Detailed Description

This Enum represents all possible packet types. The type of the packet tells you information about what data it contains. When you know the packet type, look at the corresponding enum for information about data mapping (e.g.: Accelerometer enum, EEG enum, etc).

Artifacts packet type will be sent.

Note that this will result in your listener receiving MuseArtifactPacket . We never emit a MuseDataPacket with MuseDataPacketType.ARTIFACTS ; this is only here for use in register / unregister methods.

See also

§ BETA_RELATIVE

com.choosemuse.libmuse.MuseDataPacketType.BETA_RELATIVE

See also

§ BETA_SCORE

com.choosemuse.libmuse.MuseDataPacketType.BETA_SCORE

EEG derived value. Beta band power scores for each channel. This packet contains the same amount of data as an EEG packet and has the same channel mapping.

See also

§ DELTA_ABSOLUTE

com.choosemuse.libmuse.MuseDataPacketType.DELTA_ABSOLUTE

§ DELTA_SCORE

com.choosemuse.libmuse.MuseDataPacketType.DELTA_SCORE

See also

§ DRL_REF

com.choosemuse.libmuse.MuseDataPacketType.DRL_REF

Packet contains raw data from Muse DRL and REF sensors. This packet provides 2 pieces of data. The units of both values are in microvolts.

See also

§ DROPPED_ACCELEROMETER

com.choosemuse.libmuse.MuseDataPacketType.DROPPED_ACCELEROMETER

Packet stands in for n dropped samples of the accelerometer type. Size of the values array for this packet is always 1.

Deprecated:
This is never emitted in an actual Muse session; instead, NaN-filled packets of the basic type (EEG or ACCELEROMETER) are emitted to stand in for dropped packets. This can only appear when reading Muse files written with older versions of the library.

§ DROPPED_EEG

com.choosemuse.libmuse.MuseDataPacketType.DROPPED_EEG

Packet stands in for n dropped samples of the eeg type. Size of the values array for this packet is always 1.

Deprecated:
This is never emitted in an actual Muse session; instead, NaN-filled packets of the basic type (EEG or ACCELEROMETER) are emitted to stand in for dropped packets. This can only appear when reading Muse files written with older versions of the library.

§ EEG

com.choosemuse.libmuse.MuseDataPacketType.EEG

Specifies raw EEG samples.

Values in this packet correspond to EEG data read from the different sensor locations on the headband. The accessors in the Eeg enum define the mapping from packet values to sensor locations. The units of EEG values are microvolts.

The size of the data is unspecified, but it is large enough to hold all the EEG channels emitted by the current preset. In the current version of the library, it is never more than 6 elements long, i.e. it always fits into a 6-element array.

In the future new Muse Presets may be added, which will have extra values.

§ GAMMA_ABSOLUTE

com.choosemuse.libmuse.MuseDataPacketType.GAMMA_ABSOLUTE

EEG derived value. Absolute gamma band powers for each channel. This packet contains the same amount of data as an EEG packet and has the same channel mapping.

See also

§ GAMMA_RELATIVE

com.choosemuse.libmuse.MuseDataPacketType.GAMMA_RELATIVE

EEG derived value. Relative band powers for each channel. Values in this packet are in range [0; 1]. This packet contains the same amount of data as an EEG packet and has the same channel mapping.

See also

§ GAMMA_SCORE

com.choosemuse.libmuse.MuseDataPacketType.GAMMA_SCORE

EEG derived value. Gamma band power scores for each channel. This packet contains the same amount of data as an EEG packet and has the same channel mapping.

See also

§ GYRO

com.choosemuse.libmuse.MuseDataPacketType.GYRO

3-axis gyro data packet A Gyro packet provides 3 pieces of data.

See also
  • Gyro for mapping details.

§ HSI

com.choosemuse.libmuse.MuseDataPacketType.HSI

EEG derived value. HSI values represent the fit of the headband. (known as headband status indicator). This value is not emitted by the LibMuse SDK.

§ HSI_PRECISION

com.choosemuse.libmuse.MuseDataPacketType.HSI_PRECISION

EEG derived value. HSI precision values represent the fit of the headband. This packet contains 4 values corresponding to Eeg.EEG1 , Eeg.EEG2 , Eeg.EEG3 and Eeg.EEG4 . There are no MuseDataPacketType.HSI_PRECISION values for the auxillary channels.

Each channel represents the fit at that location. A value of 1 represents a good fit, 2 represents a mediocre fit, and a value or 4 represents a poor fit.

See also
  • Eeg for mapping details.

§ IS_GOOD

com.choosemuse.libmuse.MuseDataPacketType.IS_GOOD

EEG derived value. Is Good indicates whether or not the last 1 second of raw EEG data on each channel was good or not. Eye blinks or muscle movement can interfere with EEG data and cause Is Good to report that the data is not good. This is emitted every 1/10 of a second to represent the rolling window of the last second of EEG data. This is only useful for real time EEG analysis. This packet only contains 4 values for the 4 sensors on the headband, there is no support for the auxillary channels.

  • Eeg for mapping details.

§ QUANTIZATION

com.choosemuse.libmuse.MuseDataPacketType.QUANTIZATION

Packet contains information about signal quantization. This packet contains the same amount of data as an EEG packet and has the same channel mapping.

Each index in this packet corresponds to the same index in an EEG packet. Quantization occurs when there is a particularly noisy signal, which generally happens when there is not a good contact between the headband and the skin.

Higher numbers are worse; 1 is no quantization, and 16 is maximum quantization.

These values are used under the hood by the library and by Muse Elements in reconstructing the EEG signal and contributing to an overall measure of noise; it is extremely unlikely that you will be interested in them. For measuring noise, it is recommended to instead use the more useful computed values like 'headband_on' or 'hsi'.

Each quantization packet applies to the next 16 EEG packets.

§ THETA_ABSOLUTE

com.choosemuse.libmuse.MuseDataPacketType.THETA_ABSOLUTE

EEG derived value. Absolute theta band powers for each channel. This packet contains the same amount of data as an EEG packet and has the same channel mapping.

See also

§ THETA_RELATIVE

com.choosemuse.libmuse.MuseDataPacketType.THETA_RELATIVE

EEG derived value. Relative band powers for each channel. Values in this packet are in range [0; 1]. This packet contains the same amount of data as an EEG packet and has the same channel mapping.

See also

§ THETA_SCORE

com.choosemuse.libmuse.MuseDataPacketType.THETA_SCORE

EEG derived value. Theta band power scores for each channel. This packet contains the same amount of data as an EEG packet and has the same channel mapping.
