Imagine Multimedia Inc, the Ann Arbor, Michigan-based spin-off of the University of Michigan and creator of MediaStation, has developed InterActive Author, a hypermedia program for authoring interactive applications. Imagine says it has taken the complexity out of authoring by creating a program that constructs complex hypermedia applications without recourse to a scripting language. It can be combined with MediaStation for media acquisition, editing and management. Together they support multiple authors working on different aspects of an application simultaneously over a network. InterActive Author, whose price is still unfixed, will be available on NeXT Computer Inc machines in the third quarter, with an X Window version coming by the end of the year. An X Window version of MediaStation will ship on DECstation 5000s this summer.
