"Tilt-and-Scroll" Technology
for Smartphones and Other Handheld Devices
RotoView provides a new, unique way to navigate
smartphones, digital music players, GPS, gaming devices, PDAs, 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. Users demand that more and more information (maps, spreadsheets, web pages, action games) 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? Better yet, how can we do it intuitively, and preferably, with a single hand?
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. Similarly, it can control the
changing background view of a game application based upon tilt and
movements.How It Works
RotoView introduces the concept of Response Curve which controls the amount of display navigation based on the sensor data. It produces intuitive overall view navigation based upon our powerful Non-linear Dynamic Response (NLDR) algorithms. Using the RotoView technology, the hand-held device is entered into the Navigation mode. During Navigation mode, the user may rotate (tilt) the device to the left and then rotate 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 or moves the device, thanks to its tilt control accelerometer and NLDR algorithms. It can also incorporate a magnetic compass or other sensors to detect directional changes.

RotoView allows the user to navigate any virtual display by tilting the device. Tilt navigation reduces the need for using buttons or touch screens and allows the user to navigate with just one hand. |

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. It should be noted that most of the smartphones and other hand-held devices manufactured these days already include such hardware and the basic software driver.
To convince the major
manufacturers of hand held devices of the merit of RotoView, we have developed
several years ago the RotoView Evaluation System (p/n INN-8778), which is
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. Response curves developed by this
evaluation system can be easily ported to the user's actual hand held
application using the device SDK provided by the manufacturers.While it is targeted towards engineers and product line managers wishing to quickly evaluate RotoView's patented technology, it's also perfect for electronics hobbyists, educators and other researchers in the field.
