This project above is a beautiful showcase of the "Broadcast" action available in DISPL Designer. Using a custom template in one portable device such as iPhone/iPad, tablets or laptops, you can control the behaviour of neighboring devices in the same network, changing the digital signage content and stepping up your customer's experience!

Suggested applications:

• Sales representative personal device for giving interactive pitch for customers at high-end commercial environments;
• Alert systems for emergencies in crowded spaces such as shopping malls, stadiums, hospitals, events centers, etc;
• Interactive experiences in self-service sales stands, applied in digitally-augmented catalogues, interactive games, dynamic sales, DISPL product showcase, and more.
• Digital punchcard integration, generating automated forms everytime an employee checks-in for work, with date, time, professional picture and screenshot of the employee actually signing in.   

How it works

In a local network with two or more devices running DISPL Player, devices intercommunicate using the P2P synchorization feature, sharing visitor analytics informations, content data, and more. One of those informations shared is a 'Broadcast message", a simple string of text sent from one device to all others in the same local network that can be used as a trigger for several template actions, such as change scene, play next media gallery item in playlist, restart device.

Example

At Totem A, when clicking Product 1 button > send broadcast "product1". Screen B receives broadcast, on receive > change scene to "Product 1 video showcase". After media gallery end playlist, schenge scene back to "Generic".

Step-by-step

Broadcaster Template (for the device that broadcasts the string message)

1. Create a template for the Broadcaster Device, or edit the one you are currently working on.
2. Create an Interface Editor. One scene only.
3. Create a trigger for broadcast. For this example, we'll create button that, when pressed, broadcasts the corresponding text to all neighboring devices.
    
4. Select the button,open Actions tab, add action onClick > broadcast
5. Click the new action, and fill the text input with the broadcast string, "product1" in this example.
6. Repeat the last step for other buttons, such as "product2" and "product3".
7. Save the template and upload to platform
8. Create a campaign for the broadcaster device with the created template.

Receiver Template (for the device that receives the broadcast message and reacts)

1. Create a template for the Receiver Device, or edit the one you're currently working on.
2. Create a Generic Campaign scene, containing a simple Media Gallery. 
3. Create 3 new scenes for Products 1, 2 and 3. 
4. At the Generic Campaign, select the background, add 3 actions with onReceive > go to. These actions will change scenes upon receiving a specific broadcast message.
5. Link the actions to the respective scenes, and specify the broadcast messages meant to be received: "product1", "product2' and "product3".
   
6. Add one Media Gallery component for each product's scene
7. Select the background of each Product scene, Settings tab, set the duration and link to Generic Campaign. This will make the product ad last for 5 seconds then go back to wait for another Product input from the Broadcast device. 
   
8. Save the template, and upload to platform.
9. Create a campaign for the Receiver device with the created template.

Testing

• Open DISPL Player on both devices, and wait until the templates are loaded to the devices.
• Make sure the devices are on the same local network, and check if they can see each other on the CMS Device menu's P2P section.
• On Broadcaster device, click on "Product 1', and observe that the Receive device reacts to it.

• Test it for the other 2 products.
• (Advanced) - You may double-check the outgoing and incoming P2P broadcast messages at the Player console if you add the "p2pt" context.
