Google is also likely to unveil some advances in wearable technology. In March, Google released ``Android Wear,'' a version of its operating system tailored to computerized wristwatches and other wearable devices. Although there are already several smartwatches on the market, the devices are more popular with gadget geeks and fitness fanatics than regular consumers. But Google could help change that with Android Wear. Android, after all, is already the world's most popular smartphone operating system.
Google may also have news about Glass, including when the company might launch a new and perhaps less expensive version of the $1,500 Internet-connected eyewear. Google will likely have to lower the price if it wants Glass to reach a broader audience. But that's just one hurdle. Convincing people that the gadget useful, rather than creepy, is another one.
