01Overview

In 1965 Sutherland proposed the “Ultimate Display”: a virtual world one could enter and interact with. In 1968 he built the first head-mounted display, the Sword of Damocles, tracked mechanically. In the 1980s VPL’s DataGlove and Eyephone took VR commercial.

In 2012 the Oculus Rift crowdfunding campaign re-ignited consumer VR; in 2016 the HTC Vive and PSVR shipped; in 2023 Apple Vision Pro explored spatial computing with passthrough video and eye tracking. AR overlays virtual content on the real world, from Pokémon GO to industrial repair. The hard problems never change: latency, field of view, comfort — and what it is actually for.

03Core concepts

Immersion

How strongly the user feels present inside the world.

Head tracking

Capture head pose in real time to reduce motion sickness.

Spatial computing

Anchor digital content in real space.

04Hands-on

Do it once — it beats reading it ten times

Build a WebXR scene on your phone, then measure frame time and explain why latency causes nausea

05Self-check

Say it in your own words first, then open the answer. Whatever you cannot explain is what to review next.

Can you explain "Immersion"?

How strongly the user feels present inside the world.

Can you explain "Head tracking"?

Capture head pose in real time to reduce motion sickness.

Can you explain "Spatial computing"?

Anchor digital content in real space.

What problem did it solve, and why was there nothing better at the time?

Go back to the history section: how was this done before, and what did it cost?

If you had to build it today, how would you break it down?

Use the hands-on task above: write a plan of at most three steps before you start.
