Orange technology is a newly emerged interdisciplinary research area for integration and innovation of health, happiness, and care technologies. The research scope includes computer science, electrical engineering, biomedical engineering, psychological/physiological science, cognitive science, social science, and dechnology (design + technology). The representative color of orange technology originates from a harmonic fusion of red (representing brightness of health and happiness) and yellow (representing warming care). Instead of emphasizing the relations between environments and humans, as proposed by green technology, the objective of orange technology is to bring more health, happiness, warming care, and more mental wellness to society. 
The idea of Orange Technology was first proposed by Professor Jhing-Fa Wang, at the Department of Electrical Engineering, National Cheng Kung University, Taiwan, 2009 . It calls on worldwide scientists, economists, psychologist, sociologist, engineers, and all the other experts to devote their attention to such a movement: From Green movement to Orange movement. Orange movement not only underscores the importance of the research on humanistic technologies, but also brings more health, happiness, and warm care to human beings eventually.
During the past 200 years, the industrial revolution has caused a considerable effect on human lifestyles. A number of changes occurred  with the rapid growth of the economy and technology, including the information revolution, the second industrial revolution, and biotechnology development. Although such evolution was considerably beneficial to humans, it has caused a number of problems, such as capitalism, utilitarianism, poverty gap, global warming, and an aging population . Because of recent changes, a number of people recognized these crises and appealed for effective solutions, for example, the green movement, which successfully creates awareness of environmental protection and leads to the development of green technology or green computing. However, the green movement does not concentrate on body and mind balance. Therefore, a solution that is feasible for shortening the discrepancy between technology and humanity is of utmost concern. In 1972, the King of Bhutan proposed a new concept that used gross national happiness (GNH)  to describe the standard of living of a country, instead of using gross domestic product (GDP). The GNH has attracted considerable attention because it measured the mental health of people. Similar ideas were also proposed in other works. For example, Andrew Oswald advocated Happiness Economics  by combining economics with other research fields, such as psychology and sociology. Moreover, a book entitled “Well-Being” , which was written by Daniel Kahneman (a Nobel Prize winner in Economic Sciences in 2002) explained the fundamentals of happy psychology. The common objective of those theories is to upgrade the living quality of humans, and to bring more happiness into our daily lives. Recently, the IEEE launched the humanitarian technology challenge (HTC) project  by sponsoring resource-constrained areas to build reliable electricity and medical facilities. Such an action also highlights the importance of humanistic care. Like the HTC project, Intel has supported a center for aging services technologies (CAST) (www.agingtech.org), and its objective is to accelerate development of innovative healthcare technologies. Several academic institutes responded to the trend and subsequently initiated medical care research, such as the “CodeBlue” and “Mercury” projects at Harvard University and “Computers in the Human Interaction Loop” (CHIL) at Carnegie Mellon University. Recent surveys on global healthcare markets and aging population also revealed the same phenomenon. In response to the world trendand inspired by those related concepts , Professor Wang created a new interdiscipline “Orange Technology” for studying and promoting health, happiness, and humanistic care. Orange technology and green technology complement each other well. Green technology focuses on environmental protection, whereas orange technology highlights humanism/humanitarianism. Both plug the gap generated by the opposite side.
- H2O Model: According to the studies , Wang et al. proposed a concept for modeling health, happiness, and warming care. As water is essential to life on earth, Health model, Happiness model, and Offering/Caring/Warming model are abbreviated to H2O, for it symbolizes the essence of body and mind. The following figures show the three models.
Regarding the research fields of Orange Technology, it includes the studies on 1) health technology, 2) happiness technology, and 3) warming care technology. The detailed research fields may include:
- Healthcare and disease treatment for the elderly.
- Healthcare and disease treatment for children.
- Care and disaster relief for striken areas.
- Care for low-income families.
- Care for those with the problems of physiology, psychology, and spirits (i.e., body and mind care).
Orange Technology can even be extended to other areas, such as Orange Economy, Orange Design, Orange Product, and Orange Space, Orange Service, to bring more health, happiness, and warm care to human beings.
