Google patented the gesture for research

After the patent on the method to unlock your phone, Google has certainly not ceased to require the registration of new content, among them a gesture created specifically to enable searching.

The idea is simple and functional designs a letter, then circle the word or text to search for and like magic Android does the rest.

In the example above we see this concept applied to the letter "g", which as you may have guessed will launch a Google search, but if we had drawn a "w" we would have consulted Wikipedia. As you can see there are so many possibilities and it is said that they are all limited to the letters of the alphabet, just that the gesture is easily reproducible.
