Motion capture using cost-effective sensing technology is challenging and the huge success of Microsoft Kinect has been attracting researchers to uncover the potential of using this technology into computer vision applications. In this thesis, an upper-body motion analysis in a home-based system for stroke rehabilitation using novel RGB-D camera - Kinect is presented. We address this problem by first conducting a systematic analysis of the usability of Kinect for motion analysis in stroke rehabilitation. Then a hybrid upper body tracking approach is proposed which combines off-the-shelf skeleton tracking with a novel depth-fused mean shift tracking method. We proposed several kinematic features reliably extracted from the proposed inexpensive and portable motion capture system and classifiers that correlate torso movement to clinical measures of unimpaired and impaired. Experiment results show that the proposed sensing and analysis works reliably on measuring torso movement quality and is promising for end-point tracking. The system is currently being deployed for large-scale evaluations.

Medical students acquire and enhance their clinical skills using various available techniques and resources. As the health care profession has move towards team-based practice, students and trainees need to practice team-based procedures that involve timely management of clinical tasks and adequate communication with other members of the team. Such team-based procedures include surgical and clinical procedures, some of which are protocol-driven. Cost and time required for individual team-based training sessions, along with other factors, contribute to making the training complex and challenging. A great deal of research has been done on medically-focused collaborative virtual reality (VR)-based training for protocol-driven procedures as a cost-effective as well as time-efficient solution. Most VR-based simulators focus on training of individual personnel. The ones which focus on providing team training provide an interactive simulation for only a few scenarios in a collaborative virtual environment (CVE). These simulators are suited for didactic training for cognitive skills development. The training sessions in the simulators require the physical presence of mentors. The problem with this kind of system is that the mentor must be present at the training location (either physically or virtually) to evaluate the performance of the team (or an individual). Another issue is that there is no efficient methodology that exists to provide feedback to the trainees during the training session itself (formative feedback). Furthermore, they lack the ability to provide training in acquisition or improvement of psychomotor skills for the tasks that require force or touch feedback such as cardiopulmonary resuscitation (CPR). To find a potential solution to overcome some of these concerns, a novel training system was designed and developed that utilizes the integration of sensors into a CVE for time-critical medical procedures. The system allows the participants to simultaneously access the CVE and receive training from geographically diverse locations. The system is also able to provide real-time feedback and is also able to store important data during each training/testing session. Finally, this study also presents a generalizable collaborative team-training system that can be used across various team-based procedures in medical as well as non-medical domains.

This study was undertaken to ascertain to what degree, if any, virtual reality training was superior to monitor based training. By analyzing the results in a 2x3 ANOVA it was found that little difference in training resulted from using virtual reality or monitor interaction to facilitate training. The data did suggest that training involving rich textured environments might be more beneficial under virtual reality conditions, however nothing significant was found in the analysis. It might be possible that significance could be obtained by comparing a virtual reality set-up with higher fidelity to a monitor trial.

The purpose of the Oculus Exercise research project we conducted was to find a way to entice individuals to attend a gym more often and for longer periods of time. We have found that many activities are being augmented by the increasingly popular virtual reality technology, and within that space "gamifying" the activity seems to attract more users. Given the idea of making activities more entertaining to users through "gamification", we decided to incorporate virtual reality, using the Oculus Rift, to immerse users within a simulated environment to potentially drive the factors previously identified in respect to gym utilization. To start, we surveyed potential users to gauge potential interest in virtual reality and its usage in physical exercise. Based on the initial responses, we saw that there was a definite interest in "gamifying" physical exercises using virtual reality, and proceeded to design a prototype using Unreal Engine 4 -- which is an engine for creating high quality video games with support for virtual reality -- to experiment how it would affect a standard workout routine. After considering several options, we decided to move forward with designing our prototype to augment a spin machine with virtual reality due to its common usage within a gym, and the consistent cardiovascular exercise it entails, as well as the safety intrinsic to it being a mostly stationary device. By analyzing the results of a survey after experimenting upon a user test group, we can begin to correlate the benefits and the drawbacks of using virtual reality in physical exercise, and the feasibility of doing so.

