Innovating at the Intersection of XR, AI & HCI
Building OpenSpatialAI — an intelligence layer that lets XR systems understand people, spaces, and intent in real time.
Welcome to my website!
I’m Varun Siddaraju, an XR + AI Researcher and Systems Thinker focused on shaping the future of human–computer interaction.
My work explores how immersive systems, intelligent agents, and spatial interfaces can be designed and evaluated to solve real-world problems.
I translate this research into applied prototypes, platforms, and collaborations across education and industry.
OpenSpatialAI is the platform through which my Harmony XR + AI research becomes deployable spatial intelligence.
Value Proposition
I design and translate human-centered XR and AI research into scalable systems—bridging experimentation, applied development, and real-world impact across academia, industry, and education.
Why this approach?
A single, integrated ecosystem spanning research, experimentation, application, and education.
Rather than treating research, product development, and education as separate efforts, I design them as a connected system—allowing ideas to move seamlessly from theory to real-world impact.
• Research-driven foundations, not trend-driven demos
• Continuous flow from experimentation to applied systems
• Education and community as force multipliers, not afterthoughts
Current Focus
What I’m actively working on
My focus evolves over time, but these are the areas I’m currently investing the most research, experimentation, and execution effort in.
• Advancing XR + AI research frameworks around human-centered, adaptive immersive systems
• Translating research into applied prototypes through VeeRuby and ecosystem collaborations
• Deepening long-term research direction while building sustainable research and education infrastructure
Featured In:
From esteemed institutions to global corporations, I’ve been featured in prominent magazines, felicitated, and recognized by leading tech companies.

My Innovation Ecosystem
How my research, labs, and ventures connect
My work operates through a connected ecosystem of research labs, innovation initiatives, and venture platforms—designed to explore, validate, and translate ideas at the intersection of XR, AI, and Human–Computer Interaction.
Research → Experimentation → Real-world Impact
Rather than isolated projects, this ecosystem allows me to move ideas fluidly—from deep research and experimental frameworks to real-world products, collaborations, and long-term ventures. Every initiative plays a distinct role, while reinforcing a unified vision of human-centered, future-ready technology.
Together, these ecosystems form the foundation of my research, innovation, and impact.
