Sega VR was the virtual-reality headset Sega announced in 1991 as a planned accessory for the Mega Drive, known in North America as the Genesis.
The headset used LCD screens and motion sensors intended to track head movement. Sega promoted it as an immersive gaming product, but the planned consumer version was never released. Reports about motion sickness and technical limitations contributed to its cancellation.
Sega also demonstrated a separate arcade-oriented version, Sega VR-1, in the mid-1990s. This sometimes causes confusion because the unreleased home headset and the later arcade machine shared the Sega VR name.
Sega VR is historically important because it shows that major console makers were experimenting with consumer VR decades before modern systems such as PlayStation VR and Meta Quest.
