Microsoft Live Labs researchers have developed Pivot, a tool designed to visually organize large data sets. Pivot presents data in the form of several images accompanied by textual data. Users can zoom into the images to study individual pieces of data, or zoom out to see items grouped according to certain criteria. Data collections can contain a few images with static data attached, or they can be large and connected to a feed of changing data. Pivot is based on Microsoft’s Seadragon, software designed for manipulating large amounts of visual information. Users can make their own collections of data by converting images to the Deep Zoom format used by Seadragon, and annotate them using a format based on extensible markup language. Pivot also could provide a better way to sort through Internet search results, because users could sort through thousands of results visually, instead of just looking a list of the top 10 search results.

Flying pixels have the potential to offer a more immersive three-dimensional (3D) viewing experience than 3D television sets, according to engineers at the Massachusetts Institute of Technology (MIT). The engineers describe their unique 3D display, called Flyfire, as a flock of tiny aircraft carrying multicolored light-emitting diodes (LEDs). The pixels can hover in front of a viewer and form an image, but they also can change their position to add greater depth to the image. “It’s a 3D display with a dual aspect–it can show an image like a traditional display, but then those pixels can move and transform into another shape,” says MIT’s E. Roon Kang. The initial proof-of-principle experiments used quad-rotor helicopters more than 10 centimeters across, and the precise control of their altitude was within three centimeters. Kang says it could take at least five years to make a display with 1,000 or more of the small flying pixels. MIT’s Emilio Frazzoli says onboard controls and a central control system also will be needed to coordinate pixel movement.
