Glasses-free 3D tried to take over living rooms a decade ago—and flopped. So what changed? In this episode of Today in Tech, host Keith Shaw sits down with David Fattal, founder and CTO of Leia Inc., to break down why 3D TVs collapsed (hype, lack of content, and imperfect tech) and why the next wave of glasses-free 3D could be different.

We dig into the breakthroughs powering this comeback: switchable 2D/3D displays, AI-driven head tracking that preserves sharp resolution, and real-time 2D-to-3D conversion that can unlock everything from live sports to teleconferencing. Fattal also explains what “the consumer bar” means, why monitors and laptops may lead the adoption, and how phones could become the key to building the massive 3D data sets needed for true spatial AI.

Watch to learn what’s real, what’s hype, and the biggest misconceptions that still hold glasses-free 3D back—plus a realistic timeline for when this tech could show up in mainstream devices.

Why glasses-free 3D failed, and why it might finally work now
