Biography
Ravi Kkumaar Sivasankar Venkata is a graduate student pursuing a Master of Science in Computer Science at the University of Massachusetts Lowell. His research focuses on Augmented Reality (AR), hand-tracking systems, gesture-based interaction, and real-time graphics optimization using Unity and Magic Leap 2. Ravi explores the integration of human-centered computing, AI-driven guidance systems, and immersive rehabilitation applications.
His work spans advanced AR/VR development, 27-joint hand tracking, virtual object manipulation, and motion-based physiotherapy training using spatial computing technologies. He has experience designing rehabilitation workflows, adaptive feedback algorithms, and AI-powered “Virtual-hand” demonstrations for guiding user movement with precision.
Before starting graduate studies, Ravi worked as an Azure Data Engineer Trainee and Full Stack Developer, building scalable data pipelines, cloud-based analytics solutions, and interactive web applications. He also creates educational VR content using Insta360 cameras and ThingLink, producing immersive lab tours across multiple engineering disciplines at UMass Lowell
