Case Study: Automation Creates Immersive and Interactive Experiences in Escape Rooms

Sound logic

A critical aspect of the immersive experience is sound effects. Sound is used in a variety of different ways to enhance gameplay. Background sounds amplify the theme, and in some cases sound is used to deliver clues.

Specialized electronic audio boards are used to play sound files. Most commercially available boards are typically limited to a single audio port, or jack. However, to manage the many sound effects used throughout the game, the client had developed a custom sound box comprised of printed circuit boards (PCBs) fitted with numerous stereo and mono audio ports. This custom sound box configuration with multiple audio ports allows various sound effects to be played—concurrently if needed—in different rooms and locations throughout the game based on specific triggers from the PLC. The sound effects used during the game are saved as mono WAV files and stored onboard the PCB via an SD card.

The sound box (Figure 4) receives commands from the PLC using serial communication. Serial communication is an efficient way to manage the many sound effects, reducing the number of wires and I/O that would otherwise be required by discrete signals. As the gameplay progresses, the PLC determines which sounds to play. A message is sent from the PLC to the sound board using the built-in RS-232 communication protocol to trigger a specific audio file. Sounds can be played a single-time or looped, depending on the desired effect and the status of the inputs at various points during the game.

Behind the scenes

Due to the lack of on-site support should a technical need arise, as well as the desire to franchise the game to multiple locations, and AutomationDirect StrideLinx VPN router was also included in the system architecture. The VPN router allows remote access via a secure wired, wireless, or cellular connection through a cloud-based server network, and it is specifically compatible with industrial devices such as PLCs and HMIs. With the VPN router, connected devices can be accessed through a secure VPN connection as if you were directly connected on-site.

The VPN router was instrumental during the implementation phase of the project. Remarkably, the entire programming and commissioning process was completed remotely. Utilizing remote VPN access and the C-more mobile app, Schulman did not have to travel to the escape room. This approach resulted in substantial time and cost savings for both the SI and entertainment company.

With a solid commitment to providing intuitive, quality products and exceptional technical support, AutomationDirect was an ideal partner for this unconventional application. Similarly, Schulman’s client was impressed by the resulting system performance, and the training and support provided so they could develop their in-house ability to maintain the system. The products and teamwork proved to be a winning choice for this customer to play the long game.
