An array of capacitor plates is disclosed wherein each plate is the foundation on which a page of printed material is built. Capacitance is sequentially detected between nearby pages to determine where capacitive interaction fails, thus determining the page opening. Any number of pages can be scanned in this manner without the use of buttons, switches or pointing devices. Page openings can be determined to provide automatic audible narration that is pertinent to the contents of each page, even when randomly opened.
