I just learned about Snapanda from David Kapuler's blog, Technology Tidbits: Thoughts of a Cyber Hero, which is a great resource!
Snapanda is a new app for Android (iPhone version coming soon) that lets you get the definition of any written English word through your smartphone camera. The app uses OCR technology to read the word and then gives you the definition.
This is a great app for students, especially English Language Learners, to support them in learning English. Not knowing the definition of a word can lead to misunderstandings and frustration.
