Smart Blackboard Multi-Touch Technology?

Now let's take a look at the world of multi-touch with XYC editor.

What is multi-touch technology?

In fact, the term multi-touch is not a new term. It has existed in touch screen all-in-ones and several devices since the birth of tablets. However, due to its limited popularity, many netizens are not familiar with it. With the entry of smart blackboards into our campus, the term multi-touch has attracted everyone's attention.

So what is multi-touch?

As the name suggests, multi-touch technology refers to a technology that allows computer users to control the graphical interface through multiple fingers at the same time. How to achieve the process of multi-touch interactive system from quantitative change to qualitative change.

(I) Traditional multi-touch technology

Multi-touch technology is composed of touch devices (such as computer monitors, splicing screens, LCD screens, tables, walls) and touchpads plus PC parts. The behavior of simultaneous multi-touch can be recognized through software or multi-touch writing. This is different from the common touch screens on the market (such as computer touchpads and bank ATMs). The common Intelligent blackboard touch screens on the market can only recognize single or double points.

(II) Application of modern touch technology

The input devices of traditional computers are keyboards and mice, and the output devices are monitors, which are later extended to display terminals. The difference between multi-touch computers and traditional computers is that their input and output are all concentrated on the monitor. You input commands on the monitor, and the computer responds to the results on the monitor. Under the existing technology, the display devices used by multi-touch technology mainly include LCDs, rear projection monitors, etc. Devices such as holographic displays are still in science fiction movies and scientists' laboratories.

(III) Development of touch technology

Multi-touch technology has brought many amazing innovations, which are not limited to multi-touch devices, but also triggered the emergence of more related devices. So far, there are five technologies for building a stable multi-touch platform, namely: Frustrated Total Internal Reflection Multi-Touch Technology (FTTR) pioneered by Professor Jeff Han; Backscattered Light Multi-Touch Technology (Rear-DI) adopted by Microsoft Surface; Laser Planar Multi-Touch Technology (LLP) proposed by Alex Popovich; Infrared Light Emitting Diode Planar Multi-Touch Technology (LED-LP) proposed by Nima Motamedi; Scattered Light Planar Multi-Touch Technology (DSI) proposed by Tim Roth.

(IV) Various components help the imagination of touch technology

In addition to these five mainstream technologies, there are some other technologies that can also build multi-touch devices, including sonicators, capacitors, resistors, motion capture devices, locators, pressure sensing strips, etc. According to data, infrared multi-touch technology is the most used and more mature technical solution in the industry. Usually, these various sensors are combined to build a special multi-touch device.
Many people think that multi-touch is limited to zooming in and out. In fact, zooming in and out is just one of the practical application examples of multi-touch.

With multi-touch technology, the application of smart blackboard can be infinitely expanded through unlimited imagination. Programmers can apply multi-touch to many aspects, and change or innovate more operation methods to a certain extent.

① Playing the piano on hard glass
A typical application is that playing the piano on hard glass becomes a reality. If you turn your mobile phone screen into piano keys, it is still very interesting to coax a little girl.

② Ps simulator
Another typical example is the Ps simulator on Apple mobile phones. Through multi-touch technology, it realizes the combination input of direction keys and other buttons at the same time.

③ Multi-person operation of large-screen games
Multi-touch can also be applied to large-screen games through multi-person operation at the same time, multi-touch all-in-one machines, multi-touch multi-person operation for education and teaching, multi-touch all-in-one machine multi-person operation can be used for conference teaching, and multi-touch all-in-one machine multi-person simultaneous operation can be used for product promotion.
You can also customize the smart blackboard touch application related to it separately.
