"Sometimes my mind tends to stray from the message and I could see how having something interactive would keep me focused."

I have yet to find a single interactive tool that did not tend to increase distraction and to cripple focus.

“Multi-tasking is the reflex. Single-tasking is the discipline.”

—Patton Dodd (via Trinity Forum)

I, too, suffer from distraction. My best remedy, I find, is to seek to engage by reading the chapters around the sermon text.
