Smart Scroll Technology for Smartphones and Other Handheld Devices

RotoView pioneered "tilt-to-scroll" display navigation for smartphones, tablets, smart watches, GPS maps, gaming devices, wearable virtual reality (VR) devices, digital cameras, eBook readers, and other small handheld electronic devices. As these devices become even more popular, manufacturers and their customers are confronted by increasingly complex navigation schemes. Users demand that more and more information (maps, images, videos, 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 navigate that small screen 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 display. During RotoView's Navigation mode, the user can navigate a large virtual display by changing the device's orientation or with various movements. In particular, it allows the user to quickly and efficiently navigate a large display in all directions. With RotoView, the user avoids smearing the display with fingerprints and it eliminates the problem of inadvertent touches on links scattered on the screen that will take the user elsewhere.

RotoView Complements Touch Screens

While RotoView tilt-based scrolling can perform all view navigation functions and even replace touch screen in some applications, it is designed to be well integrated with the touch screen navigation available in most modern media devices. RotoView scrolling works together and complements touchscreen drag commands, as demonstrated in the following presentation.

How It Works

RotoView uses the data from a built-in gyroscope (or other sensors) to control the scrolling of a smart media device. To navigate, the hand-held device is entered into the Navigation mode where the user rotates (tilts) the device in the direction where the screen need to be scrolled. Once the desired scrolling is achieved, the user can exit Navigation mode to fix the display (the Fixed mode).

The amount of scrolling in response to tilt changes is based upon the active RotoView scrolling modes, including the Proportional and Dynamic Scroll modes. During the Proportional Scroll mode, the scrolling amount directly relates to the device's tilt. Proportional Scroll mode is automatically selected if the screen magnification is relatively small, so that the device's tilts can be kept small to avoid oblique angle viewing. Proportional Scroll mode may also be used when viewing 360-degree panorama photos, where a 360-degree rotation is correlated with a full circle scrolling of the panoramic photo.

During Dynamic Scroll mode, the scrolling speed is related to the tilt changes of the device. The Dynamic Scroll mode may be automatically selected with highly magnified views, so that the screen relative rotation returns to the initial holding angle at the end of the scrolling process. This insures an optimal viewing angle. The speed of scrolling is based upon our powerful Non-linear Dynamic Response (NLDR) algorithms which can work with low cost and less precise rotation sensors.

While in Navigation mode, RotoView's scrolling response to the re-orientations of the device may change dynamically. Typically, the Dynamic Scroll protocol first performs the THROW gesture, during which the screen scrolls very rapidly in response to small tilts. As a result, the user can quickly reach all areas of the contents view without having to look at the screen at uncomfortable oblique angles. The THROW gesture may be automatically followed with the GLIDE gesture during which the scrolling is slower to allow exact placement of the display.

The RotoView technology offers an optional Scroll Controller that make scrolling guidance easier compared to the tradional scroll bars. The Scroll Controller provides a transparent, interactive map that shows the portion of the contents view that is currently displayed on the screen.

RotoView technology can use intuitive hand gestures or touch screen commands to activate and exit the Navigation mode. The Navigation mode can be automatically terminated if the user holds the device steady without any rotation for a period exceeding the preset inactivity time.

RotoView technology can be easily integrated with all current smartphones and modern personal media devices that already include a tri-axis accelerometer and/or gyroscope. To demonstrate the importance and benefits of the RotoView patents and technology, we have created several proof-of-concept apps, including the RotoView Photo Viewer for Android and RotoView Demo for iPhone. These RotoView Photo Viewers are useful productivity tool for your phone, providing unique view navigation for your stored pictures. The new RotoView PDF Reader for Android allows you to navigate your PDF pages.

The fundamental function of scrolling provided by the RotoView technology is clearly relevant to every scrollable view (web, video, text, page, game, photo, etc.). We included many optional features in the RotoView apps. Some features may be ommitted in specific applications (for example, use RotoView with standard scroll bars without the Scroll Controller). Once our technology is adapted by all smartphone's OS, RotoView navigation will be fully integrated and customized with web browsing and with any app that utilizes scrollable contents views.

The RotoView apps follow our earlier RotoView PC Evaluation System (p/n INN-8778) which was deployed in 2003 to convince manufacturers to adapt our technology. The new RotoView app will enable you to evaluate the technology and the advanced know-how accumulated by INNOVENTIONS.

The RotoView Patent

"If sliding our fingers up and down our phones feels like an intuitive scrolling motion today, simply tilting our screens may be the obvious choice of tomorrow when it comes to moving text around a screen. Thanks to a new patent awarded to Houston-based Innoventions Inc., reading an article may soon be as easy as changing your viewing angle."
