A new product called GogglePal allows any pair of goggles to be turned into a smartgoggle with heads up display. The company is currently running a crowdfunding campaign which you can find here.
GogglePal, the first of its kind that is compatible with any pair of goggles, enables you to add augmented reality and a real-time heads up display to any pair of goggles. Simply attach the small GogglePal AR-HUD device to your lens, and you’re ready to unlock a mountain of data, virtual treasures, and games. Whether you challenge yourself or your friends, GogglePal tells your mountain story with the information that matters most.
If you would like to get your hands on a GogglePal you can pledge $99 for a base Sport model or $259 for the Play with additional features.
