Subobject Detection through Spatial Relationships on Mobile Phones
We present a novel image classification technique for detecting multiple objects (called subobjects) in a single image. In addition to image classifiers, we apply spatial relationships among the subobjects to verify and to predict locations of detected and undetected subobjects, respectively. By continuously refining the spatial relationships throughout the detection process, even locations of completely occluded exhibits can be determined. Finally, all detected subobjects are labeled and the user can select the object of interest for retrieving corresponding multimedia information. This approach is applied in the context of PhoneGuide, an adaptive museum guidance system for camera-equipped mobile phones.
We show that the recognition of subobjects using spatial relationships is up to 68% faster than related approaches without spatial relationships. Results of a field experiment in a local museum illustrate that unexperienced users reach an average recognition rate for subobjects of 85.6% under realistic conditions.

Video games have been entertaining us for nearly 30 years, ever since Pong was introduced to arcades in the early 1970s. Computer graphics have become much more sophisticated since then, and soon, game graphics will seem all too real. In the next decade, researchers plan to pull graphics out of your television screen or computer display and integrate them into real-world environments. This new technology, called augmented reality, will further blur the line between what's real and what's computer-generated by enhancing what we see, hear, feel and smell.

Augmented reality (AR) is a field of computer research which deals with the combination of real-world and computer-generated data (virtual reality), where computer graphics objects are blended into real footage in real time.
At present, most AR research is concerned with the use of live video imagery which is digitally processed and 'augmented' by the addition of computer-generated graphics. Advanced research includes the use of motion-tracking data, fiducial markers recognition using machine vision, and the construction of controlled environments containing any number of sensors and actuators.

stage.width will return the width of the content on the stage and ignore any empty pixels around the edges. So if you only have a 100 px wide rectangle on stage, your stage.width will be 100.
stage.stageWidth will give you the size of the stage, more like Stage.width in Actionscript 2. Use stage.stageWidth if you’re trying to position elements relative to the stage.
Same goes for stage.height and stage.stageHeight.

senocular.com : News: "Here's an interesting factoid/precaution for you ActionScript developers out there: Did you know that Loader instances use the same LoaderInfo for all loaded content?
Why is this important? Most of the time, it's not. After all, you probably didn't already know this, cared to think about it, or even had any problems because of it. This is because, typically, when you load something in a Loader and then unload it or replace it with something else, you no longer need or interact with the original content you loaded. But what if that content is still used? Then, you might find yourself in for a surprise since Loader.contentLoaderInfo is the same LoaderInfo object each DisplayObject loaded into that Loader uses for it's own loaderInfo despite the originating SWF."

navigateToURL () function
public function navigateToURL(request:URLRequest, window:String = null):void
Language Version: ActionScript 3.0
Runtime Versions: AIR 1.0 Flash Player 9
Opens or replaces a window in the application that contains the Flash Player container (usually a browser). In Adobe AIR, the function opens a URL in the default system web browser
Important Security Note
Developers often pass URL values to the navigateToURL() function that were obtained from external sources such as FlashVars. Attackers may try to manipulate these external sources to perform attacks such as cross-site scripting. Therefore, developers should validate all URLs before passing them to this function.
Good data validation for URLs can mean different things depending on the usage of the URL within the overall application. The most common data validation techniques include validating that the URL is of the appropriate scheme. For instance, unintentionally allowing javascript: URLs may result in cross-site scripting. Validating that the URL is a within your domain can ensure that the SWF file can't be used as an open-redirector by people who conduct phishing attacks. For additional security, you may also choose to validate the path of the URL and to validate that the URL conforms to the RFC guidelines
For example, the following code shows a simple example of performing data validation by denying any URL that does not begin with http:// or https:// and validating that the URL is within your domain name. This example may not be appropriate for all web applications and you should consider whether additional checks against the URL are necessary.

TextField - Flash CS4 Professional ActionScript 3.0 Language Reference
The following example defines two TextField objects. The first TextField object has two associated event handlers. When you click the mouse inside this first text field, the mouseDown event is dispatched, and the associated mouseDownScroll handler is called. The mouseDownScroll() handler causes the field to scroll. Then, the scroll event is dispatched, and the associated scrollHandler() handler updates the second text field to display the current scroll position.

Class public class TextField
Inheritance TextField Inheritance InteractiveObject Inheritance DisplayObject Inheritance EventDispatcher Inheritance Object
Language Version: ActionScript 3.0
Runtime Versions: AIR 1.0 Flash Player 9
The TextField class is used to create display objects for text display and input. All dynamic and input text fields in a SWF file are instances of the TextField class. You can give a text field an instance name in the Property inspector and use the methods and properties of the TextField class to manipulate it with ActionScript. TextField instance names are displayed in the Movie Explorer and in the Insert Target Path dialog box in the Actions panel.
To create a text field dynamically, use the TextField() constructor.
The methods of the TextField class let you set, select, and manipulate text in a dynamic or input text field that you create during authoring or at runtime.
ActionScript provides several ways to format your text at runtime. The TextFormat class lets you set character and paragraph formatting for TextField objects. You can apply Cascading Style Sheets (CSS) styles to text fields by using the TextField.styleSheet property and the StyleSheet class. You can use CSS to style built-in HTML tags, define new formatting tags, or apply styles. You can assign HTML formatted text, which optionally uses CSS styles, directly to a text field. HTML text that you assign to a text field can contain embedded media (movie clips, SWF files, GIF files, PNG files, and JPEG files). The text wraps around the embedded media in the same way that a web browser wraps text around media embedded in an HTML document.
Flash Player supports a subset of HTML tags that you can use to format text. See the list of supported HTML tags in the description of the htmlText property.

ExternalInterface - Flash CS4 Professional ActionScript 3.0 Language Reference
Language Version: ActionScript 3.0
Runtime Versions: Flash Player 9, AIR 1.0
The ExternalInterface class is the External API, an application programming interface that enables straightforward communication between ActionScript and the Flash Player container– for example, an HTML page with JavaScript. Adobe recommends using ExternalInterface for all JavaScript-ActionScript communication.
You can call an ActionScript function in Flash Player, using JavaScript in the HTML page. The ActionScript function can return a value, and JavaScript receives it immediately as the return value of the call.
This functionality replaces the fscommand() method.
From ActionScript, you can do the following on the HTML page:
* Call any JavaScript function.
* Pass any number of arguments, with any names.
* Pass various data types (Boolean, Number, String, and so on).
* Receive a return value from the JavaScript function.
From JavaScript on the HTML page, you can:
* Call an ActionScript function.
* Pass arguments using standard function call notation.
* Return a value to the JavaScript function.
Flash Player does not currently support SWF files embedded within HTML forms.
Note: In Adobe AIR, the ExternalInterface class can be used to communicate between JavaScript in an HTML page loaded in the HTMLLoader control and ActionScript in SWF content embedded in that HTML page.
