Live Describe Technology

LiveDescribe is a description software designed, prototyped and developed at The Center for Learning Technology at Ryerson University. LiveDescribe combines the massive power of a television studio with the economy of shareware software. Now the home user as well as the studio professional can add high quality descriptions to virtual any video source.

"Dialog Detection" algorithms work hard to detect appropriate description places so you can concentrate on the highly demanding task creating the best descriptions possible for your video content. Manual description marking allows for the user to define spaces that the detection algorithms don’t pick up. Using LiveDescribe it is possible to reduce description creation time from several hours of work for every hour of described, to nearly a one-to-one ratio. 

The LiveDescribe System

LiveDescribe is designed to allow near real-time DVI to be added to on-line content by DVI describers (the target user group for LiveDescribe). While there are a number of existing software applications such as Softel ADePT (Softtel-USA, 2001) and Magpie (NCAM, 2003) that support post production DVI, they are not designed to support live description for events such as emergency broadcasts, parades, and other events which are often only viewed once, and relevant during the time in which the event occurs. The real-time description process requires a different approach from post-production description. A real-time describer must record descriptive utterances based on a much shorter duration and constrained view of the material where there is no opportunity to fully preview the material before a description is scripted.
