Connect Your Heart Rate to VRChat Worlds: Pulsoid to MIDI

Updated: Sep 30


Heart rate integration with avatars via OSC has already captured the attention of VRChat players, and we're taking it a step further. We’re thrilled to introduce a groundbreaking feature that will transform how you experience VRChat: the ability to link your heart rate directly to VRChat worlds. Imagine your virtual environment reacting dynamically to your emotional and physical state, creating an immersive experience like never before. While we’re still working on integrating this feature into your favorite worlds, we need your help to make this vision a reality. Read on to learn how this innovative feature works, why it’s going to be amazing, and how you can be part of bringing it to life!


What Is Heart Rate Integration?

Our new heart rate integration allows VRChat worlds to access players’ heart rate and respond to it in real-time. Here's what you can look forward to:


  • Dynamic Visual Effects: Watch as the environment adjusts its colors, lighting, and animations based on your heartbeat. For example, a racing heart might intensify visual effects, while a calm, steady rate could create a more serene atmosphere.

  • Adaptive Gameplay: Games and activities within VRChat worlds can adapt to your heart rate. For instance, if your heart rate spikes during a thrilling chase, the game could increase the intensity or introduce new challenges.

  • Personalized Experiences: Each player's unique heart rate can create a personalized experience that evolves with their emotional state, adding a new layer of immersion and engagement.

  • Group Dynamics: Picture a world where your collective heart rate impacts the environment! Worlds can calculate the average heart rate of all players and trigger events or rewards based on maintaining a specific group rate. For instance, keeping a certain heart rate range might unlock special features or world-changing effects, encouraging teamwork and adding a cooperative twist to your VR experience.


How Heart Rate to VRChat Worlds Work


  • Heart Rate Monitoring Device: To use this feature, you'll need a heart rate monitor. This can be a dedicated device or compatible smartwatches and bands. Check our comprehensive list for supported devices.

  • Connect Your Device: Link your heart rate monitor to your Pulsoid account using our mobile app.

  • Pulsoid to MIDI: Your heart rate data will be sent from your Pulsoid account to a local MIDI loopback. Keep the Pulsoid page open at all times to ensure the data remains accessible on your computer.

  • MIDI to VRChat World: VRChat worlds can read data from MIDI. Integration is needed within the world itself, so this feature will only work in worlds that have added the necessary integration.

  • Magic✨: Once integrated, worlds can use your heart rate data to display dynamic effects and adjust gameplay based on your personal heart rate or the average of all players. The possibilities are endless!
