The Verge managed to photograph a yet unannounced LG smart watch that really looks the business. What do you think?
It turns out this is an Android Wear watch with a special skin on top. LG and Audi worked together to develop this watch to match the design of the Prologue car, but also included extra hardware to communicate with the car.
NFC is included to help establish a secure connection between the car and the watch, which then allows you to unlock the doors. Since NFC can work without the battery, the driver should still be able to unlock or lock the doors even when the watch battery is dead.
Then there are biometric sensors that could feed information such as the driver’s body temperature and heart rate to the car’s onboard computer. This could be used to automatically control the air conditioning or heat in the car.
