What the user sees with 4Dtext
The user sees a piece of text, just like normal, flat text - but the information that he wants is waiting under the text.
Mouse gestures (click and hover) provoke the underlying information to be seen and to be heard. It can be more text, images, sound, video, a map, or an arbitrary Flash recording.
In turn, the user can ask a new layer for more information. There are flexible methods to control the pop-up windows. Most users will be happy with just a few windows open.
The user can login to customize his experience on a website. His profile determines what kind of information he sees. This can vary with each session, each webpage or for the user.
What the user sees is a combination of what the user wants, what the website designer provides, and what is available in the 4D-databases AND from Semantic web services on the Internet. All under the control of the designer to optimize the user experience.
The user's experience adapts to his past usage. If he was never interested in, for example, a word's etymology, that choice slides into the background. It's always available -- it just doesn't get in the way of more commonly-used information.
