Make it easy to see, touch and voice control your iPhone: How to make your phone accessible

I have a friend who is 75-years old and has Parkinson's disease. He's also crazy about his iPhone and tech in general, and eager to buy the latest and greatest gadgets to hit the market. More importantly, his smartphone is his lifeline to the outside world. He uses it for watching and reading news – one of his favorite pastimes – and for keeping up with the world around him. He also goes straight to his smartphone to order food delivery, use car services like Lyft and Uber, and contact people in emergencies.
