Info Pane
This page provides information on the Info pane, which can be accessed from the View tab or by clicking on the
icon in the toolbar.
Overview
The Info pane can be used to check tracking in Motive. There are four different tools available from this pane: measurement tools, Rigid Body information, continuous calibration, and active debugging. You can switch between different types from the
context menu. The measurement tool allows you to use a calibration wand to check detected wand length and the error when compared to the expected wand length.


Measurement Tool
The Measurement Tool is used to check calibration quality and tracking accuracy of a given volume. There are two tools in this: the Wand Validation tool and the Marker Movement tool.

Wand Validation
This tool works only with a fully calibrated capture volume and requires the calibration wand that was used during the process. It compares the length of the captured calibration wand to its known theoretical length and computes the percent error of the tracking volume. You can analyze the tracking accuracy from this.
Steps
In Live mode, open the Measurements pane under the Tools tab.
Access the Accuracy tools tab.
Under the Wand Measurement section, it will indicate the wand that was used for the volume calibration and its expected length (theoretical value) depending on the type of wand that was used during the system calibration.
Bring the calibration wand into the volume.
Once the wand is in the volume, detected wand length (observed value) and the calculated wand error will be displayed accordingly.
Marker Movement
This tool calculates the measured displacement of a selected marker. You can use this tool to compare the calculated displacement in Motive against how much the marker has actually moved to check the tracking accuracy of the system.
Steps
Place a marker inside the capture volume.
Select the marker in Motive.
Under the Marker Measurement section, press Reset. This zeroes the position of the marker.
Slowly translate the marker, and the absolute displacement will be displayed in mm.
Rigid Bodies
The Rigid Bodies tool under Info pane in Motive displays real-time tracking information of a Rigid Body selected in Motive. Reported data includes a total number of tracked Rigid Body markers, mean errors for each of them, and the 6 Degree of Freedom (position and orientation) tracking data for the Rigid Body.

Continuous Calibration
Continuous Calibration allows for the update of Calibrations in real-time. See the article Continuous Calibration (Info Pane) for details on using this tool.
Active Debugging
Active Debugging is a troubleshooting tool that shows the number of IMU data packets dropped, the largest gap between IMU data packets being sent, and IMU misalignment.
When any value exceeds the Maximum settings at the bottom of the pane, the text will turn magenta.


Drops
This column shows the number of drops that have occurred during the past 60 seconds.
IMU % Drops
This column denotes the number of IMU packet drops that an IMU Tag is encountering over 60 frames.
Max Gap
Max Gap denotes the number of frames between IMU data packets sent where the IMU packets were dropped. i.e. in the image above on the left, the maximum gap shows there were no frame gaps where IMU packets were either not sent or received. The image on the right has a gap of 4 frames where the IMU packets were either not sent or received.
Alignment
This column shows the degree to which the alignment of the IMU varies from its expected alignment.
