Nebraska Scale

In multimedia, a scale developed by the Nebraska Videodisc Design/Production Group to classify the level of interactivity of a multimedia production, videodisc, or other system. The scale runs as follows:

'Level 0'. A system in which productions possess a strictly linear narrative and no interactivity, such as a feature movie.

'Level 1'. A system allowing a small, limited amount of interactivity like basic fast forward and rewind capabilities or some individual frame selection, such as a level 1 videodisc.

'Level 2'. A system utilizing a microprocessor that allows increased interactivity by reading the program from a hard disk or other such storage medium.

'Level 3'. A system utilizing a complete microcomputer, with the storage medium and the drive playing the production as separate entities (such as a CD-ROM drive connected to a personal computer). This allows unlimited interactivity.

'Level 4'. A system in which the drive, operating system, and microprocessor are complete in one unit, the wnetire system being dedicated solely to interactive productions (such as Philips' CD-i).
