She detailed the idea of calm technology, the creation of a digital interface that is invisible, where the real world is the screen and a person's actions are the buttons. People can choose the kind of information that's presented in the real world, creating an annotated reality.

The devices include everything from Schwartz's fishnet vest adorned with connected components, to laptops-in-fanny-packs, to thick glasses that reflect a video display in one lens. The glasses provide a dominant vision of the real world that is overlaid by information from an electronic world. Such information overlays are called annotated reality, a subcategory of wearable computing distantly related to virtual reality.

My readers often tell me that if any version of Enhanced, Augmented,or Annotated Reality gets implemented, it might be abused by people trying to manipulate other people's views and force perceptions upon them.
