built on open source software
Our 2D Gait Lab software is built on open source software
Written with the Python programming language, the application uses the pose estimation library mediapipe by Google to identify the body landmarks (ie, capture dots) and calculates the angles in real-time.
Whereas mobile software can often be far less than real-time (the actual landmarks are heavily interpolated), the mediapipe library is now very robust and with advances in modern computing power, especially the ARM based CPUs available for Mac OS and coming soon for Windows, it presents another option for tools at the disposal of clinicians who need access to tools that assist with making 2D gait analysis.
Warning or error messages on install
Windows defender
The demo software may trigger a Windows defender warning - please click on trust this software and it will run as intended. The final release software will not have these warnings.
Mac Security - method 1 (updated as of 21st Nov '23)
Only for new versions of the M-series and non-M series downloads
As with the Windows Defender warning message, you may also get a similar warning from the Mac OS. See the image instructions below for a step by step guide - this is required only on the first run of the app.
1. When clicking on the .app file after unzipping, you may be presented with a software warning (see pic 1). Just click OK
2. You will need to go to your settings and find the Security and Privacy icon. Click on that to allow the app to load.
3. Make sure you have selected the "General" tab and click on the "Open Anyway" tab that is next to the "HSF2D_gait_app" was blocked from use because it is not from an identified developer warning message
4. Go back to the .app file - double click and when you see the pop up message with Open / Show in Finder and Cancel - Click OPEN.
And voila.... the app has now been installed correctly. This is only required on the first install and open of the app. After that you can open the app as normal.
Mac Security - method 2 (for older installations)
Only for older versions (no longer recommended - but may be needed if app is auto-quarantined)
As with the Windows Defender warning message, you may also get a similar warning from the Mac OS. Go to your security settings and click allow (as Mac OS blocked the initial loading of the application).
If the HSF2D_gait.app file does not run and MacOS states that the file is damaged and can't be opened, you will need to unquarantine the application first. Please do the following (do not press enter until the end):
1. Open the terminal (type terminal in the MAC search icon at the top right of the system menu bar)
2. Type the following exactly:
xattr -d com.apple.quarantine
3. Press the space bar once (the line should now be as above but with a space at the end)
4. Then drag in the HSF2D_gait.app file
5. Press Enter
Now the application has been unquarantined. You can now launch the application.
Once again, the final release, non-demo software will not have these warnings.
