On March 22, according to the Financial Times, people familiar with the matter said that Google was developing a smart watch. But unlike Google Glasses, another wearable computing device, this product is not from Google's X Lab, but from the Android team.

People familiar with the matter said that Google's purpose of developing smart watches is to use them as an extension of Android smart phones, but it is not related to Samsung's smart watch development project. It is unclear when the product will be released.

Since the launch of Google Glasses, wearable computing seems to have become an important investment direction of Google. The company also introduced a shoe that can speak at the SXSW technology interaction conference, further enriching the camp of wearable computing devices.

A patent applied by Google in 2011 seems to support this rumor. The patent is related to a double screen smart watch, which is equipped with not only a touch user interface, but also a camera. In addition, it was rumored earlier that Apple was developing an iWatch smart watch, and Samsung executives said not long ago that they were "already developing smart watches".
