and ER are based on the real world. For example, the structure of a molecule is
visualized and displayed stereoscopically on a screen. In the real world we cannot
see the structure of a molecule. However, visualization technology enables us to
see the structure. This is an example of AR or ER. By comparison, HR is totally
different from the real world. For example, in HW we will not be able to distin-
guish the real world from the virtual world.
One or more coaction fields are introduced in HW. A coaction field is a place
where inhabitants, such as human beings or animals, real or unreal, work or play
together. In a coaction field, the means for communication are provided, includ-
ing spoken and written language, gesture, or an image. When a human participant
discusses something with a computer agent, both the human being and the agent
have to share the means for communication. In order for an interaction to take place
in a coaction field, there needs to be some common knowledge on the given topic
among participants in the same coaction field. For example, in order to talk about
traveling, they each need to have common knowledge on the topic of travel. Different
attributes can be given to coaction fields, such as physical laws or biological laws.
In actual reality, when you throw a ball, the ball falls to the ground according to
the law of gravity. However, a coaction field can be made as a nongravity envi-
ronment if desired. Similarly, in actual reality, a flower grows or wilts with sun-
light according to a biological law. Coaction fields can follow their own rules if
preferred.
HyperReality, the intermingling of actual reality and VR, comprises the fol-
lowing elements: HyperWorld (HW), inhabitants (I), coaction fields (CF), and
visualization (V).

i 1.8.1 Definitions of HyperReality, HyperWorld,
and Inhabitants
HyperReality involves the merging of actual reality with VR. In other words, HR
is a seamless world of actual reality and VR. It is composed of HW, I, CF, and V,
and can be notated (HW, I, CF, V). The seamless world of HW is made up of the
real and the virtual, defined as (RW, VW). It has the following elements:
SCA: Any objects from a natural environment or man-made objects such as
a building that are photographed by camera (coded, transmitted through
the communication links) and reproduced and displayed stereoscopically
by using VR
SCG: Any objects generated by computer graphics (transmitted) and
displayed stereoscopically by using VR
SCV: Any objects recognized by computer vision (transmitted, reproduced by
computer graphics) and displayed stereoscopically by using VR

A virtual world (VW) is notated as (SCA, SCG, SCN). An inhabitant is a real
inhabitant (RI) or an artificial inhabitant (AI). A real inhabitant is a human being,
an animal, or a plant.
