Spatial computing describes computing that uses position, movement and relationships in three-dimensional space as part of how people interact with digital content.
Space becomes part of the interface
Instead of interacting only with a flat page, a person may place, approach, look around or manipulate digital objects in a spatial setting. Cameras, tracking systems, displays and input methods can contribute to this behaviour.
An art example
An interpretation might appear beside a sculpture and change as the visitor moves around it. The position of the visitor and the object helps shape what is presented.
The term is broader than a headset
Phones, tablets, headsets and other systems can support spatial interactions. The phrase is also used differently by different vendors, so it does not identify one standard feature set.
Describe the useful capability
For a Painta project, explain what the visitor can actually do: follow an animation on a painting, inspect a digital object or move between works in a collection. Do not assume that the spatial-computing label implies shared anchors, automatic room mapping or compatibility with every XR device.
