Vincent's wife is blind and he's thinking of using a Harmony remote and the screen reading app on her iPhone to use it. How does that reader work? Leo says that's a great idea and some phones have free built-in infrared, making the phone a smart remote. The Harmony remote can talk to the phone via Bluetooth, though. The iPhone also has great accessibility features, if the app developers take advantage of them. But Leo says that the iPhone is the best option.
