# Motion Tracker

The motion tracker is included as a compact example of an interface prop: it
turns invisible movement into readable pressure. In PathMX, that makes it a good
node for linking sound, blocking, suspense, and reader attention.

- Setup scene: [Scene 2 - Priority Message](../alien.screenplay.md#scene-2-priority-message)
- Payoff scene: [Scene 5 - Search Pattern](../alien.screenplay.md#scene-5-search-pattern)
- Related character: [Ellen Ripley](../characters/ripley.character.md)
- Related location: [USCSS Nostromo](../locations/nostromo.location.md)

## PathMX Role

Object nodes make recurring props inspectable without interrupting scene rhythm.
