In recent years, we are used to searching words in electronic documents such as PDFs,
Powerpoints, Word Documents, and so on. Whenever we have a large document and we
need to find a specific word or sentence - with a few keyboard commands - we can easily
find it, and all occurrences are highlighted to make locating it easier. On the other hand,
when we think about physical documents (e.g. printed documents, magazines), there is
no such mechanism that allows us to search words or sentences on it. Our method helps
creating a search query on physical documents by allowing the user to point a camera
to the document, search for words or sentences, and the solution will highlight them
with augmented reality technology.
