touch screen interactive whiteboard
Apr 26, 2018

In 2015, the shipment of interactive smart tablets surpassed that of projection-type electronic whiteboards for the first time (AVC data show that 99.0 million units of interactive smart tablets were shipped in Q2 2015, and the market share was as high as 50.4%), and the interactive tablet integrated design , With higher resolution, colorful, more resistant to environmental light and other characteristics, in recent years has been the unanimous favor of many educational users. Therefore, this result is also in line with the law of market development, but this does not mean that the projected electronic whiteboard thus "ends." In the future, projection whiteboards and LCD touch whiteboards will still coexist for a long time.

The

First of all, from the perspective of subdivision size, the large-size market is still occupied by a projection electronic whiteboard. In addition, due to the historical accumulation and procurement of funds, the electronic whiteboard has a relatively solid user base and better recognition. Both software content, after-sales service, and market training have unmatched maturity. Popularity, education for the user's very strong display market, it is not easy for an education user to completely abandon the electronic whiteboard and transfer to the flat-panel whiteboard in a short time.

The

Secondly, relying on the mature development system of the projector and its own technology accumulation, the projection electronic whiteboard has now entered the mature and stable stage of development of the technology. In 2015, the projector-type electronic whiteboard introduced a laser projector, which set off a wave of laser projection in the field of education. Under the premise that the brightness, resolution and other conditions of the laser projector fully meet the Chinese classroom environment, the laser projector also provides a wider color gamut, realizes more yuan color performance, and extremely detailed image display capabilities, allowing the potential of large-size electronic whiteboards. To be fully released. In addition, the laser projector is more clear and natural in effect, and can better protect the health of students' vision; at the same time, it also allows the light bulb replacement problems and brightness attenuation problems that have been criticized by the industry to be solved, and it also stimulates the projection electronic whiteboard industry. A new wave of upgrades.

The

On the other hand, flat-panel whiteboards have achieved tremendous development. However, because the core technologies associated with LCDs are in the hands of foreign brands, it is difficult for domestic brands to have the right to speak in the industry. Due to the lack of core technology and the ability to control the components, LCD touches the electronic whiteboard and it is difficult to keep prices down. This is critical for the cost-sensitive education market. In many financially stressed regions and schools, they prefer to choose low-cost electronic whiteboards. They are also reluctant to place expensive tablet devices on high-traffic people and are easily damaged. In the classroom.

The

In a comprehensive view, under the condition that the country strongly supports intelligent teaching and network technology, the projection whiteboard and interactive smart tablet will be increasingly used in the teaching field, and due to their unique advantages, the projection whiteboard and LCD Touching the whiteboard will coexist for a long time in the future.

The

It's too early to talk about "replacement"

The

The interactive tablet (also called crystal touch whiteboard) includes a number of functions of the projector, projection screen, audio, controller, and computer, creating a simple operation for later maintenance. At the same time, it also reduces the energy consumption and also reduces the light pollution, is not affected by external light interference, and does not encounter the situation where the light is darker or the light is not reflected, and the teacher does not have to endure the harsh light. Students will not see black shadows.

The

The multi-touch function of the touch screen display is suitable for various scenes such as recording and live broadcasting, and supports multiple types of media content input sources, including media resources (pictures, animations, videos, etc.) and live video input and output stored on the hard disk ( Live video streaming can be integrated into the anchor system through SDI adapters.) LCD whiteboards are becoming the focus of the market, enriching teaching and other functions, teaching content is more abundant, more humane, and information sharing easier.

The

Interactive smart tablet performance is very prominent, but compared to the traditional electronic whiteboard, but they can not simply define the alternative relationship, although the growth rate of the traditional electronic whiteboard has declined, but in the total sales, the traditional whiteboard still holds the leading The advantage shows that there are still a large number of educational users who still choose the electronic whiteboard.

The

Compared with interactive smart tablets, electronic whiteboards that have been cultivating education markets for 10 years have become more mature in products, production, and after-sales services. For example, in the product design, with the projector's electronic whiteboard, in the light of the principle of self-luminous display compared to the eye's stimulation is smaller, but also contribute to the health of vision; there is a larger product size to better meet the mainstream Classroom needs, and with the further intensification of educational information, traditional electronic whiteboards can also undertake more important tasks such as boosting microteaching, MOOC, and flipping new classroom teaching models. These will all contribute to the long-term stability of traditional electronic whiteboards. development of.

The

In addition, from the summer sales in 2015, it can be seen that the classic combination of whiteboard and short-throw projectors has received large-scale reinforcement of laser projectors, which has once again expanded the advantages of traditional projection-type electronic whiteboards; There is still a long way to go before replacing traditional interactive whiteboards.

The

Internet+ will bring more benefits for education

The

Looking back to 2015, “Internet Plus” is one of the most popular vocabularies. Based on this, many traditional industries are rejuvenated and the education industry is no exception.

The

First, Internet + education makes learning more subtle. Based on the wisdom education cloud platform, information technology such as MOM, micro-curriculum, and flipping classrooms is widely used, and electronic whiteboards, e-schoolbags, and mobile terminals have become common learning tools. Students are more free and autonomous in their choice of content, time, space, and methods. Personalized learning and ubiquitous learning have become the norm.

The

Secondly, Internet+ has played an important role in the education industry and has promoted the rapid updating of educational information methods and resources. On the one hand, for the education industry, the Internet plays a role in the physical distance. Through the use of advanced multimedia teaching equipment through the Internet, even rural classrooms in remote areas can enjoy the teaching of special teachers through micro-classes, etc., and promote exchanges and sharing in different regions, thereby promoting inter-regional, urban and rural areas, and schools. Balanced allocation of educational resources among various types of education; on the other hand, the Internet allows more high-quality teaching resources, policy development information and other content to be publicly and transparently disseminated on the Internet, making it possible to share online communication and teaching and research results.

The

It is easy to see that behind the development, "Internet + education" actually breaks the space barriers and time barriers, and realizes the sharing of educational resources so that students from different regions, or urban and rural schools, can benefit. Here, the fairness of education can also be truly reflected in the process of education informatization.

The

In the era of the Internet+, this profound change in the use of the Internet, big data, and cloud computing to effectively promote educational concepts and educational methods, learning environments, and learning models will become the greatest benefit of the Internet + for education.
