You’ve probably heard of some speech-recognition efforts, like Apple’s Siri and the dictation program Dragon NaturallySpeaking. But the world is teeming with apps that recognize other sights, sounds and stimuli. Here’s a taste.
Evernote (free; Android, iOS, Mac, Windows): Evernote is the popular notepad-of-all-trades app that keeps your notes synchronized across all of your gadgets. If you snap a photo of something that includes writing (or paste in such an image), even handwriting, its behind-the-scenes optical character-recognition algorithms decipher the writing as text. The accuracy isn’t quite good enough to convert the writing into typed text, but it’s good enough to let you perform searches on handwritten notes. That is, you can pull up the image of your scanned or photographed handwriting by typing a keyword into the search box.
