Since the blackboard slowly faded out of people's vision, the whiteboard has taken over and become the backbone of demonstration equipment such as training. It has been going through the blackboard to the whiteboard for about several decades, and from the whiteboard to the interactive whiteboard. In just a few years. Interactive whiteboard is the trend of whiteboard development. At this stage, interactive whiteboard has become the mainstream and direction.
The components of the interactive whiteboard look simple, but the technical content of the interactive whiteboard has high technical requirements. The interactive whiteboard is composed of electronic hardware such as an electronic sensor whiteboard and a sensor pen, and is equipped with a software service of the whiteboard operating system, which is a complete set of masking equipment. Don't look at such simple components, the technical content is very cash, it needs a combination of computer technology, microelectronics technology, electronic communication technology and other advanced technologies to integrate a modern technology product. Crystals. In terms of performance, the interactive whiteboard is a demonstration device similar to the normal blackboard size, but it needs to realize the intelligent service through the operation of the computer, and achieve the efficient and fast operation experience of human-machine integration. simple.
According to the different hardware skills of whiteboards, interactive whiteboards are mainly divided into two categories: electromagnetic induction hard boards and pressure touch guide soft boards. The working principle of the electromagnetic induction type hard board is to use the electromagnetic induction to position the sensing pen. Therefore, hard-board interactive whiteboards must use some type of sensor pen to walk and draw on the whiteboard. The working principle of the pressure-contact conductive soft board is to use the pressure contact of the fingertip or the nib to make the two layers of the outer surface of the soft board short-circuit at the point to guide the fingertip or the nib. Therefore, the soft board interactive whiteboard can use a fingertip or a pen to draw or manipulate. Although the operating principle is different, the painting, operation and interaction functions of the two types of interactive whiteboards are close, and there are some differences between the hard and soft boards in walking and painting.
The development of whiteboard technology shows that science and technology as a driving force for productivity. In today's fast-changing science and technology, we can more and more enjoy the service and beauty that high-tech products brought by technological development give us. Twenty years ago, people couldn’t think of the blackboard they used to develop into what they are today. This is the surprise that development has brought us.
