Liquidware
Liquidware is a chemical program that is injected into the human system. Liquidware will alter a user's vision, hearing, and other senses to essentially transport them to a different place, or have them experience something other than where they are.
Liquidware is usually interacted with mechanical controls and synchronizes with a computer program to simulate the images and senses of the human. Without external mechanics controlling the liquidware itself, nothing would actually be seen or heard. This is a safety mechanism of the liquidware idea -- so that people would not be locked into altered visions or sound unless it was controlled by themselves.
Programs and uses of liquidware have a mandated "kill switch" that makes it easy to remove the effects of liquidware at any time.
Liquidware is usually used for class activities, games, and other miscellaneous uses.
