Gibson Guitar Corp. is accusing Activision of violating one of their patents with the popular Guitar Hero series of video games. The patent in question is owned by Gibson since 1999 and involves a system that would let a musician “virtually” participate in a pre-recorded concert while wearing a head-mounted 3D display with speakers. The music played on the instrument would then be recorded on a separate track and available for playback with the rest of the tracks to simulate playing in a concert.

Activision’s Guitar Hero does have a similar premise, however it’s played on a “pretend” plastic guitar and is a game where the player tries to mimic notes in concert represented on the monitor by graphical musicians in a concert. Activision is disputing the claim that they infringe upon Gibson’s patent and is asking the federal court to provide an official ruling.

Allegro Rainbow’s Guitar video game has been rocking CES this week. Music Wizard Group’s Guitar Wizard video game is a step forward after their successful Piano Wizard title, but Guitar Wizard is not just another version of Guitar Hero. It’s actually an educational video game that’s designed to help kids of all ages to read and play music.

Guitar Wizard will be available on both PC and MAC platforms, and will come with an actual honest to God guitar from US Music Corp. and an Interface by SoundTech. Plus, the software is compatible with just about any MIDI guitar.
