4.2 Using Interactivity

You can configure the iCOMPEL to respond to inputs from an external source. External inputs are known as Events and
they may be caused by:
Someone pressing or releasing a defined area on a USB touch screen.
Someone passing a detector or stepping on a pressure mat that generates a general purpose input/output (GPIO) signal
(received through the iCOMPEL unit's RS-232 port).
Someone pressing a button on a remote keypad (infra-red controller).
The way you configure the iCOMPEL to respond may include:
Executing a Change Layout command.
Executing an Advance To command.
Those responses are known as Actions and you can configure the iCOMPEL to take them immediately or after a timeout.
Together, the combination of an event and an action is known as an Interaction.
For all events (or timeouts), you can have the iCOMPEL take one of these actions:
Change to a specified layout.
Advance to a rendezvous point.
Ignore the event for this zone or layout and pass it to another zone or layout.
Additionally, for touch and GPIO events, you can have the iCOMPEL take one of these actions:
Touch and GPIO events – Take no action.
Touch event – Pass to a web page. If the zone supports HTML, the iCOMPEL can pass a touch event to the currently
showing web page. If there is no web page, the iCOMPEL takes no action.
Playlist and Layout Interaction:
To provide detailed control, you can specify behavior that differs at the playlist and at the layout level:
Playlist:
o Process the interaction if someone touches the currently playing item.
o Keep the interaction process active awaiting other events. You can implement complex behavior by defining multiple
interaction actions in the same playlist.
Layout:
o Process the interaction if there is no playlist action (that is, the layout action is a default).
o Process the interaction if someone touches anywhere on the screen.
You will find it easier to review layout interaction behavior because the iCOMPEL displays all layout components at once.
To configure touch actions for a playlist, you must either:
