Can you explain how Focused Reading Mode works?

Many people prefer a distraction free screen without a lot of text. Voice Dream Reader is equipped with Focused Reading Mode. To activate, pinch the screen with two fingers, and the speech text area will be reduced to about a third of the screen in the middle. In addition, the text will be scrolled automatically so that the word and line being spoken is always in the middle. To bring back the full screen, un-pinch or expand the text area with two fingers. Keep in mind that you finger tips must start out from inside the reduced text area.
