Google is rolling out some changes to Google Now on Tap that should make the feature much more useful. With the latest updates, you'll be able to manually tap to select which portion of the screen you'd like more information on.

Google Now on Tap update brings manual text selection, image search

Says Google:

If you use Now on Tap in an app, email, chat, or news article with a lot of text, sometimes the results aren't as precise as you'd like. Starting today, you can give Google a nudge by selecting exactly what you want help with, and you'll get the right information, right away.

Perhaps just as notable is that Now on Tap can also now identify content in images. And not only can you use the feature to nab more information about a photo you stumble upon in an app or on the web, but you can also use Now on Tap in real time with your camera app:

And for certain images or objects, you can also search via your camera app in real time. If you're standing in front of the Bay Bridge, you can hold up your phone, open your camera app, touch and hold the home button, and get a helpful card with deep links to relevant apps. This works for more than just famous structures like the Bay Bridge, you can even point your camera at a movie poster or magazine and get additional info about what you're looking at.

For those who were a bit underwhelmed by Now on Tap since it launched with Android 6.0 Marshmallow, these additions should go a long way towards making the feature that much more useful.

As Google notes, word definitions are only available in English at the moment, but will land for other languages in the coming weeks.
