The Haifa company, Israel, was one of the first to introduce these devices last year and is already accepting orders for 2018.
Smart glasses for cycling are already available for purchase. You will get navigation, speed, heart rate and other important information without losing valuable visual static. They even record your trip in HD (with sound), so you can check your performance after the trip.
You have several control options, including buttons on the handle bars, a touch pad on the glasses themselves or voice commands. You will need to connect the application with satellites on your phone, but it will also allow you to exchange data with other fitness applications.
