Passthrough

Also known as:Video passthroughVideo see-through

Video passthrough uses cameras on a headset to show the physical surroundings on its displays, allowing digital content to be combined with that camera view.

You see a camera view of the room

In a video-passthrough headset, the outside world is captured and displayed electronically. This differs from optical see-through glasses, where light from the real world passes through the optics to the eyes.

A dashed rectangle marks the display area, with portions of two artworks extending outside it.
The visible window can crop content that extends beyond the display field of view.

Why the distinction matters for art

Camera exposure, colour reproduction, resolution, distortion and delay can affect how a physical artwork appears. A display specification alone does not tell you how faithfully a painting will look through the complete camera-and-display system.

A curator's practical check

Try the actual artwork under exhibition lighting. Check small labels, dark passages, bright highlights and the comfort of moving between the physical and digital elements.

Passthrough is not room understanding

Showing the room does not automatically provide accurate depth, persistent anchors or recognition of artworks. Those are separate capabilities. It also does not guarantee that a browser-based Painta experience is supported by that headset.
