3.2. Control the Physilog from a mobile application
The Gait Up companion mobile applications allow to control the Physilog 6S sensor. Two modes
are available in the application, for details refer to the user manual of the mobile application.
There is no need to pair your Physilog® with the tablet prior to Bluetooth communication, just
select the Physilog® from the list in the app.
Troubleshoot: If a sensor is not detected by the tablet, gently shake the sensor to enter
detection mode. If the sensor can still not be connected, check that it has enough battery and is
not connected to another mobile device and if necessary ultimately do a reset of the sensor as
explained in section 5.7 Troubleshoot.
Note:
Bluetooth 4.0 or higher is required on the mobile device to be able to communicate with
Physilog 6S.
4. Data Analysis
Physilog® always saves raw data on its internal memory, except when streaming the data live via
Bluetooth using the “IMU stream” functionality of the app. Users have access to the raw data
through companion software called Research ToolKit (RTK). The RTK is available for computers
(PC and Mac). Functions to read raw data inside MATLAB® are also available. Please refer to the
RTK user manual for more details.
USB data transfer
Data saved on the internal memory of the Physilog® can be accessed using USB data transfer.
Therefore, plug the USB cable to the Physilog® and a computer. The Physilog 6S connects to the
computer like a USB key and files can be accessed. One file for each measurement is created and
files are stored in folders depending on creation date (YY_MM_DD). The file name is composed of
a file number (increasing from 1 to 99), the body location (as defined in the configuration, f.ex.
'LF') and the sensor serial number unique part (4 digits). Copy-paste the files to your computer
for analysis. From here you can also rename folders and files or delete the files from Physilog®'s
memory.
Warning: Do not remove the conf.bin file which contains the configuration information,
otherwise the Physilog® will return to a default configuration. If this happens, update the
configuration using the Research ToolKit or contact Gait Up support.
5. Practical Considerations
5.1. Fixation
The Physilog 6S comes with two fixation clips as default attachment accessory, one for the belt
and one for the shoe laces. Additional clips and elastic straps with Velcro patches to stick onto
the Physilog® can be purchased from Gait Up.
