level of body involvement of the virtual video game has an important effect in determining the ability of the game to improve positive emotions and decrease negative emotions and state anxiety of the players.

The Cost

What kind of world do ems see? We have several reasons to expect ems to usually experience simulated “virtual” realities. First, compared with ordinary humans, it is easier to fully immerse ems in computer-generated virtual realities. One could feed computed inputs into an em’s emulated eyes, ears, nose, fingers, etc., and take outputs from that em’s emulated arms, legs, tongue, etc., to create a complete sensory experience of the sight, sound, smell, touch, etc., of being in contact with and partially controlling a constructed but vivid world. Humans get many sensory clues telling them that their virtual realities are not real. Ems need see no such clues. Second, the cost to compute a workable virtual reality can be very low, compared with the cost to compute an em. Now it is true that the cost to compute a virtual environment depends greatly on the level of realistic detail required. Consider the cost to give simulated inputs to an em that it could not distinguish, even with careful examination, from a real physical environment. For many familiar physical environments, such a simulation may cost many times the cost of running the emulation brain itself. However, humans today are routinely comfortable and moderately productive interacting with video game environments that require vastly less computing power than human-speed brain emulations will require. Also, instead of sending very fine-grain low-level signals of very particular sights and sounds, it may become possible to send cheaper-to-compute higherlevel signals that em brains interpret as their having seen the lower-level signals. For example, instead of sending individual light pixels to the eye, which then translates that to lines and areas, one might just send those lines and areas to the appropriate emulated neurons. Ems may prefer virtual reality environments that are expensive to compute, relative to the cost of running the ems themselves. Even so, cheaply computed environments seem sufficient to functionally support the vast majority of em activities, in both work and leisure. On the job, there is a tradeoff regarding whether to pay more for a more realistic virtual environment that might add to worker productivity.

In order to use virtual reality as a sport analysis tool, we need to be sure that an immersed athlete reacts realistically in a virtual environment. This has been validated for a real handball goalkeeper facing a virtual thrower. However, we currently ignore which visual variables induce a realistic motor behavior of the immersed handball goalkeeper. In this study, we used virtual reality to dissociate the visual information related to the movements of the player from the visual information related to the trajectory of the ball. Thus, the aim is to evaluate the relative influence of these different visual information sources on the goalkeeper's motor behavior. We tested 10 handball goalkeepers who had to predict the final position of the virtual ball in the goal when facing the following: only the throwing action of the attacking player (TA condition), only the resulting ball trajectory (BA condition), and both the throwing action of the attacking player and the resulting ball trajectory (TB condition). Here we show that performance was better in the BA and TB conditions, but contrary to expectations, performance was substantially worse in the TA condition. A significant effect of ball landing zone does, however, suggest that the relative importance between visual information from the player and the ball depends on the targeted zone in the goal. In some cases, body-based cues embedded in the throwing actions may have a minor influence on the ball trajectory and vice versa. Kinematics analysis was then combined with these results to determine why such differences occur depending on the ball landing zone and consequently how it can clarify the role of different sources of visual information on the motor behavior of an athlete immersed in a virtual environment.

We have built the world's largest virtual reality (VR) theater for the Gyeongju World Culture EXPO 2000. The VR theater is characterized by a huge shared VR space with tightly coupled user inputs from 651 audience members in real time. The shared 3D virtual environment is augmenting the physical audience space in harmony. Large computer-generated passive stereo images on a huge cylindrical screen provide the sensation of visual immersion. The theater also provides 3D audio, vibration, and olfactory display as well as the keypads for each of the audience members to interactively control the virtual environment. This paper introduces the issues raised and addressed during the design of a versatile VR theater, the production process, and the presentation techniques using the versatile display and interaction capability of the future theater.

The need for diverse knowledge and skills in the work of a designer is a problem in vocational education, which mainly focuses on the artistic aspect of design. The aim of this article is to analyze the specifics of User Interface Design, its relation to User Experience Design, to determine the User Interface designer professional skills and how to acquire them. Research methods – theoretical: literature research; empirical – questionnaire. Exploring educational opportunities in Experience Design and User Interface Design demonstrates the need for Video game Interface study programs, particularly in the Latvian context. As the curriculum is traditionally designed for narrowly focused specialization, it would be appropriate to develop study modules for User Interface Design that include acquiring both graphics, game design and programming skills. The results of the video game developer survey demonstrate the role of practice in improving professional experience.

Educational Aims

The extension of technology in current society has encouraged teachers to introduce products based on VR and IVR in their classrooms, especially video games. In this paper the specific role of video games in cultural heritage and history teaching is analyzed. Moreover, the results of recent research on the application of video games in Secondary Education is discussed. The results advocate taking into account principles such as Civic Education, Historical Relevance, Engagement, Applicability and Multimodality (what has been called the CREAM Model) in the design of a video game. These principles are especially important if the video game aims to introduce archaeological and/or historical contents into the classroom. This model has been implemented in the design of the IVR video game Carthago Nova, which is discussed as an exemplar of how the proposed principles can be engaged. The educational sequence, in which the video game is contextualized, reinforces its educational aims.

Virtual reality (VR) is considered an important technological development to impact the tourism industry. Hotels are constantly attempting to overcome the challenges they face in the presentation of their facilities in the virtual environment. This research has made one of the first attempts to understand VR’s ability to influence tourism consumers’ attitudes and behavioral intentions during the prepurchase phase and postpurchase phase of their purchase journey across three hotel preview styles, namely, (1) VR immersive headsets, (2) 360° VR tour, and (3) a static image website. Through a lab-based experiment with 270-participants, study 1 outlined the positive role of VR on learning about the hotel and visit intentions. Through a questionnaire with 409 actual tourism consumers following a hotel stay, study 2 detailed that VR plays a significant role in managing tourism consumers’ expectations through providing an authentic experience and stimulating the development of detailed mental imagery prior to their visit.

Weight Map

In this paper, we propose a method to efficiently control the path of non-playable characters (NPC) in an interactive virtual environment such as a game or virtual reality (VR) by calculating a weight map and path similarity based on the user’s path. Our method automatically constructs a navigation mesh that provides a new route to the NPC by referring to the user’s trajectory. Our method finds more paths that users usually go through as time passes, and the number of users increases. Accordingly, the paths that NPCs can traverse automatically are updated adaptively to the virtual environment. In addition, NPC agents can move smartly by assigning high weights to the user’s preferred paths. We tested the usefulness of the proposed method through several example scenarios in an interactive environment such as a video game or VR, and this method can be easily applied to various types of navigation based on the interactive environment.
