Google Glass Can Use iPhone's Data Connection Via Bluetooth
Google Glass is a tiny computer that mounts to an eyeglass frame and has a small display that is visible only to the user. The wearable device has a built-in camera that sees what the wearer sees, GPS, Wi-Fi, and Bluetooth connections. The glasses can handle many of the same tasks as smartphones, including giving driving directions, sending text messages, showing weather reports and more.
Some potential purchasers were concerned that Glass would only be compatible with Google's Android smartphone operating system, but it appears the device will be able to tether to any smartphone via Bluetooth. Topolsky writes:
The device gets data through Wi-Fi on its own, or it can tether via Bluetooth to an Android device or iPhone and use its 3G or 4G data while out and about. There’s no cellular radio in Glass, but it does have a GPS chip.
Google hopes to put Glass on sale sometime before the end of the year for less than $1,500.
