Linear Acceleration

Function Summary

• Show Linear acceleration on the graph and save on CSV file
• You can select LinAccX/Y/Z from graph item popup window

Use case

• When you want to see acceleration data without gravity effect
  • Vertical movement
  • Horizontal movement

How to use

Base Flow

1. Tap each graph to show graph item window
2. Select LinAccX/Y/Z from the list

(You can see the data in exported CSV)

Limitation⚠

• Linear acceleration is calculated from raw acceleration and Quaternion. Quaternion has a drift when rapid movement, so LinAcc is also drifted.
• Be careful of the orientation of the sensor axis. The effect of gravity component is removed from the acceleration, but the directions of "horizontal" and "vertical" still need to correspond to the sensor axis.
