Qualcomm Reveals Key Challenges for Next-Gen XR Glasses
The Future of Extended Reality (XR) Hinges on Industry Collaboration
Qualcomm, a leader in mobile chipset technology, is at the forefront of developing hardware for extended reality (XR) — an umbrella term encompassing virtual reality (VR), augmented reality (AR), and mixed reality (MR). At the Augmented World Expo (AWE), Tim Leland, VP of Product Management at Qualcomm, outlined the critical hurdles the industry must overcome to make XR glasses mainstream.
The Current State of XR: Progress and Pain Points
Qualcomm is actively supporting XR development through:
- Snapdragon 835 VR HMD dev kits for developers
- Partnerships with companies like ODG, Leap Motion, and SMI
- Advancements in 6DoF (six degrees of freedom) tracking and eye-tracking algorithms
However, Leland emphasized that XR still faces significant technical challenges:
- Visual Realism: AR objects often appear fake due to improper lighting and shadow rendering.
- Power Consumption: High-performance processing drains battery life quickly.
- Form Factor: Future XR glasses must be lightweight and socially acceptable.
- Latency: Seamless AR/VR requires ultra-low motion-to-photon latency.
- Content Ecosystem: More engaging applications are needed for mass adoption.
Key Technical Hurdles
1. Lighting and Shadows
- Without accurate lighting, virtual objects fail to blend naturally into real-world environments.
- Solving this requires advanced visual processing, increasing power demands.
2. Battery Life and Performance
- High-fidelity XR experiences demand significant computational power.
- Foveated rendering (focusing processing on the user’s gaze point) can help optimize efficiency.
3. Wireless and Self-Contained Design
- Future XR glasses must be cable-free and fanless for consumer appeal.
- 5G connectivity will enable low-latency streaming for video content.
The Road Ahead: A 30-Year Evolution
Leland compared XR’s development to the smartphone revolution:
- Current Phase (1990s Analogy): Early adoption, refining hardware and software.
- 2020s and Beyond: Expected surge in consumer adoption as devices improve.
- Mass Market Potential: Hundreds of millions of units annually by the 2030s.
Industry Collaboration is Critical
Leland stressed that no single company can solve XR’s challenges alone. Key areas requiring industry-wide cooperation include:
- Standardizing foveated rendering for better power efficiency
- Improving hand and eye-tracking algorithms
- Developing low-latency 5G streaming solutions
Gaming and Future Applications
- AR Gaming: Could revive classic board games in digital form.
- VR Gaming: Major publishers are optimizing titles for mobile VR.
- Professional Use Cases: Firefighters, engineers, and first responders may adopt specialized XR glasses.
The 5G Factor
5G will revolutionize XR by enabling:
- 8K 120fps streaming with ultra-low latency
- Free-viewpoint video (allowing users to “walk around” in recorded scenes)
- Cloud-assisted rendering to reduce on-device processing
When Will XR Feel “Real”?
Leland predicts that by the mid-2030s, some XR experiences may become indistinguishable from reality. However, ethical concerns, such as deepfake-like manipulations in AR, will also emerge.
Final Thoughts
The XR industry is at a pivotal moment. While challenges remain, collaborative innovation between chipmakers, developers, and content creators will drive the next wave of immersive computing. As Qualcomm and its partners push forward, the dream of sleek, high-performance XR glasses is inching closer to reality.
