Location based content (POI triggering)

Overview

In this tutorial I will be going through how to use a Garmin GPS device, DISE Parser and some scheduling to create a location aware digital signage presentation, for use in a moving train, for example.

Files used in this tutorial

Download: File:POI.zip

Setup

Follow the instructions given in DISE Parser Modifiers to setup your GPS device.
Extract the attached files in "C:\DISEContent\Content\GPS".
In DISE Parser, File > Import the "C:\DISEContent\Content\GPS\poi_simulate.dpmodifiers" file.
Open up and take a look at the file "C:\DISEContent\Content\GPS\poi.xml". This file contains Points of Interest, a sample POI equals to the DISE HQ in Karlstad, Sweden. The id "DISEHQ" is what Parser will send on the network.

(You can later copy this POI and give your new POI ids and positions (latitude and longitude), but for now leave it as is).

Initial testing

Open up DISE Replay.
Go into Replay's settings and the Communication tab.
Check the boxes Enable Remote Control of this player and Enable multicast communication.
Make sure IP is set to "224.1.1.100" and Port is "4000".
Click Ok.
Select Information > Remote Control View in the top menu. You will now be able to see incoming messages on the multicast address (none yet).
In DISE Parser, click Test to start the process.
Open up the file "C:\DISEContent\Content\GPS\simulate.xsl" in a text editor. Look for the following line:

Example:

<xsl:variable name="simulated_distance" select="51"/>

Change the 51 to 50. Save the file.
Notice that in Replay in the Remote Control View dialog, when the distance changes to be less or equal to 50, its id will be sent and displayed as: "<timestamp>|Garmin|DISEHQ", once every second.

Create and schedule content

DISE Composer

I create two DISE Movies, one that will be play by default and one that will be triggered.
In the first DISE Movie, background.disemovie, I insert a simple image.

DISE Bridge

Create a new destination.
In the "Main" channel, drag and drop the file background.disemovie.
Create a new channel, and call it "POI".
We want this channel to appear when "DISEHQ" is on the multicast channel, indicating that the point of interest "DISEHQ" is less than 50 meters away.
Select the channel POI, put some content for triggered play, the file disehq.disemovie.
Right click the POI channel and select Schedule.
In the Remote Control tab, check Remote Control and type Garmin|DISEHQ in the Trigger field.

200px

This informs the channel that it should listen for the trigger "DISEHQ" with the identity "Garmin".

In the Valid field enter 10. It is how long after the POI has been passed the channel should be visible.
Send out the destination.

DISE Replay

Point DISE Replay to the display scheme of the destination just sent out.
Verify that the communication settings are ok. (See #Initial testing above)
Play the content.

Test

Before deployment

To use the real device, in DISE Parser, File > Import and select the file "C:\DISEContent\Content\GPS\poi.dpmodifiers".
Add points of interests in the poi.xml file.
Tweak the settings for the accuracy in the near.xsl file.

Look for the following line:
