Como infraestrutura de informatização educacional, os equipamentos de hardware têm recebido maior atenção das escolas. Segundo as estatísticas, nos últimos cinco anos, o hardware de informatização educacional foi o tipo mais comprado pelas escolas.
This is the opportunity for the rapid development of interactive whiteboards and interactive touch screens. The interactive whiteboard has reached a peak of development in China around 2010, and the interactive touch screen has entered the market as a latecomer.
Data from Futuresource Consulting shows that in 2015, the education market has become the largest category in the interactive large screen (including interactive whiteboard and interactive touch screen) market.
Take the United States, one of the countries with the best education quality, as an example. Due to the implementation of the Common Core Standards, schools' investment in educational equipment has increased significantly. This has also directly contributed to the rapid increase in the use of interactive large screens in American classrooms. About 60 percent of American classrooms have been equipped with interactive large screen devices, with a total of approximately 2.1 million units. By 2019, this ratio is expected to reach 71 percent .
From the functional point of view, the interactive whiteboard realizes the interactive control with the computer, which can conveniently present, process and store various digital teaching materials, enrich the teaching content, and can save and operate at any time, which is convenient for reapplication and after-school review.
Comparado com o quadro interativo, a tela de toque interativa oferece uma experiência de usuário mais notável. Ele não apenas suporta as funções do quadro interativo, mas também possui melhores efeitos de exibição e interação, experiência de toque e conveniência de instalação e operação. E há vantagens mais óbvias nos custos de manutenção.
From 2013 to 2016, the global compound annual growth rate of interactive touch screens reached 59 percent ; as of the end of 2016, its share of the interactive large screen market reached 68 percent . In the foreseeable future, this growth trend will continue, and more and more end consumers are gradually replacing interactive whiteboards and projectors with interactive touch screens.
Ease of use becomes the key to interactive large screen, use "gestures" to call up virtual tools
The technology used in large touch screens is not much different from ordinary tablets. Infrared technology and capacitive touch technology are currently the two most mainstream touch technologies on interactive touch screens.
It's just that compared with ordinary tablets, the visibility problems of large-size screens will be more prominent, and the stability of the calibration will also be higher, and considering the long-term continuous use in teaching, the commercial level is usually adopted. Of the panel.
In fact, compared to hardware, the ease of use of software is more prominent in actual use. Many experts in the education industry have also pointed out this problem many times. In addition to the user's experience, ease of use will also affect the manufacturer's user training, which is another threshold for the promotion of interactive touch screens.
For users:
"Reliability and ease of use may be more important than other additional features."
"The first element for any technology to be implemented is its ease of use."
At present, mainstream hardware manufacturers in the market choose to independently research and develop supporting software solutions, such as BenQ, Boxlight, etc.
EZwrite
O software pré-{0}}instalado da tela de toque interativa BenQ-EZWrite permite que os usuários alternem a tela de toque para o modo de quadro branco com uma tecla e convertam o texto, números e tabelas escritos pelo usuário em digital formato, que pode realizar cálculos matemáticos e fórmulas geométricas. E outras operações; em alguns modos, você pode abrir a caixa de ferramentas flutuante, permitindo que os usuários usem ferramentas comuns, como borracha, vídeo e impressão. Além disso, a caixa de ferramentas multifuncional fornecida pela barra de menus contém ferramentas como calculadora, campainha, placar e desenho.
No entanto, todos os softwares atualmente no mercado não conseguiram abandonar a configuração da barra de ferramentas, o que leva ao fato de que, em uso, os usuários precisam alternar para a barra de ferramentas com frequência para encontrar as funções necessárias, e até muitas operações precisam entre no menu secundário ou terciário para completar, para que a experiência do usuário se torne muito turbulenta.
The manufacturers are also aware of this, so they tried to add a lot of gestures to the software, such as using the palm to complete the eraser function, and long pressing the screen with two fingers to call up the corresponding function bar. Although this solves some ease-of-use problems, it also increases the memory difficulty for users. Just like the gesture operation of a mobile phone, the gestures that users can remember and often use are extremely limited, and the definition of each gesture is different between different manufacturers. As a result, once users need to switch platforms, they must re-adapt to a new set of gestures. Mode of operation.
In fact, if you want to solve this problem, it may be more effective to use another way of thinking, which is to allow users to use gestures that are commonly used in life, instead of re-making a set of rules. For example, how to use the ruler in life, then use the same gesture on the touch screen to call up the virtual "ruler" tool.
Qeexo Qishou is the developer of this program.
As a software solution launched by Qeexo Qishou for tablets and large and medium-sized touch screen devices, TouchTools allows users to no longer switch between different functions through the toolbar, but to easily simulate real life on the touch screen. This kind of action is used to complete the corresponding operation, which greatly reduces the user's threshold for use.
Não há dúvida de que as telas sensíveis ao toque acabarão sendo popularizadas em todas as salas de aula. Não haverá apenas um ou dois fabricantes de telas sensíveis ao toque neste enorme mercado. Como solução de software para todas as plataformas, o TouchTools pode ser integrado a diversos softwares de fabricantes, melhorando muito a facilidade de uso dos equipamentos e ainda melhorando a versatilidade entre os equipamentos.
Large and small screens interact to extend the educational scene and enhance classroom participation
There are already many teaching cases using interactive touch screens in European and American schools, and even in elementary schools, kindergartens and preschools, interactive touch screens have been used.
In the Pomona Unified School District, a public school in the United States, teachers tried to use Smart technology's interactive touch screen to teach. You can see that teachers use these devices to teach students to write, learn new words, and train them to learn. The enthusiasm of the students will increase the participation in the classroom. And because of the use of this highly interactive platform for teaching, the collaboration between teachers has also been greatly enhanced.
It is not only Pomona Unified School District, but feedback from many schools has shown that the large screen has a positive impact on classroom participation, and it can even play a role in enhancing students' self-confidence and expression skills.
"Earlier this year, SMARTTechnologies commissioned a study of 400 teachers, school administrators and IT professionals from 26 countries. The results showed that large-scale interactive displays significantly improved student performance. The test results of each subject in the technical class improved by an average of 16 percent , especially in math and English subjects, with an increase of 34 percent ."
---Survey results from manufacturers
Finally, we need to mention another development trend worth noting, that is, the interaction between the large and small screens between teachers and students-the interaction between the large screen used by the teacher and the small screen used by the students, such as writing the teacher's blackboard and explaining The content, shared with students, will greatly extend the current inherent educational scene, and it is also one of the focuses of mainstream manufacturers.
Of course, for the Chinese education market, it may take some time to get to this point, but I believe that with the increase of state investment and capital attention, this process will only get faster and faster.
