Emoji Reactions
Emoji reactions give your audience a lightweight way to express themselves during a live event — just like reacting in a video call, but for in-person sessions.
How it works for attendees
Section titled “How it works for attendees”Attendees tap an emoji in the Action Bar to send a reaction. Available emojis: 👏 ❤️ 😂 👍 🔥 🎉
When a reaction is sent:
- A floating emoji animates across the screen on all connected devices
- The reaction count increments in the event footer
- Reactions appear on the Display View (projector screen) for the whole room to see
- A subtle haptic vibration confirms the tap on supported devices
Reactions are anonymous — there’s no attribution to individual attendees.
How it works behind the scenes
Section titled “How it works behind the scenes”Reactions are designed for high throughput. When hundreds of attendees react simultaneously:
- Reactions are batched in 200ms windows in the backend to prevent overwhelming connected clients
- Batches are broadcast to all connected devices (attendee, admin, display) via WebSocket
- Reaction counts are tracked in memory and periodically persisted to the database
- The system handles thousands of simultaneous reactions without performance issues
Display formats
Section titled “Display formats”You can choose how reactions appear on attendee devices in Event Settings:
| Format | Behavior |
|---|---|
| Floating | Emojis float up from the bottom and fade out. High visual energy. |
| Bar | A compact bar shows recent emoji counts. Subtler, less distracting. |
