Choose an open area with a simple background — no other people or objects should appear behind the participant.
Ensure there is enough space (about 3 meters from the device) for circular walking.
A circle with a diameter of about 1 meter is sufficient.
Mark the circle on the floor with visible tape or other markers.
Ask the participant to wait outside the camera view.

The operator taps “Go to Measurement Screen.”
Enter the participant’s ID in the participant ID field.
For details about participant IDs, please see [About participant IDs].
Once entered, the same ID will appear in the dropdown list for future measurements.

When the camera activates, a guide overlay will appear on the screen.
Align the guide with the circular floor marker and fix the camera position (a tripod is recommended for stability).
Now you’re ready to measure.

◆ About the Level Indicator
The measurement screen displays the device’s angle detected by the gyroscope sensor.
This value is for reference only and can be used as a guide to keep measurement conditions consistent.

The participant should stand on the far side of the circle as seen from the camera, facing either to the left or to the right.
When the system detects the participant correctly, the human-shaped silhouette turns from red to green.

The operator taps “Start Measurement.”
The background turns black, and the participant begins to walk around the circle.
Measurement starts automatically once walking is detected.
Continue walking until the progress indicator reaches 100%.
When the measurement is complete, the screen will automatically switch.

Tap the [ i ] icon next to each item to see explanations of the analysis results.
If you have notes, enter them in the memo field and tap “Save.”
After tapping “Done,” the data is saved locally on the device, and you’ll return to the home screen.
