AmuSphere (アミュスフィア, Amyusufia?) is the revised version of the NerveGear which was co-developed by RECTO Progress Inc.. Its successor, temporarily named as AmuSphere 2, is planned to be shown in the 2026 Tokyo Game Show and released to the market in 2027.
The AmuSphere is a helmet that consists of two metal overlapping rings.
The system has been modified to make it safer than its predecessor by changing the microwaves transmitter to a low frequency one and the incorporation of various sensors that continually monitor blood pressure and brain waves and provoke a safety logout feature in case the person's condition becomes abnormal, which includes by default an option that automatically logs out a person if the avatar begins to fall asleep.
In addition to other safety measures, the AmuSphere does not block out signals from the body to the extent of its predecessor, the NerveGear, so some players may rent a specialized room which blocks all external interference, designed to make the experience inside the virtual world all the more real.
As with the NerveGear, it is recommended for the player to get into a comfortable position before beginning to use the device. Once the player has the device worn over the head in a comfortable position, the console can be activated by saying «Link Start».
The Imaginator (イマジェネレイター, Imajenereitā?) is a widely used software on the AmuSphere. The software generates a virtual space for diving where the user may record a message, which can be compressed into mail format and sent to another user. When the receiver plays the file, the sender's recorded virtual body and spoken message would be reproduced. The program also allows conveying video, audio and even the sense of touch.
An incident occurred when a security loop was found in the software. A certain virus infected message would cause a preview of something erotic or gross to be forcefully opened in surround sound and colour when the user dived in with such an infected message in their inbox.
