Mobile Bridge for Unreal is a real-time interaction system that connects mobile devices directly to Unreal Engine.
Visitors or players scan a QR code, join a shared room, and instantly gain control over in-game elements through a responsive web interface.
Overview
The bridge transforms smartphones into flexible, low-latency controllers for installations, events, and multiplayer experiences.
Buttons, sliders, touchpads, and custom UI panels are generated dynamically based on context and user role.
Each device communicates live with Unreal, enabling synchronized inputs and feedback across all connected users.
Experience
From interactive exhibitions to multiplayer prototypes, the system allows rapid onboarding without downloads or setup.
The connection process is as simple as scanning and playing.
Inputs are sent to Unreal in real time, giving players the ability to move characters, control lighting, vote in audience polls, or manipulate installations from their phones.
Technical Highlights
- WebSocket-based communication with HTTP and OSC fallback
- Room and role-based session management for multi-user experiences
- Adaptive input coalescing and heartbeat for stability
- Real-time operator console with analytics and reconnect tools
