AmuSphere (アミュスフィア, Amyusufia?) is a second generation FullDive console, co-developed by RECT Progress Inc., that is the successor to the NerveGear. 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 microwave transmitter to a low frequency one and the incorporation of various sensors that continually monitor blood pressure and brain waves. If the person's condition becomes abnormal, a safety logout is provoked. This, by default, includes an option that automatically logs out a person if the avatar begins to fall asleep. Unlike the NerveGear, the AmuSphere is not equipped with an internal battery..
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 realistic.
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.
- The AmuSphere has a feature of automatically disconnecting the user if anyone from a special list of important people (e.g. family members) or emergency services (e.g. the police, the hospital) calls them.
