Google has sent an unknown “Smart Bluetooth Low Energy” device to FCC for certification. The device with FCC Id – A4R-CAP1, may be the next version of Google Glass based on a few tidbits in the attached documentation.
The FCC filing contains an image in the attached label diagram showing an on-screen mockup of what the digital FCC ID (versus a physically imprinted FCC ID label) would look like to a user on the device. Moreover, it looks a lot like a Glass card.
The FCC’s new e-labeling rules for FCC IDs require that the ID be accessible within three steps for the end user. The document says a left-to-right swipe (touch sensitive!) will get you to the device details area, and a swipe up will get you to the label. This kind of navigation should be familiar to Google Glass users. It also mention an Android-like firmware revision and a battery help, too.
There is the possibility that this is a different gadget which uses Glass-style navigation, but that seems less than likely.
