digital signage GLOSSARY

Trigger

A Trigger in digital signage is any event that activates a signage action — a touch on an interactive widget, a sensor reading, a timer expiring, a data value crossing a threshold, an external API call, a QR scan, an NFC tap, a button press on Live Controller. Triggers are the input layer of AV orchestration: they transform signage from a scheduled channel into a responsive system.

In Livesignage, triggers are first-class concepts in the Flow engine. Operators define trigger-action chains visually in the Experience Designer: "when X happens, do Y, Z, and W". The full trigger catalogue includes timers, sensors (BLE, NFC, RFID, motion), touch widgets, data values, weather, external APIs, webhooks, and mobile conversions — all combinable into complex multi-condition scenarios.

Use Cases

Trigger-driven scenarios across industries:

- Retail and showrooms: presence triggers personalized product scenes.
- Museums: visitor proximity activates immersive narrative content.
- Smart city: weather alerts trigger network-wide public messaging.
- Industrial: machine telemetry triggers operator dashboards and alarms.
- Hospitality and events: time triggers transition day-parted content automatically.
