Innoventions has developed a technology that expands the small screens found on PDAs and mobile phones.

The Houston-based company said Wednesday that it is shipping a development system for its RotoView technology, which allows PDA and cell phone users to see more of their display by changing the orientation of the device.

The RotoView technology includes a Navigation mode where the user tilts the unit left-right or up-down to see beyond the boundaries of the display. At any time, the user can exit Navigation mode to fix the display (the Fixed mode), then resume Navigation mode and continue to rotate the device to view the remainder of the screen.

"We demand that PDA and cell phone manufacturers pack more and more information into those tiny displays. Yet a critical problem remains: Navigating through a large amount of information, whether it's a map or spreadsheet, is awkward," said David Y. Feinstein, president of Innoventions. "The RotoView Development System is a way for OEM manufacturers, product managers and researchers to easily try out the RotoView technology and explore ways to best implement it."

The $195 RotoView Development System includes a fully assembled board for the RotoView sensor module, a Windows-based software package that allows you to interface the module to your PC and emulate the handheld display, and a flexible USB cable. The company said a RotoView add-on module for the Pocket PC will be available soon.
