Smart Scroll Technology for Smartphones and Other Handheld Devices

RotoView pioneered "tilt-and-scroll" display navigation for smartphones, tablets, GPS, 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, 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 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 stored virtual display by changing the device's orientation or with various movements. In particular, it allows user to quickly and efficiently navigate a large display in all directions. Similarly, it can control the changing background view of a game application based upon tilt and movements.

RotoView complements touch screens

RotoView tilt-based browsers can perform all view navigation functions in modern personal media devices and it works particularly well with touch screen devices, as demonstrated in the following presentation. RotoView smart scrolling works together with touchscreen drag commands. It is particularly useful when the user prefers to navigate with only one hand. Using RotoView, the user avoids the problem of inadvetrent touches on links scattered on the screen that will take the view elsewhere.

How It Works

RotoView uses the data from a built-in gyroscope (or other forms of orientation and movement sensors) to control the view navigation of a smart media device. To navigate, the hand-held device is entered into the Navigation mode where the user rotate (tilt) the device to the left and then rotate to the right to see beyond the boundaries of the display. The user can navigate in all directions, depending upon how the user tilts or moves the device. The amount of scrolling is based upon our powerful Non-linear Dynamic Response (NLDR) algorithms which do not require an exact correlation between orientation changes and the actual navigation of the display. Once the desired scrolling is achieved, the user can exit Navigation mode to fix the display (the Fixed mode).

While in Navigation mode, RotoView's Dynamic Scroll protocol response to the re-orientations of the device may change dynamically. Typically, the Dynamic Scroll protocol first perform the THROW gesture, during which the screen scrolls very rapidly in response to small rotations. 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 is automatically followed with the GLIDE gesture during which the scrolling is slower to allow exact placement of the display.

RotoView protocol also offers the Proportional Scroll mode, where the scrolling relates directly to the rotation of the device. Proportional Scroll mode is automatically selected if the screen magnification is relatively small, so that the device rotations can be kept small to avoid oblique angle viewing.

RotoView technology can use hand gestures to activate and exit the Navigation mode, thus eliminating the need for mechanical switches or two hand operation with touchscreen commands. 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 Proof-of-Concept App

RotoView technology can be easily integrated with all current smartphones and modern personal media devices that already include a tri-axis accelerometer or gyroscopes. To demonstrate the importance and benefits of the RotoView patents and technology, we have created a RotoView proof-of-concept app which is available as a free app. It is also a useful productivity tool for your iPhone, providing unique view navigation for your stored pictures.

Although RotoView provides the fundamental function of view navigation which is relevant to every scrollable view (web, page, game, photo, etc.), the RotoView app is currently able to navigate only the photos stored in your smartphone. Once our technology is adapted by all smartphone's OS, RotoView navigation will be fully integrated with web browsing and with any program that utilizes scrollable contents views.

The RotoView app follows 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.

"Some ideas are so simple, when you first hear of them you think, 'Now why didn't I think of that?' RotoView is one such invention."
Brighthand.com, August 2003

"Here's a technology that could put a new spin on moving and shaking... Don't be surprised if you see people waving their PDAs around."
PC Magazine, September 2003

"Everyone is on the move. And a Houston, Texas-based firm believes it has the tilt-to-navigate technology that manufacturers need to enable products for the PDA and smart phone market. They’ve actually had the technology for some time – but the market and the pricing are finally coming together to make a better business case for their tilt-to-navigate technology."
