Spatial Data Management System, SDMS

Short Definition:

a method for organzing information spatially

Long Definition:

Grew out of an MIT project aimed at ”the creation of an information management system whose distinguishing characteristic is that it exploits the user’s sense of spatiality for purposes of organizing and retrieving data.”

The space is called ‘Dataland’ and includes multiple displays and multidimensional audio.

From the website on The Verge, comes an important criticism:

In “Inventing the Lisa User Interface,” Apple designers Rod Perkins, Dan Keller, and Frank Ludolph explain Dataland was far from a perfect system. “The idea was incredibly simple but placed quite a burden on the user’s memory when the number of documents became large.”

Semantic Zoom

Short Definition:

Means more or less information is shown on demand (such as headings only or abstract) in semantically meaningful ‘jumps’ rather than in smooth visual gradation.

Long Definition:

“Every object visible on the screen has a magnification that depends upon the sequence of portals it is being seen through. As the magnification of an object changes, the user generally finds it useful to see different types of information about that object. For example, when a text document is small on the screen the user may only want to see its title. As the object is magnified, this may be augmented by a short summary or outline. At some point the entire text is revealed. We call this semantic zooming.”
