We have 2 exciting pieces of news to share.
1/ New LibMuse Unity Example Application.
We are happy to announce a Unity 3D example application that illustrates how to integrate LibMuse into the Unity Game Engine. This application will show you how to detect, connect to and receive data from both the 2014 and 2016 Muse headbands using a C# Unity script. The example can be used as in your own applications or you can use it as a starting point for additional modifications.

2/ LibMuse for iOS and LibMuse for Android have been updated to 5.13.0 API 4.
We’ve updated LibMuse for both Android and iOS to version 5.13.0. This release contains a new IS_GOOD data type for EEG data, fixes for the accelerometer and gyro data types and some stability fixes. The full changelog is below.
Changelog for LibMuse 5.13.0:
Features introduced in this release:
- New IS_GOOD data packet type which indicates if the last 1 second of raw EEG data is good or contained too much interference and should not be used.
- Introduces ReaderPlaybackListener which provides notifications when a ReaderMuse finishes playback of a file or playback was interrupted.
Issues addressed in this release:
- Corrected the timestamp for all EEG derived packets (ALPHA_ABSOLUTE, ALPHA_RELATIVE, ALPHA_SCORE, BETA_ABSOLUTE, …). Previous versions were returning -1 for the timestamp. This has been corrected to be the time the packet was generated by LibMuse.
- ACCELEROMETER axis values were inconsistent between Muse 2014 and Muse 2016 headbands. Axes for both headbands have now been mapped to X, Y, Z in a Right Hand Coordinate System as shown in the new documentation. - FORWARD_BACKWARD, UP_DOWN and LEFT_RIGHT have been deprecated and the sign of UP_DOWN and LEFT_RIGHT has changed as a result of the new axis mapping.
- ACCELEROMETER values are now displayed in G for both Muse 2014 and Muse 2016 headbands. Previous releases had Muse 2014 values displayed in mG.
- The GYRO axis values now map to the same axes as the ACCELEROMETER values where GYRO indicates rotation about that axis.
- ACCELEROMETER and GYRO values for Muse 2016 headbands running firmware versions 1.2.9 and 1.2.13 have been corrected. LibMuse was returning +/-4G for the accelerometer and +/-1000 degrees per second when the ranges for these firmware versions was actually +/-2G and +/-245 degrees per second.
- Fixed a crash that occurred if you tried to connect to a headband while the Bluetooth on the device was turned off.
- Fixed a crash that could result while attempting to reconnect to a headband after the device had been locked and unlocked.
- Fixed a crash that resulted from calling disconnect when the headband was already disconnected. The second call to disconnect is now ignored.
