What Is an Interactive Event Wall? (Clear Definition, Setup & Use Cases)
An interactive event wall is a real-time digital display where attendees submit photos, messages, and reactions via QR code or link, and content appears instantly on a shared screen. In 2026, the best interactive event walls require no app download, include AI content moderation, and support multiple display modes (slideshow, feed, grid). Here's everything you need to know about setup, pricing, and use cases.
TL;DR — What is an interactive event wall?
An interactive event wall is a real-time display system where event attendees scan a QR code to submit messages, questions, photos, and reactions that appear instantly on a shared screen. Unlike social media walls (which aggregate hashtags from Instagram/X) or polling apps (which show multiple-choice votes), interactive walls enable open-ended participation without requiring attendees to have social media accounts or download apps. Common use cases include corporate town halls, conference Q&A sessions, university orientations, and trade show booths.
Clear definition
An interactive event wall (also called a QR wall, live wall, or audience engagement wall) is a digital display that shows user-generated content from event attendees in real-time. Attendees participate by:
- Scanning a QR code with their phone camera (no app download required)
- Submitting text messages, questions, photos, or emoji reactions
- Watching their submission appear on the event display within seconds
The wall creates a feedback loop: as people see others contributing, they feel encouraged to participate, compounding engagement throughout the event.
Key features
- Zero-friction participation: Scan QR code → type message → submit. Takes 3-5 seconds.
- Real-time display: Submissions appear instantly on projected screens or monitors.
- Anonymous or named: Attendees can choose to display their name or submit anonymously.
- Moderation controls: AI filtering, manual approval, freeze display, or profanity blocking.
- Export & analytics: Download all submissions after the event for analysis and follow-up.

5-minute setup checklist
Setting up an interactive event wall takes less time than ordering coffee. Here's the complete process:
Step-by-step setup (5 minutes)
- 1. Create your event (60 seconds) — Sign in, click "Create Event," give it a name (e.g., "Q4 All-Hands" or "TechCon 2025"), and optionally add a prompt like "Ask questions for leadership" or "Share one win from this week."
- 2. Display the QR code (30 seconds) — Your event dashboard shows a QR code. Add it to your presentation slides, print it on signage, or project it on hallway monitors. Attendees scan it with their phone camera — no app download needed.
- 3. Open the display link (30 seconds) — Copy the display URL from your dashboard and open it on the device connected to your projector or TV. This is the screen everyone will see submissions on.
- 4. Configure moderation (2 minutes, optional) — Turn on AI moderation (Professional tier), enable manual approval mode, or just use the freeze button if something unexpected appears. Most events run fine with default settings.
- 5. Test it (60 seconds) — Scan the QR code yourself, submit a test message ("Testing 1-2-3"), and watch it appear on the display. You're live.
The 3-second participation flow (attendee perspective)
- Scan: Point phone camera at QR code (works like scanning a menu at a restaurant)
- Submit: Type message or upload photo, hit "Send"
- Appear: Watch it pop up on the big screen in 1-2 seconds

Risks & safeguards
Open submission systems carry inherent risks. Here's how interactive walls mitigate them:
Risk: profanity or inappropriate content
Safeguard (Free/Premium): Freeze button lets presenters instantly stop new submissions from appearing on screen. Submissions continue in the background but don't display until unfrozen.
Safeguard (Professional): AI moderation automatically filters submissions by professionalism level (1-5 scale). Only content rated 1-2 (professional, appropriate) appears on the wall. Happens invisibly and instantly.
Risk: offensive images
Safeguard (all tiers): Image uploads can be disabled entirely. When enabled, moderators can delete submissions from the dashboard. Images are processed and optimized (no executable files accepted).
Risk: spam or floods
Safeguard (all tiers): Rate limiting prevents one person from submitting 50 messages in 10 seconds. Display can be set to show most recent submissions only (auto-archives older content).
Risk: privacy concerns
Safeguard (all tiers): Anonymous mode lets attendees submit without names. Clear consent: "Your message will appear on the public display" shown before submission. No personal data collected beyond what attendees choose to share.
Real-world use cases
Corporate town halls
Anonymous Q&A during leadership presentations. Employees submit questions throughout the talk; moderator surfaces top questions for live answers.
Typical participation: 35-65% of attendees submit at least one question.
Conference sessions
Continuous Q&A during panels. Attendees submit questions as they think of them instead of waiting for "any questions?" at the end.
Typical participation: 50+ questions for a 200-person session (vs. 3-5 with raised hands).
University orientations
Icebreaker prompts like "Your major + one thing you're excited about." Students see others with similar interests and connect organically.
Typical participation: 40%+ of freshmen post in first 15 minutes.
Trade show booths
"Share your biggest [industry challenge]" prompt. Visible activity attracts foot traffic; submitted challenges pre-qualify leads for booth staff.
Typical impact: 3x longer dwell time (90 seconds → 4.5 minutes).
Frequently asked questions
What is an interactive event wall?
An interactive event wall is a real-time display where event attendees scan a QR code to submit messages, questions, photos, or reactions that appear instantly on a shared screen. No app download or social media account required.
How long does it take to set up an interactive wall?
Setup takes about 5 minutes: create your event (60 seconds), display the QR code on slides or signage (30 seconds), open the display link (30 seconds), configure moderation if needed (2 minutes), and test it (60 seconds). You're then live.
Do attendees need to download an app?
No. Attendees scan the QR code with their phone's native camera app (the same way they scan restaurant menus). The submission form opens in their mobile browser — no download required.
How much does an interactive event wall cost?
Free tier (5 most recent submissions with QR Wall branding), Premium tier ($8.99/month for unlimited submissions and downloads), or Professional tier ($14.99/month adding AI auto-moderation and custom branding). Most corporate users choose Premium for regular events.
How do you prevent inappropriate content on an interactive wall?
Three-layer protection: a freeze button (stops display instantly while submissions continue in background), AI moderation on the Professional tier (auto-filters by professionalism level 1-5, only shows appropriate content), and manual review (approve before display). In practice, inappropriate submissions are rare when names are visible.
Can attendees submit anonymously?
Yes. Event organizers can enable anonymous mode, name-optional mode, or require names. Anonymous mode is popular for sensitive corporate Q&A sessions where employees want to ask tough questions about compensation, strategy, or concerns without social anxiety.
What's the difference between an interactive wall and a social hashtag wall?
Interactive walls don't require social media accounts — attendees submit directly via QR code. Social hashtag walls (like Walls.io) aggregate public posts from Instagram, X, and LinkedIn. Choose interactive walls for private, in-room engagement; choose hashtag walls for public social media campaigns.
What happens to submissions after the event?
Premium and Professional tiers let you download all submissions as a spreadsheet. Use this data for post-event analysis: identify recurring themes, surface unanswered questions for follow-up, extract quotes for marketing, and track participation metrics. Free tier doesn't include downloads.
