Imagine seeing related maps, pictures, artwork, architectural layouts, bible translations appearing on your iPad, Kindle Fire, or similar tablet, as your pastor gives the message or sermon.
This is the Second-screen experience.
A learning church could harness this technology in the form of an app and allow for people listening to a sermon or message to see pictures or artwork of the people being mentioned in the message appearing on their iPads. People listening could have maps of biblical locations or ancient kingdoms instantly displayed on their iPads as the pastor mentions them.
Think of Wikipedia or the Glo Bible, but in real-time, matched to the sermon you are listening to in the palm of your hand.
The ability to harness and enhance a message or sermon synchronously using second-screen app technology would have a powerful visual impact and increase learning and understanding.
