Technical requirements for
smooth operation
VRClass uses modern technologies to ensure seamless interaction between the web interface and the VR simulation. Below are key specifications for hardware, software, and network infrastructure.
1. Hardware setup (VR station)
The system is currently in a transition phase between PCVR (wired setup) and a fully wireless standalone mode.
Primary target platform
Meta Quest 3
- Project status:
Currently in an intensive phase of development and optimization.
- Long-term goal:
Fully wireless operation without the need for a high-performance PC.
Legacy support
HTV VIVE / Vive Pro
- Project status:
Currently fully functional (PCVR operation).
- Note:
This setup requires a connection to a high-performance PC.
| Component | Minimal requirements | Recommended specifications |
|---|---|---|
| Graphics card | NVIDIA GTX 1060 | NVIDIA RTX 3060/4060 or higher |
| Processor | Intel i5-4590 / Ryzen 1500 | Intel i7 / Ryzen 7 (newer generation) |
| RAM | 8 GB | 16 GB |
| Operating system | Windows 11 | Windows 11 |
Specifications for current PCVR setup (HTC Vive):
Minimum requirements:
Graphics card: NIVIDIA GTX 1060
Processor: Intel i5-4590 / Ryzen 1500
RAM: 8 GB
Operating system: Windows 11
Recommended specifications:
Graphisc card: NIVIDIA RTX 3060/4060 or higher
Processor: Intel i7 / Ryzen 7 (newer generation)
RAM: 16 GB
Operating system: Windows 11
2. Control interface (web browser)
Teachers and facilitators can access a responsive dashboard from any modern device. The interface is built on a modern TALL stack (Tailwind CSS, Alpine.js, Laravel, Livewire), enabling fast, real-time interactions without page reloads.
Backend
- PHP (8.1+)
- Node.js (20.19+ )
- PHP (8.1+)
Frontend
- Blade templates
- Alpine.js (lightweight interactivity)
Styling and support
- Custom styling (Stylus)
- Supported browsers: Chrome, Edge, Safari
- JavaScript must be enabled
3. Network and communication (real-time sync)
Communication between the web interface and the VR headset relies on industry-standard, low-latency protocols. This ensures that the virtual classroom responds immediately to the teacher’s actions.
Protocol MQTT
Message Queuing Telemetry Transport is used as an industry standard for real-time data transmission.
Connection logic
Commands are distributed in a targeted way (e.g., vr_lobby_5/avatar_1) , ensuring that instructor input affects only specific objects within the virtual environment.
Network requirements
- Stable internet connection.
- Firewall: specific ports must be open for communication with the MQTT broker.
- Wi-Fi 6 (802.11ax) is recommended for the upcoming full support of Meta Quest.
