Optical touch technology is a new technology that is different from the existing infrared, surface acoustic wave, resistance, capacitance and other touch technologies. The optical sensor responds quickly to detailed actions, making your application lighter, smoother and more accurate! The creative application of multi-touch technology is the icing on the cake for optical touch technology!
CCD optical touch technology breaks the bottleneck of the original touch technology, greatly improving the accuracy, response speed and life span. The two CCD cameras installed at the left and right corners of the top can accurately detect the positions of multiple fingers. Not only can you click, drag, but also rotate and enlarge the picture freely. These operations depend on the number of fingers and the unit area. Gently touch the screen and enjoy the fun of controlling the movement of three-dimensional objects and zero-distance contact with the virtual animals on the screen.
With the rapid development of modern computer technology, touch screens have been used more and more widely. With its strong technical strength, Shuangqi has integrated a variety of advanced large-format flat-panel touch technologies at home and abroad, and launched a public communication touch system and a handwriting conference system. It is widely used in media, advertising, inquiry, education, hand-painting, training, conference, command, etc.
Main technical features of CCD optical touch screen:
The multi-touch interactive large screen can be realized in various forms. The interactive large screen uses advanced computer vision technology to obtain and recognize the position of the finger on the screen, and convert the physical coordinates of the finger on the screen into the logic of the computer screen through a specific algorithm Coordinates and control instructions, realize the control functions of the finger or finger on the large screen, such as touching and marking. Achieve natural human-computer interaction and get rid of the limitation of small size on the touch screen. You can also achieve the effect of interactive touch by making an interactive film source, through a large-screen touch frame, etc.
1. Support multi-touch and double writing;
2. It is suitable for LCD, plasma, LED and other displays, projectors (front projection, rear projection), etc. The size can be supported from 15 inches to 250 inches;
3. With multi-screen interactive function, one computer can connect up to 4 touch screens;
4. Driver-free, the touch screen can be used directly after connecting with the PC host, no driver is required, and it can still be used normally after changing a different computer.
Optical touch screen market prospects
It has been more than ten years since China’s touch screen market began to rise in the late 1990s. Touch technologies are also emerging one after another, and the characteristics of various touch screens are also mixed. The current mainstream touch technologies in the domestic market should be infrared, surface acoustic wave and resistive screens. However, these technologies also have flaws, such as sonic screens that require force to click, and the performance of resistive screens is unstable. The emergence of optical touch screens has basically solved the problems of many touch screens, and has sufficient conditions to lead the future touch market.
First, the optical touch technology is superior to the existing technology in terms of response speed and touch accuracy. Among many existing touch technologies, infrared technology is superior to other technologies in response speed, sensitivity, and touch strength, while it is slightly inferior to optical technology.
Secondly, in terms of size, the optical touch screen can be more than 250 inches, and the production cost will not increase significantly as the size increases. Compared with other technologies, the larger the size, the more obvious the price advantage.
The most important point is that from the perspective of IT industry development trends, Microsoft’s future new version of the operating system will vigorously support the use of touch technology, and intends to civilianize touch technology. Including some of the operating system’s accompanying application software, such as touch handwriting pad, two-point touch and so on.
All in all, the installation of a digital signage system mainly depends on execution, and only those manufacturers who always pay attention to their customers will ultimately win. Through the continuous innovation of the digital signage system, the brand will continue to be improved, and the continuous attention to new technologies will achieve good returns.
