Computer-based learning in radiology: a hypermedia application in CT.

Multimedia is a form of computer data presentation that uses multiple formats (text, illustration, sound, and animation) to enhance attention to and retention of presented information. Hypermedia is a nonlinear, branched access version of this that allows the user to pursue information more freely and variably than a linear format does. We used the hypermedia format to create an interactive medical teaching program that we believe holds the user's interest and attention better than a straight-text style does.
