Google Glass won’t be the only popular smart glass available for long; Lenovo, China’s PC powerhouse, recently revealed its competing prototype. The glasses include necklace-style battery pack that connects to the back of the glasses via a blue wire, but the battery pack could be a hit or a miss. Some may see it as an opportunity to accessorize; eventually, the color and design on your battery pack could be a form of self-expression. Others may see it as a nuisance, but it all depends on if the technology catches on. Lenovo is teaming up with Vuzix, a U.S. smart glass hardware producer, to bring a smart glass product to China. Features will include the Chinese language pre-programmed, voice recognition, mapping, and other services.
