Record Section

This section is the main control unit for the sensor insoles. Setting up the record settings and labeling are done here as well as starting and stopping the measurement. Live data from the Sensor Insoles is displayed in the widgets.

Overview

The following picture shows an overview of the Record Section with the standard wording used in this documentation:

Widgets

Widgets display a preview of the data received by the mobile phone when connected to sensor insoles. The data preview is a live stream sent with a fixed sample rate of 25 Hz and independent from your actual data recording settings.

Widget Widget Name Description
Pressure Distribution Shows a 2-dimensional heat map of the pressure distribution. The color scheme ranges from white (no pressure) to dark red (high pressure).
Intensity Displays the load intensity acting on the sensor insole. The intensity ranges from 1 line (low load) to 3 lines (high load).
Note: In this widget, you can carry out the zeroing.
Total Force The bar graph displays the total force acting on the left and right sensor insole.
Acceleration The bar graphs display the acceleration of the left and right sensor insole in X/Y/Z direction.
Video Synchronization The barcode must be filmed about 4-5 seconds to allow automated synchronization of sensor insole data with external videos. One or more video channels can be used.

Zeroing

In order to avoid offsets in the pressure data of your sensor insoles, a manual zeroing should be carried out before starting a measurement. The intensity widget in the Record section allows manual zeroing by simply tapping on the left and right sensor insole pictograms.

Zeroing Instruction

  1. Make sure no pressure is applied on your foot when performing a zeroing. To do so lift the foot of the ground in a standing or sitting position.
  2. Tap on the corresponding insole outline to the lifted foot in the Intensity widget.
  3. Repeat this step for the opposite foot.

Automatic Zeroing

The firmware of the Sensor insoles additionally runs an automatic zeroing algorithm. This does not replace the need for manual zeroing before starting a measurement, but ensures continuous zeroing during operation.

Starting a measurement

The start button is used for starting measurements. It is a toggle button which switches to "Stop" once a measurement is started. Pressing "Stop" will stop a measurement.
