Smart glasses currently have several problems, one of which is being small enough to look "normal" when worn by consumers. Another problem is related to power – the battery is barely enough for several hours of operation.

Bosch seems to be making an attempt (along with many others :-) to solve these problems and offer smart glasses components for a wide range of types of users. It has developed a new approach to the production of augmented reality displays. The technology, called Light Drive, will turn any glasses into "smart" ones, practically without burdening them (they say).

Their claims - The system is 30% flatter than existing solutions and the smallest system of its kind on the market. It weighs less than 10 grams. A MEMS-based bundled light scanner inside the Light Drive System scans a holographic element (HOE) that is integrated into the lenses of the glasses. As with solutions of all tupes of consumer AR glasses, the technology enables the user a hands-free, secure viewing of virtually all information from a connected mobile device. Technology-wise, it reflects light from a holographic element directly into the retina, projecting alerts, calls, wake-up calls, appointment reminders and short message services or navigation information. Besides, the technology will be ideal for notes-based information such as task lists, shopping lists, recipes or assembly instructions that are particularly practical, where it is important to keep your hands free.

Sort of a standard description for AR, but their new approach has caught my eye and gives me reason to make note and watch their developments. But, to be sure, AR is actually about valuable applications and content, so a bit of a chicken and egg situation which an acceptable consumer friendly type of glasses might begin to hatch. I am monitoring with interest...
