The optical touch technology, abbreviated as CCD, is a new technology that is different from the existing infrared, surface acoustic wave, resistance, and capacitance touch technologies. The optical sensor responds quickly to detailed actions, making your application lighter, smoother, and more accurate! The optical touch IFP can be used in conference venues, commercial exhibition venues, education and training venues, exhibitions, financial industry, and military industries; creative multi-touch technology applications are even more important for optical touch technology! Optical touch technology has broken the bottleneck of the original touch technology and has greatly improved accuracy, response speed, and life. The two CCD cameras installed at the top left and right corners can accurately detect the positions of your multiple fingers, allowing you to not only click, drag, but also freely rotate and enlarge the picture. These operations depend on the number and unit of your fingers. area. You can also enjoy the pleasure of controlling the movement of three-dimensional objects and the zero-distance contact with the virtual animals in the screen by gently touching the screen.
The LED light at the top left corner emits light and is reflected by the surrounding reflectors and enters the CCD camera in the top right corner. Similarly, the light from the top right LED lamp is transmitted to the left CCD camera. The dense light is in the touch area. A light net is formed inside. When the touch point enters the light network, the emitted light and the received light of the point form an included angle, and at the same time, the CCD camera at both ends and the lines formed between the two lights and the two cameras form two included angles. The coordinates of this point are accurately entered by the controller, which is the same as the principle of realizing multi-touch!
1. Suitable for LCD, plasma, LED and other displays, projectors (front and rear), 15-250 inch can support;
2. With multi-screen interactive features, a computer can connect up to 4 touch screens;
3 driver-free, touch screen and PC host can be used directly after connection, without the need to install the driver, after replacing a different computer can still be used normally.
The touch screen market in China has been more than a decade since its inception in the late 1990s. The touch technology is also emerging in an endless stream. The features of various touch screens are also mixed. The current domestic market, but these technologies also have flaws, such as sound waves. Screen clicks require strength, resistive screen performance is unstable and so on. The appearance of the optical touch screen basically solves the problems of many touch screens and has sufficient conditions to lead the future touch market.
Optical touch technology is superior to the prior art in terms of reaction speed and touch accuracy. Among many existing touch technologies, infrared technology is superior to other technologies in its response speed, sensitivity, and touch strength. However, it is slightly inferior to optical technologies. Secondly, optical touch screens can be over 250 inches in size. Moreover, the increase in size does not increase the production cost significantly. Relative to other technologies, the larger the size, the more obvious the price advantage;
The most important point is that from the IT industry development trend, Microsoft's new operating system in the future will strongly support the use of touch technology, and intends to use touch technology for civilian use. Including some of the operating system with the application software, such as touch pen tablet, two touch and so on.
The innovation of digital signage technology, through the innovation of software and hardware technology, can provide detailed content introduction, and bring direct influence to customers at the right time and at the right place. For example: if the screen is placed next to the product display, or in the restaurant, the customer orders directly by placing on the dining table screen or advertising in the customer waiting area. In addition, personalized play services such as customized personalized experience services and interactive touch screen information distribution for outdoor large-scale event broadcasting and shelf display are also the current trend of digital signage development.
Targeting the target audience is a common problem faced by the market today, including: when, where and with whom consumers consume; consumer experience of consumers; target consumer market size; separate advertising costs from television, radio, and posters, etc. Compared with the digital signage system, traditional posters have the disadvantages of long time periods, high prices, lack of interest and dynamics, and long planning and production cycles. The old digital signage model that we have seen is simply a combination of related products such as computers, screens, and audio. It is difficult to achieve good integration effects in various parts and there are many connections. The content is often updated by playing DVDs and CDs. Current digital signage models include: LCD or Plasma digital display screens, professional media players, content management software, file content, and networks. In terms of content, in addition to the ever-increasing demand for animation content, the functional requirements for digital signage are also increasing. For example, the customer's requirements for the speed and access interface of the digital signage system are constantly rising, requiring immediate response and good after-sales service.
