Android USB communication:

Info:

Even though all smartphones support USB, communicating over USB is not a simple task. We have however implemented the USB interface for Android, using the Android Debug Bridge. The USB protocol was designed to work with the Android USB tracker plugin of  FaceTrackNoIR.

You can test the USB communication, even when you have not yet upgraded the App.

Setup:

USB Settings

To use USB communication, you must:

• Connect your Android device to your PC using a USB cable.
• Match the USB port number of FacePoseApp with the FaceTrackNoIR plugin (or the DUT4FPA utility). The picture above shows an example of this.
• Enable USB debugging on your Android device. For this, you must first enable 'Developer options' (usually done by tapping the 'build number' 7 times (for a detailed description, see enabling USB debugging
• Install the USB driver for your device, see OEM drivers.
• Of course, you must also SET the 'enable USB' switch to make it work.

Testing communication:

FaceTrackNoIR

If you have FaceTrackNoIR already, you can test communication by selecting the Android USB tracker plugin. After pressing START, you can open the USB tracker settings page to see if data arrives.

Droid USB Test for FacePoseApp utility (DUT4FPA)

We have created a small Windows utility that can be used to test USB communication. You can also see the status of your Android device, to see if it is capable of communicating via USB:

The DUT4FPA test tool (installer, also includes the FaceTrackNoIR plugin) can be downloaded here.

Remark: Click the link to download the installer. Since it is an EXE file, your browser will probably warn you. You can also right-click the picture and choose "Save target As..." and let your virusscanner do its thing.
