This is where visual search comes in: You can snap a photo of a person or thing, and the app in theory tells you what or who it is and provides relevant links to information about that person, place, or thing.
In a recent video the two apps were put to the ultimate 2016 test: Could they identify Donald Trump from a picture and tell the user about him?
It must be pointed out that CamFind representatives uploaded the video performed the test, so take note of that when you see how the test pans out.
That said, the results are interesting, with CamFind being able to accurately identify Donald Trump and provide the user with relevant information about him.
The technology still has a long way to go before you start using it over traditional text-based search engines like Google, but in specific situations where you can take a picture of whatever it is you are trying to identify or learn about, this is at least worth trying.
Blippar, on the other hand, seemed much less accurate and took longer to show information it thought was relevant to your search.
