Head Tracking Device
- We use a custom head tracking device made in house using the arduino and a 9 dof IMU
- Software ( BIACTracker ) is a java applet written in processing that reads the IMU's yaw/pitch/roll output
- The software can interact with any type of media running through VLC Player as long as VLC's http interface is configured. This is used to pause/resume media as a motivation to keep the head still.
- The pause threshold is configurable through software and will automatically resume after 3 seconds.
Head Tracking Instructions
- The Mock scanner now operates through a single computer. Once logged in there will be a BIACTracker icon on the desktop ( this opens the java applet ).
- The tracker will have two LEDs that show it its connected and on … a green one on the black case containing the arduino and a blue LED on the IMU that is placed on the headband. If both of these are on, then the tracker is connected and powered on. If they are off, just plug in the USB cable connected to the black case.
- Once the tracker is powered up, open the BIACTracker applet.
