Screen text reader and sender.

I am not well versed in anything computer science related. So I'll do my best to explain what I need and will be happy to clarify any questions. In short, I need a program that can read text off a computer screen from a distance to then be sent wirelessly to a separate device such as an iPhone or tablet. Ideally, This would run off a device not associated with the computer it's reading off. It would read the text and seamlessly upload the text to whatever device is also connected to the program. I'm open to suggestions on how this should be implemented and executed.
