What are the main challenges that cause AR/VR project delivery timelines to be underestimated?
The main challenges include: 1) The gap between proof-of-concept demos and production-ready systems, 2) Device-specific SDK quirks and performance optimization requirements to maintain steady frame rates, 3) Continuous calibration testing across different lighting conditions and physical spaces, 4) The 'last 10% problem' involving extensive polish, bug fixing, and UX tuning for natural immersion, and 5) Asset pipeline bottlenecks when 3D models move from designers to developers.
