Real-world interface design
Now that the Internet has become widespread and inexpensive computers and sensors are freely available, everyone can easily acquire and manipulate information from all over the world. With conventional computers, we can only manipulate closed information within computers, and with the current Web, we can only access information within computers around the world, but in the near future, a large number of sensors that reflect real-world information will be connected to computers around the world.
In the near future, however, as a large number of sensors reflecting real-world information are connected to computers around the world, it will become possible for anyone, anytime, anywhere to access real-world information from the entire world.
The fact that such "worldwide programming" has become possible is the most significant event since the beginning of human history, and is a major step toward the realization of a truly ubiquitous computing environment.
