Human–Computer Interaction (HCI) is no longer restricted to interaction between
users and computers via keyboard and screen: Currently one of the most challenging
aspects of interactive systems is the integration of the physical and digital aspects of
interaction in a smooth and usable way. The design challenge of such mixed reality
(MR) systems lies in the fluid and harmonious fusion of the physical and digital
worlds. Examples of MR systems include tangible user interfaces, augmented reality,
augmented virtuality and embodied interfaces.
restrictions. AR also doesn't consume as much time and effort in many applications
because it's not required to construct the entire virtual scene, which can be tedious and
In this book, several new and emerging application areas of AR are presented. It is
divided into three sections. The first section contains applications in outdoor and
mobile AR, such as construction, restoration, security, and surveillance. The second
section deals with AR in medical, biological, and human bodies.
Economies of learning refer to decreasing average cost or increasing average
effectiveness, as a result of accumulating experience and know-how. The transition from old
to new processes may well cause the opposite effect; increasing average costs or decreasing
effectiveness as experience is lacking. Thus patients may have CPC detection performed and
regardless of the result proceed to prostate biopsy.
