Now imagine this on the big screen, the ability to not only show content, but interact with it. How do you do this?

The secret, at least for me, is built into the software and hardware I use. Most modern Macs (made after 2013) and modern iPhones/iPads (ones which connect with a Lightning cable) can connect to each other to share the mobile device’s screen.
