Try v2: two views with camera-based head tracking ↗
Compare the same brooch in motion, side by side. These are depth illusions on your screen; a true light-field display needs additional optics.
Camera frames stay on your device. Tap Start head tracking to request camera access.
Tracking off · Position not calibratedLoading the original brooch (18 MB). The controls and research are ready below.
The jewel stays still as the view shifts behind a fixed window. Drag here or move the shared slider.
No accessory neededStart head tracking above to use your camera.Automatic motion simulates a viewer moving sideways.
The view stays fixed while studio lighting moves. This material cue is ordinary 3D shading, not a captured light field.
No accessory neededPhone tilt or the slider controls the lighting angle.
A parallel stereo pair. A compatible stereoscopic viewer separates the images; on a bare phone you see two views.
Viewer or red/cyan glasses neededFour copies reflect from a clear pyramid. The reflected images appear inside it; this is Pepper’s ghost, not volumetric holography.
Clear reflection pyramid neededOn an iPhone, open this page in Safari and tap the image to launch Apple AR Quick Look. You still focus on the phone’s screen.

“Light field mimicry” is a useful informal description, not one established research method. A normal iPhone can change a rendered view with motion, shade materials, show stereo images, or drive an optical attachment. Software alone does not add independent focus planes to its screen.
Hoffman, Girshick, Akeley & Banks. Experiments on conflicting focus and binocular depth cues. This does not establish a “zero fatigue” score for this demo.
REVIEW · 2016 · PUBMEDGregory Kramida. Reviews optical and computational approaches for head-mounted displays; a software effect on a phone is not equivalent to their hardware.
MOBILE INTERACTION · 2011 · PAPER PDFFrancone & Nigay. Camera-based head tracking changes mobile-device perspective. Our moving-window demo illustrates that cue; tilt is not head tracking.
DISPLAY HARDWARE · SIGGRAPH 2015Huang, Chen & Wetzstein. Stacked liquid-crystal panels and viewing optics support focus cues. Requires a physical display system beyond an ordinary phone.
PHONE OPTICS · SIGGRAPH 2010 · PAPER PDFPamplona, Mohan, Oliveira & Raskar. A near-eye optical attachment for refractive assessment, not a free-floating hologram application.
DISPLAY HARDWARE · SIGGRAPH 2011Multiple attenuating layers reproduce directional light. This is an example of the added hardware required for an actual light-field display.
PubMed and PubMed Central index or host research; they do not certify this demo. No eye position in physical units, accommodation, fatigue, or motion-to-photon latency is measured here. The frame counter reports browser animation intervals only. NeRF and Gaussian splatting are scene representations, not upgrades to a screen’s optical capabilities.
