Data definition
Axis Definition of Motion Indicators
Regarding the angle, drift (value changes at a constant rate) and hump (small bumps in the value) occur due to the characteristics of the sensor.
Static and Gait indicators
- Among the data that can be measured by JINS MEME, the Static indicator is an indicator that is valid only when there is no walking, touching the glasses with the hands, chewing, etc. When data is measured under conditions other than those mentioned above, it may be detected as a noise flag, output inaccurate values, or not detected. Please note that when measurement is made under conditions other than those mentioned above, it may be detected as a noise flag, output inaccurate values, or not be detected. summaryData is cleansed to remove any suspicious signals.
- The Gait indicator in the data that can be measured by JINS MEME is the data that can be obtained while walking. Please note that JINS MEME cannot accurately measure vibration and movement patterns other than walking.
20Hz data(currentData)
Data can be acquired at approximately 20 Hz. This mode is suitable for immediate acquisition and analysis of precise data such as controller. This data is generated only when JINS MEME and a smartphone are connected via Bluetooth.

15-second interval data (logicIndexData)
The 15-second interval data is the most granular data that outputs biometric indicators. This data is generated only when JINS MEME and a smartphone are connected via Bluetooth. ※”When running sub-applications”, “Normalized”, “sub-index” and “RT algorithm in operation” may not be recorded.

Fast-speed head movement data(fastHeadMotion)
This event counts the first direction and number of times when the head is turned left, right, up or down in a cycle of about 0.2 to 0.9 seconds. The number of times is counted up when the head moves back and forth in succession, and only the final value is returned when the continuous motion stops. The gyro sensor must be turned on to determine by rotation speed. This data is only generated when JINS MEME and a smartphone are connected via Bluetooth.

Slow-speed head movement data(Rotation, slowHeadRotation)
This event is the count of the number of times you make one round every 3-5 seconds while tilting your head at least 45° (start judging from the downward direction in the forward direction). This data is only generated when JINS MEME and a smartphone are connected via Bluetooth.
