Raw data export

We are excited to announce the ability to export your raw IMU data direct from IMU Step Desktop.

What is raw IMU data?

Raw IMU data is all the information measured by the Low G, High G, Gyroscope and Magnetometer on board our latest BlueTrident Inertial Measurement Unit.

What is the raw data export?

Using IMU Step, we quantify the impact of every step taken using both the Low G and High G accelerometers on the BlueTrident sensor. Alongside this, we still measure all the angular velocities and compass heading values from the Gyroscope and Magnetometer (which will be used as we keep innovating new IMU Step metrics and insights). The raw data export gives you access to this data.

IMU Step Desktop 2.6.2 will provide you with the ability to either:

  • Process your data as per usual (download, upload, process in cloud, display in dashboard)
  • Process your data as per usual AND save all the raw IMU data
  • Save all the raw IMU data ONLY

Figure 1 - Final confirmation page

One of these three options can be chosen on the final confirmation page before processing your data (as seen in Figure 1).

The raw IMU data comes in 3 .csv files:

  • Low G and Gyroscope data
  • High G data
  • Magnetometer data

Note the Low G and Gyroscope data come in the same .csv file as they have the same time stamps associated with them. The High G and Magnetometer both have their own unique timestamps, so they come in separate .csv files.

Why would I want the raw data?

If you are interested in gaining even more insight from our BlueTrident IMUs and diving deeper into the raw IMU data measured at on the lower limbs, you can analyze this yourself using any proprietary algorithms you may have.  

Cross-product compatible firmware

The BlueTrident sensor is compatible with Vicon’s Capture.U and upcoming Nexus release. This new firmware update allows you to use the same sensors with those products. Get in touch with your local IMeasureU representative to learn more!
