Medicuboid

' MediCuboid''' is FullDive technology developed for medical purposes to improve the quality of life of terminally ill patients. It is one of the many innovations that are not based in entertainment.

Background and Developement
The MediCuboid was developed by the government with information provided by Koujiro Rinko. The MediCuboid was not designed as a continuation of the Amusphere but an extension of the NerveGear. The MediCuboid is designed/being developed for commercial use in hospitals but currently is only used to treat patients in terminal care. At the end of Mother's Rosario it is suggested that the information for the MediCuboid was actually provided by Kayaba Akihiko who had gotten Rinko to send it to the developers.

Testing
Yuuki was the first and so far only mentioned tester of the MediCuboid. Her family was asked if they wanted Yuuki to participate in the clinical trials. This proposal bothered the family but Yuuki probably agreed to it because of her expectations of this unknown virtual world

Appearance
The MediCuboid is desribed as a full bed with a white cube shaped helmet covering almost all of the head, leaving only the lips and chin exposed. There is a monitor embedded in the side of the machine which most likely indicates vital signs and above this is a plain logo that says MediCuboid.

Features
The MediCuboid has a stronger electromagnetic output than both the NerveGear and the AmuSphere so it can make muscles completely numb - making it possible to avoid using anesthetics which still have a small but rare risk. It has many more pulse generated components than the NerveGear and it's CPU far surpasses the processing speed of the AmuSphere. These superior specs can enhance the in-game abilities of the user although Asuna does not suspect this is the source of Yuuki's amazing skills.

Known Users

 * Yuuki (deseaced)


 * note: I have decided to remove the other sleeping knights from the list as they most likely did not use the MediCuboid. Kirito mentions in the book that Yuuki's hospital is the only testing area for the MediCuboid and in Chapter 12 of Mother's Rosario Docter Kurahashi says to Shiune that maybe her and the rest can use the MediCuboid next time which suggests that they were not testers.

Trivia

 * At the end of Mother's Rosario Docter Kurahashi tells Asuna that the initial testing is complete and negotiations with the manufacturers are being held about a more practical product.
