iCOMPEL Digital Signage - User Guide (V8.1.1)

4.2 Using Interactivity

You can configure the iCOMPEL to respond to inputs from an external source. These external inputs are known as Events

and they may be caused by:

someone pressing or releasing a defined area on a USB Touch Screens

someone passing a detector or stepping on a pressure mat that generates a General Purpose Input/Output (GPIO) signal

(received through an RS-232 port)

someone pressing a button on a Remote Keypad (Infra-red controller)

The way the iCOMPEL responds may include:

executing a Change Layout command

executing an Advance to command

These responses are known as Actions , and they may occur immediately, or after a defined time delay (timeout) period.

Together, the combination of an input event and an action in response to it is known as an interaction.

Events

You can specify actions for a Layout or a Playlist when any of the following events take place:

when the Touch Screen is Pressed or Released.

when a Positive or Negative voltage is received as a GPIO signal.

when a Programmable Button (A, B, C, D) is pressed on a Remote Keypad.

You can also specify time-delayed (Timeout) actions for the following Timeout events:

a specified number of seconds after the last Touch or GPIO event was received by the Layout or Playlist.

if a Touch or GPIO Input event has not occurred within a specified number of seconds after the Layout started playing.

Actions

The following Actions are common to all Events:

Change to specified Layout when the event (or Timeout) is received.

Advance to Rendezvous Point when event (or Timeout) is received.

Pass Event to other Zones or the Layout as required. The event is ignored by this Zone or Layout.

Additionally Playlist Touch and GPIO Interactions can have the action:

No Action specifies that the event should not be passed to other Zones.

Playlist Touch Interactions can have the action:

Pass to Web Page. If the current Zone supports HTML, then Touch Events can be passed directly to the currently

shown Web Page. If there is no web page showing, the Event is treated as if the selection is No Action.

Layout and Playlist Interaction

You can specify interaction behavior for both the Layout and the Playlist for different purposes.

Interactions defined within the Playlist have the following properties:

they are processed if the currently playing item in the Playlist is touched.

the last encountered interaction item is active. This allows complex behavior to be executed by defining multiple

interaction items in the same Playlist.

Layout interactions have the following properties:

they are applied if no Playlist interaction item is processed, which means that Layout interactions can be considered

default interactions.
