An Idea

Here's an idea I had while studying. I find typing out content from printed material annoyingly slow and painful. So here's an idea to design a device that allows the user to transfer text from printed material to an online format. Important sentences are often highlighted; so, when one spots something important, the user will use the device to highlight it. As the device highlights the words, the device will scan the alphabets and words and type it out automatically on the computer. This would be especially useful to students (AKA ME), more so when we make use of library books, where we cannot make highlights or marks on them.

So, someone good enough in the engineering department please help me construct this device so that I can use it hahaha,
