Process Portfolio VR Pod Purpose The Evolution of VR I strongly feel that VR is the future of gaming, however, currently, the field is not very popular due to its mediocre immersion. Despite the fact that VR headsets have advanced far enough to provide viewers with proficient, visual, immersion, the kinetic aspect of immersion has not been very focused on. Although Omni Directional treadmills have already been made, none have been made efficient, nor immersive enough for wide-scale use. From this project, I hope to gain an expanded knowledge base of mechanical physics as well as effectively combine creativity with the critical analysis of mechanics. I hope to also improve my applied mathematical skills as this project will be quite math-heavy. Lastly, I hope to improve my research-capabilities seeing as this project heavily relies on research. In addition to this, I hope to apply practical information with researched information cohesively.
Overview Driving Question How can I use my passion for applied physics to create an omni-directional treadmill?
Project summary My long-term goal of this project is to produce a physical prototype of my product and create a company around that while my short-time goal is to produce a virtual prototype. For my project, I will not quite an

Creating shapes with measurement specifications 2. Separating and making new components 3. Assembling components through joints 4. Navigating and selecting materials 5.
