A New Autostereoscopic Display Technology: The SynthaGram

StereoGraphics Corporation has introduced a new flat-panel autostereoscopic display, the SynthaGram. It produces bright, clear, and satisfying three-dimensional images that may be viewed from a substantial angle of view by many observers. A progression of perspective views, like that used by the parallax panoramagram, is created either by computer or photographic means. Each view is sampled at the sub-pixel level and mapped by means of a process called Interzigging. The resultant Interzigged image is a sub-pixel map of spatial information. The map is displayed on a flat panel screen-- in the present case a liquid crystal display. A lenticular screen overlays the flat-panel display, but the direction of the lenticule boundaries are angled to the vertical. The technology, we believe, is the basis for electronic autostereoscopic display solutions for many applications

Riders have spoken: replaying and archiving pervasive performances

In this paper we present a practical study that formed part of the larger Creator project 1. Data, such as GPS trails, video and audio files from a pervasive-performance were used to explore multidisciplinary understandings of such 'ephemeral' pieces. Video and audio content tagging was also explored as a device to aid in developing the archive for replay. It is recommended that projects involving artistic practice should make documentation and subsequent archiving part of their overall research strategy. ©2010 ISAST