The foundations of legacy media, especially the news media, are not as strong as they once were. A digital revolution has changed the operation models for and journalistic organizations are trying to find their place in the new market. This project is intended to analyze the effects of new/emerging technologies on the journalism industry. Five different categories of technology will be explored. They are as follows: the semantic web, automation software, data analysis and aggregators, virtual reality and drone journalism. The potential of these technologies will be broken up according to four guidelines, ethical implications, effects on the reportorial process, business impacts and changes to the consumer experience. Upon my examination, it is apparent that no single technology will offer the journalism industry the remedy it has been searching for. Some combination of emerging technologies however, may form the basis for the next generation of news. Findings are presented on a website that features video, visuals, linked content, and original graphics. Website found at http://www.explorenewstech.com/

This paper will explore what makes ‘good’ virtual reality, that is, what constitutes the virtual reality threshold. It will explain what this has to do with the temporary death of virtual reality, and argue that that threshold has now been crossed and true virtual reality is now possible, as evidenced by the current wave of virtual reality catalyzed by the Oculus Rift. The Rift will be used as a case study for examining specific aspects of the virtual reality threshold.

Motion simulators are a common feature in everything from high end science museums to amusement parks, allowing a full ride experience on a small footprint and at a comparatively low cost relative to full size rides. The rapidly advancing field of virtual reality provides a potential increase in this desire for motion simulators, by combing virtual reality with motion simulation, total immersions can be created that is competitive with theme parks. While there exists a small number of commercially available consumer motion simulators, these tend to not have a wide enough range of motion to provide flexibility for use cases. This report is the documentation of an attempt to create a low cost consumer grade motion simulator prototype to determine to what extent an adequate motion simulation experience can be created in the home environment. This design made use of a two degree of freedom platform mounted on a universal joint as a trade off between flexibility of use and affordability of the end product. Ultimately, although the design and motor selection was sound, structural issues prevented the design from being capable of withstanding the necessary forces. However, as a prototype, important lessons were learned that could apply to a better-constructed second generation design. The results definitely show that motion simulators will, in the near future, become feasible for in-home amusement park recreation, at least for some amusement park rides.

Dale and Edna is a hybrid animated film and videogame experienced in virtual reality with dual storylines that increases in potential meanings through player interaction. Developed and played within Unreal Engine 4 using the HTC Vive, Oculus, or PlayStation VR, Dale and Edna allows for players to passively enjoy the film element of the project or partake in the active videogame portion. Exploration of the virtual story world yields more information about that world, which may or may not alter the audience’s perception of the world. The film portion of the project is a static narrative with a plot that cannot be altered by players within the virtual world. In the static plot, the characters Dale and Edna discover and subsequently combat an alien invasion that appears to have the objective of demolishing Dale’s prize pumpkin. However, the aliens in the film plot are merely projections created by AR headsets that are reflecting Jimmy’s gameplay on his tablet. The audience is thus invited to question their perception of reality through combined use of VR and AR. The game element is a dynamic narrative scaffold that does not unfold as a traditional narrative might. Instead, what a player observes and interacts with within the sandbox level will determine the meaning those players come away from this project with. Both elements of the project feature modular code construction so developers can return to both the film and game portions of the project and make additions. This paper will analyze the chronological development of the project along with the guiding philosophy that was revealed in the result.

Virtual reality gives users the opportunity to immerse themselves in an accurately
simulated computer-generated environment. These environments are accurately simulated in that they provide the appearance of- and allow users to interact with- the simulated environment. Using head-mounted displays, controllers, and auditory feedback, virtual reality provides a convincing simulation of interactable virtual worlds (Wikipedia, “Virtual reality”). The many worlds of virtual reality are often expansive, colorful, and detailed. However, there is one great flaw among them- an emotion evoked in many users through the exploration of such worlds-loneliness.
The content in these worlds is impressive, immersive, and entertaining. Without other people to share in these experiences, however, one can find themselves lonely. Users discover a feeling that no matter how many objects and colors surround them in countless virtual worlds, every world feels empty. As humans are social beings by nature, they feel lost without a sense of human connection and human interaction. Multiplayer experiences offer this missing element into the immersion of virtual reality worlds. Multiplayer offers users the opportunity to interact with other live people in a virtual simulation, which creates lasting memories and deeper, more meaningful immersion.
