Google on Tuesday introduced three new search features that make it clear mobile technologies are leading the way in new developments from the search giant.
One of the technologies driving this growth is speech recognition. With Voice Search, you don’t have to type on a tiny touchscreen. You can just speak your query and the answer is on the way.
Search by Image
Today we’re introducing Search by Image on desktop. Next to the microphone on images.google.com, you’ll also see a little camera for the new Search by Image feature. If you click the camera, you can upload any picture or plug in an image URL from the web and ask Google to figure out what it is
Whether you type, speak or upload a photo, once you’ve indicated what you’re looking for the next step in your search is to sift through the results and pick one. To make this faster, last year we introduced Google Instant, which gives you search results while you type.
