The Raspberry Pi relies on a while loop to check for triggers from the AR app. When it detects a change, it sends a signal to the Phillips Hue gateway to change the light value.
When described at that level, it's not clear why the AR app couldn't just signal the gateway, directly.

It certainly doesn't sound like the Pi, itself, is doing anything that could be construed a AR. It's just acting as glue. Unless I'm missing something, the headline is is definitely misleading.
