On Friday, February 28, April 15, Beijing Control jetstone demonstrated their latest product, Yutong.

ASIDE: input devices have been one of the hot topics of brain storm during lunch in our R & D department for a long time, becauseProgramEmployees are dealing with the keyboard all day long, especially programmers in Unix. No mouse support is provided for both VI and Emacs on the terminal, we are very concerned about what input devices can achieve higher productivity. After hearing that someone has invented the pedal to replace ALT in Emacs, our developers' thinking is further divergent on this basis. Later, it is recognized that the instrument is very promising to replace the keyboard into the next generation of new favor for programmers. Hehe, you can imagine using USB to connect to a guitar or an accordion for chatting.

the principle of Yutong pen is simple: the entire device is divided into two parts, A base for transmitting an ultrasonic wave is connected to the host via USB, and a trajectory in a nearby specially crafted pen motion is obtained. The actual coordinates are calculated and returned to the driver to generate a bitmap ; in essence, it is another type of tablet, but it becomes a wireless method. In this way, any computer immediately becomes a tablet PC after such a peripherals exist! Of course, some tablet OS built-in applications such as electronic ink are still lacking. In order to make the demo look more convincing, jetstone employee's notebook screen is covered by a transparent film. During the demonstration, a rectangular area is set on the screen, then, write and draw in this area, which looks exactly the same as tablet PC. The Yu Tong pen can also contain a real pen core, so that you can write a sketch on the White Paper, and then copy a copy on the computer; or bigger, make a whiteboard pen, in this way, you can easily obtain all the blackboard books... it is much lower than the traditional electronic whiteboard.
