This page describes the RotoView app, a proof-of-concept demonstration and technology evaluation tool for the iPhone, iPad and iPod touch platforms. The app implements a simplified photo viewer for the demonstration, which is limited to Portrait mode operation. Readers who wish to experiment with an actual implementation of the RotoView technology are encouraged to check the free RotoView Photo Magnifier app.
Advanced users, programmers and product engineers can use the RotoView evaluation app to see all the features of the RotoView API in greater depth including Ballistics tables and advanced response graph design. Please review the RotoView White Paper for an introduction to RotoView core technology.

RotoView technology provides one of the most fundamental functions in a smart media device: view navigation. As such, it may be applied for any view appearing on the device, whether it is an image, a table, a web site or a menu. We hope that RotoView will be adopted by the major manufacturers into the operating systems of their devices so that RotoView functionality will be available at every scrollable view object. For the time being, you can test the RotoView functionality on all the photos that are stored in your iPhone or iPod Touch device.
Activating the RotoView app provides a photo selection button following the initial screen. As you can see in our album, we previously saved several photos of maps to demonstrate RotoView in our video. Press Open to choose any photo from your device's albums. Double tap the image or use Pinch touch gesture to further enlarge or reduce the view. RotoView is well adapted to co-exist with and complement multi-touch functions.

After double tapping the photo, the photo is magnified so that only a portion is shown.
The RotoView Scroll Controller Monitor shows the user what portion of the display they are seeing.
Activate RotoView by shaking the device up and down or by tapping the Scroll Controller (marked by a red rectangle outline when RotoView is on). RotoView will now command the view navigation process. Tilt your way in any direction. Notice that you can still perform multi-touch operation in conjunction with the RotoView activity. A unique feature of the RotoView technology is the RotoView Scroll Controller. When activated, the progress monitor shows the view location on the larger virtual image. It also indicates the proportional size of the virtual image in comparison to the screen view. This is particularly useful for large images, long web pages and lengthy text documents or spreadsheets.
To explore RotoView, tap the More button. This will bring you to the Settings, Graph Editor, Ballistics and Help screens, where you can change many settings and even response graphs. (You can always reset the app to its default settings using the 'Setup default', the last line in the setup table.) The RotoView app is an advanced development system that can be used to design various RotoView navigation profiles to be used for different applications. Of course, when you license RotoView for your own application you can provide simple and fully optimized setup selections for your end-users, as demonstrated in our RotoView Photo Magnifier app.
The RotoView app is an advanced development system for designing better navigation profiles.
The RotoView time response graph creates complex view navigation responses that may start with a THROW gesture (coarse navigation) followed by GLIDE (fine navigation).
The Ballistics table captures all sensor and response data of the last RotoView navigation.
The screens above gives you a glimpse on how the RotoView app can be used to design and investigate various response curves and navigation profiles. Please review the RotoView app Features and the Tutorials for more details.
