MuseJS

Muse 2/S EEG Headset Vanilla Javascript Library.

This small Javascript library has no dependencies and enables the use of a Muse EEG Headset (version 2 and S) directly in the browser using Web Bluetooth. The EEG, PPG and Motion sensor data is collected into circular buffers that can be read by the application.

Usage

Simply include Muse.js in your page, and create an instance of the Muse class:

var muse = new Muse();
await muse.connect();

Real-time EEG, PPG, Accelerometer and Gyroscope signals

After a connecting with the headset, the sensor data can now be read:

for (var i=0;i<10;i++) console.log("EEG: " + muse.eeg[0].read());
for (var i=0;i<10;i++) console.log("PPG: " + muse.ppg[0].read());
for (var i=0;i<10;i++) console.log("Accelerometer: " + muse.accelerometer[0].read());
for (var i=0;i<10;i++) console.log("Gyroscope: " + muse.gyroscope[0].read());

The Library supports five EEG channels (eeg[0]-eeg[4]), three PPG channels (ppg[0]-ppg[2]), a 3-axis accelerometer (accelerometer[0]-accelerometer[2]) and a 3-axis gyroscope (gyroscope[0]-gyroscope[2]).

Battery level

console.log("Battery level: " + muse.batteryLevel + "%");

Headset information

console.log("Muse Firmware rev.: " + muse.info["fw"]);
