The Digital-Twin User Interface

A digital-twin interface binds a live or simulated model of a machine to interactive views so users can inspect, query, and reason about state.

What a twin interface must do

A digital twin is a computational model kept in correspondence with a real or planned system. Its interface has to let a user move between a spatial view of the machine, the data attached to each component, and the models that predict behavior. The interface is where the model becomes usable knowledge rather than a database.

Linked spatial and data views

The central pattern is coordinated linking: selecting a component in the 3D scene filters the plots, tables, and documents to that component, and vice versa. This turns navigation into inquiry. See Coordinated Views for the mechanics.

Levels of detail and access

A public build exposes overview geometry and vetted numbers; a private engineering build exposes full detail. The interface must enforce this split cleanly so that sensitive geometry never leaks into a public view. Rendering large geometry in a browser relies on WebGL and level-of-detail.

Honest state

Because the Kronos machines are simulated and not yet built, the twin interface labels every field as design or simulation output and never presents a modeled quantity as a measurement. Construction begins Q2 2027; until first hardware, the twin is a design instrument.

Interaction

Good twin interfaces reward exploration; see Interactive Exploration and 3D Navigation.
