Here you can see the secondary driver wearing it during the match as well:

So, time for some technical talk
We hosted network tables on our robot to which both the robot's sensors (infrared, pressure, gyro, etc.) and data from the coprocessor (raspberry pi with pi camera tracking with OpenCV). This data was updated throughout the match, and we had a jar file running on the driver station laptop using the windows networktables library to access the network tables on the robot. When setting up the Vuzix smart glasses, an ADB port forward was used to connect a port on the laptop to the smart glasses. The jar on the laptop created a socket at the same port and the Android app created using Android Studio read from the appropriate TCP ports. Then, the data was received by the smart glasses and depending on the values that the glasses received, lights were colored or uncolored on the android app.

Lemme know if any other details are requested

Did the drivers connect a USB cable before each match or did they not wear glasses before the match or attach it? Did you have any issues with this with the refs? How did you guys come about the Vuzix and what's the story behind it?
