Using triggers, you can setup advanced conditions and actions for your digital signage playback.
Trigger setup is possible through the web interface, menu Settings
– Triggers
. It is possible to backup and restore triggers using XML configuration backup.
Setting up a trigger
The basic building block of each trigger is the control element. There can be multiple control elements defined, each one is evaluated separately. Each control element defines:
- Which event starts this trigger – screen was clicked, face detection was run, key was pressed or minute timer was run.
- What are the conditions for this trigger – for example position of the screen click, how many faces were detected, what time it is and more. Conditions can be combined using logic predicates “and”, “or” and “not”.
- What action should be executed if the conditions are satisfied – for example change playlist or screen layout, display particular file, pause or resume playback etc.
You can add building blocks from the left menu to the workspace using drag & drop. Make sure that the building block is not whited out after placing it in the workspace, as it might indicate the output type of the block doesn’t fit the input type of the other block.
After the triggers are saved, the actions will be automatically executed if the event occurs and the conditions are satisfied.
Examples
If screen was clicked in the top 10% and it is Monday, change the current screen layout to “Special Monday layout”
If more than 10 faces were detected on average in the last 3 frames, display file “welcome.jpg” in zone “Left side” for 15 seconds
