Conference Whiteboard Touch Screen Technology Features And Development Trends

The conference whiteboard is a relatively new product. It brings together high-tech products developed by various high-tech means such as cutting-edge electronic technology and software technology. Combined with computers and projectors, it can be directly written with a pen-like an ordinary whiteboard or teaching blackboard. Then input it into the computer. Compared with projectors and ordinary whiteboards, conference whiteboards have their advantages.

Here is the content list:

• The mainstream conference whiteboard touch screen technology

• Other touch technologies are introduced

• The mainstream conference whiteboard touch screen technology

The three methods of infrared radiation, optical and electromagnetic have become the mainstream, and the previous pressure-sensitive whiteboard has withdrawn from the mainstream market. The electromagnetic method is still the first choice for low-cost solutions for conference whiteboards. With projectors, it can be larger than the infrared contrast method; the infrared contrast method can be used with ordinary whiteboards and LCD monitors at the same time, regardless of the display effect or touch. In terms of flexibility, it is better than the electromagnetic method. It is believed that with the further reduction of the cost of the infrared radiation solution, this solution will further become one of the mainstream conference whiteboard touch technology. The optical solution is another solution that will become the mainstream conference whiteboard touch. The advantage is that the cost is lower, especially the larger size, and the hardware cost increases very little, the performance is good, and it will be a strong competitive technology for the infrared cross-radiation scheme.

Other touch technologies are introduced

There are two types of touch screen technology on conference whiteboards, which are more special and unique. We look forward to better development in the future and enriching the field of touch technology. The first is the light-sensing control technology (non-infrared camera solution), the traditional infrared camera positioning technology, the principle is to use the infrared camera to capture the infrared light of the touch screen pen tip to determine the touch position, but the solution that appears in the conference whiteboard can identify non-infrared through ordinary cameras. Touch the object, in other words, the conference whiteboard can directly touch the screen with your finger. The biggest advantage of this solution is that it can form a conference whiteboard touch screen function on any interface, including ordinary walls, liquid crystal displays, etc., and can also support multi-point touch screens, and the cost is not high. The non-infrared camera method is very difficult in software identification and is one of the most anticipated touch screen technologies. The second is the infrared reflective camera solution. This solution is based on the innovation of traditional infrared camera positioning technology. It changes the way that the touch pen head actively emits infrared light to capture. An infrared transmitter is installed on the surface of the conference whiteboard touch screen. The transmitter can the surface of the touch screen is covered with infrared rays that cannot be recognized by the human eye. When a finger touches the screen, the infrared light of the touch point will be reflected and captured by the camera.
