"Tilt-and-Scroll" Technology for Smartphones and Other Handheld Devices
RotoView provides a new, unique way to navigate digital music players, smartphones, PDAs, GPS, digital cameras and other small handheld electronic devices.As these devices gain in popularity, manufacturers and their customers are confronted by increasingly complex navigation schemes. We demand that more and more information (maps, spreadsheets, Web pages) be packed into the tiny displays found on these devices, yet a key problem remains: How can the user easily navigate through a large amount of information using that tiny display?
The RotoView® Solution
The
patented RotoView technology solves this problem by allowing the user to
"tilt" their way around the LCD display. During RotoView's Navigation
mode, the user can navigate a large stored virtual display by simply changing
the orientation at which the device is held. In particular, it allows user to
navigate a large display in all directions. How It Works
RotoView relies on our powerful Non-linear Dynamic Response (NLDR) algorithms for tilt navigation. Using the RotoView technology, the hand-held device is entered into the Navigation mode. During Navigation mode, the user first rotates (tilts) the device to the left and then rotates to the right 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 stored picture. The user can navigate in all directions, depending on how the user tilts the device, thanks to its tilt control accelerometer and NLDR algorithms.

RotoView allows the user to navigate any virtual display just by tilting the device. Tilt navigation reduces the need for pressing switches or using a stylus to navigate the display. |
 |
RotoView's view magnification capabilities allow the user to easily zoom in and zoom out while navigating images. |
While in Navigation mode,
response to the re-orientations of the device may change dynamically. For
example, at the start of the navigation the response is fairly coarse in order
to bring the display to the general area. After few seconds within Navigation
mode, the response automatically becomes more refined, to allow exact placement
of the display. As a result, RotoView's NLDR algorithms
do
not require an exact correlation between orientation changes and actual
navigation of the display, which allows for the use of relatively low cost
coarse sensors to determine the orientation changes. RotoView technology can use hand gestures to activate and exit the Navigation mode (and to perform other commands), thus eliminating the need for mechanical switches in future hand held devices that use a combination of voice command and RotoView navigation.
RotoView Evaluation System
RotoView technology can be easily integrated at the main chip set level of most modern hand-held devices. A minimal sensor, two A/D channels and a software driver are all that are required for mass production implementation.
To convince the major
manufacturers of hand held devices of the merit of RotoView, we have developed
the RotoView Evaluation System (p/n INN-8778), which is now available for $195.
An NDA is not required. The 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 hand-held display, and a
flexible USB cable. Individual RotoView add on modules for popular hand-held
devices are under development and will be
available soon.While it is targeted towards engineers and product line managers wishing to quickly evaluate RotoView technology, it's also perfect for electronics hobbyists, educators and other researchers in the field.
