Scroll and Navigate PDF Pages by Tilting Your Phone

Smart Scroll for Mobile Devices

Free RotoView PDF Reader app makes document navigation simple

HOUSTON – April 29, 2015 – INNOVENTIONS, Inc., an early pioneer in motion-enhanced smartphone display technology, has released the free RotoView PDF Reader app, giving Android users an entirely new way to scroll magnified PDF documents and switch between pages with one hand just by tilting their phone. Using natural tilting motions to scroll and change pages eliminates the need for repetitive touch screen gestures which block the user’s view and leaves fingerprints and dirt on the screen.

“We’ve been developing the RotoView technology for many years, continually demonstrating how intuitive and efficient tilt-to-scroll is for navigating magnified photos on smartphone displays,” said Dr. David Y. Feinstein, President and CTO of INNOVENTIONS. “Unlike image viewing, PDF viewing is notoriously difficult on mobile phones, always requiring substantial magnification and forcing the user to continuously drag the screen with their finger. We have now refined our proprietary dynamic scrolling algorithms to finally achieve convenient and smooth single-hand scrolling of magnified PDF pages.”

Invented more than 14 years ago by Dr. Feinstein, RotoView is the original Smart Scroll technology for tilt and motion gestures. Since then the company has promoted the idea of combining tilt based scrolling with standard touch screen gestures to enhance the user interface of mobile devices.

The RotoView PDF Reader app is a complete tool for viewing PDF files and includes all of the features expected in a reader app, plus RotoView’s unique navigation tools. It is available now from Google Play for all Android devices. (A one-time $0.99 in-app purchase allows you to save your annotations.)

The similar RotoView Photo Magnifier app is available for both Android and iOS.

The patented RotoView technology and its extensive API protocols for both Android and iOS are available for licensing.
