CAP Live Chat Wall: Connecting QR Access, Moderation and LED Screens

A venue screen can do more than repeat a promotional loop. It can also give the audience a shared place to participate. CAP Live Chat Wall connects a room accessed from a phone with messages presented on an LED display, while keeping moderation and screen controls in the operator’s workflow.

Start with the audience journey

The audience journey begins with a QR code and a room entry page. Guests choose a nickname and avatar before composing a message. Reactions and photo submissions provide additional ways to participate. This separation matters: the phone interface should stay easy to use while the public display remains readable from a distance.

Participation needs a review process. The application provides approval, rejection and highlight actions, alongside moderation settings. These controls give the venue a way to manage content before or during its appearance on the shared screen. A moderation policy still needs an assigned operator and clear rules for the event.

Design for the LED display

The LED presentation has its own requirements. CAP Live Chat Wall includes landscape, chat-wall and other layout options, configurable dimensions and screen presentation settings. A design that works on a phone cannot simply be enlarged and assumed to work across a venue. Text size, message density and QR placement need to suit the actual screen and audience positions.

Screen controls cover more than displaying the latest messages. The application contains standby, blackout, announcement, countdown and highlight functions, with polling and winner features available within its room tools. Choosing which elements to show is part of preparing a session, so a display does not become crowded with every feature at once.

Keep operations and history connected

Daily audience periods and historical records serve different purposes. A new operating period can change which content is active without requiring deletion of the previous conversation history. The application also provides room reports and CSV exports. For venue operations, the useful question is what should remain visible now and what should remain available for later review.

The screenshots in this article are rendered from the actual application templates using sample messages. Guest names are fictional, and the documentation QR links to the portfolio rather than an active audience room. The images explain the product interface; they do not represent a live customer conversation or a measured increase in engagement.

Plan the complete workflow

For a similar project, begin with the audience entry journey, the moderation responsibility and the physical display. Then define the room’s operating period, reporting needs and visual priorities. The CAP Live Chat Wall portfolio shows how these parts can be brought together as a venue application that supports the operator as well as the audience.
