Ball Wall:
Creating Bilaterial Racket-Sport Games in VR
Ball Wall was the capstone project of my Electrical Engineering degree. For the project, I blended VR hardware knowledge with software development in Unity to create a bilateral racket-sport game. I presented a live demo of the game to my peers and professors with a poster explaining my design choices.
Here, I share the poster and a video of the game from the user's perspective. The central figure in my poster (seen in the “New Technique” section) featured a flow diagram describing how ball collisions, scoring calculations, and VR physics integrated. I used arrows and color-coded blocks to illustrate the logic of detecting left/right racket hits, awarding points, and applying bounciness or gravity multipliers. This combination of text callouts and minimal stylized graphics helped viewers immediately grasp how both arms were involved in the gameplay. In the VR environment screenshots, I showcased the dual-racket perspective (left and right controllers rendered as tennis rackets) and the scoreboard's real-time updates. Those visuals captured both the technical side (realistic physics and collisions) and the user-centric side (a timer, scoring mechanics) that keep the game engaging. This synergy of short, labelled annotations and a real-time gameplay photo gave the audience a quick sense of how I achieved realistic physics simulations and full-body engagement in the game (Unity's physics engine + custom-coded scoring logic).
Technical Report
Along with the live demo, I also wrote a technical report to document the design process and the game mechanics. Crafting the written report in an academic style also showed me how crucial it is to document design decisions, cite relevant VR research, and present user-testing insights in a succinct but rigorous manner. Building on this experience, I plan to further develop my ability to explain how new prototypes and algorithms function in my research.
Furthermore, I learned the importance of effective education of advanced engineering concepts to students, inspiring me to create educational resources that make complex topics accessible and engaging.
