Interactive video

In 1962, Steve Russell, a student at the Massachusetts Institute of Technology (MIT), created Spacewar!, the world's first interactive computer game.

[2] While watching this film, the audience in the cinema theatre would choose one of two scenes during the plot fork.

[4] In 1983, Sega released Astron Belt, the first interactive arcade game on LD.

These hotspots allow the viewer to learn more about a particular object, product, or person in the video.

The object or space is depicted using video loops, not still, creating a more "live" feel.

Instead of 3D computer graphics an interactive image flow is created using premade video clips, often produced by overlaying computer-generated material with 12-inch videodisc images (where the setup is known as "level III" interactive video, to distinguish it from "level I" or videodisc-only, and "level II" requiring specially made videodisc players that support handheld-remote-based interactivity without using an external computer setup).

In 2008 YouTube added Video Annotations as an interactive layer of clickable speech-bubble, text-boxes and spotlights.

[23][24] Contemporary interactive video artists like Miroslaw Rogala, Greyworld, Raymond Salvatore Harmon, Lee Wells, Camille Utterback, Scott Snibbe, and Alex Horn have extended the form of interactive video through the dialog of gesture and the participatory involvement of both active and passive viewers.

This involves the user/operator to mix video clips, runtime plugins, and FX to the music's mood, bpm, and vibe.
