What is a multi touch interactive large screen

A large touch screen that can be clicked by several people at the same time, hehe.

Multi-touch screen, using two or more points of different situation media to touch the screen surface, can be perfect to achieve a variety of multi-touch applications such as zoom and rotation. At the same time, it has all the functions and advantages of a traditional single-point infrared touch screen. Different from the traditional single-point touch screen, the biggest feature of the multi-touch screen is that it can operate the content of the screen with two hands, multiple fingers, or even multiple people at the same time, which is more convenient and humanized.

Multi-touch technology is also called multi-touch technology.

Multi-touch is divided into two levels in practical applications:

That. First, the main control chip can collect multi-point signals at the same time.

Second, it can judge the meaning of each finger touch signal, in other words, it can provide users with gesture recognition functions.

The application of the touch screen on the mobile phone can realize the multi-touch function, and the touch screen needs to pass the test before assembly, and the high-current shrapnel microneedle module is a high-performance connection module, which can transmit current, and can carry up to 50A current! The resistance is constant, there is no current attenuation, and the overcurrent ability is strong. With a service life of more than 20w times, it is a long-life and high-performance module, which does not need to be replaced frequently, and can still maintain a consistent level in high-frequency tests, which greatly improves the test efficiency of the touch screen.

As the name suggests, multitouch technology refers to a technology that allows computer users to control a graphical interface with multiple fingers at the same time. Capacitive screen manufacturers are fully touched: 183 of the number, the middle four digits of 2005, followed by 9375. . .

Corresponding to multi-touch technology, of course, is single-touch, single-touch devices have been many years, small size has touch mobile phones, large size is the most common ATM machine and queuing machine in the bank. A multi-touch device consists of a touchable device (e.g., a computer monitor, table, wall) or a touchpad that uses software to identify points that are touching at the same time.

This is different from the common touch displays in the market (e.g., computer touchpads, ATMs in banks), which are only able to recognize single or double points.

Multi-point is to support multiple people to operate together at the same time, my infrared screen has 2 points, 6 points, 10 points.

For example,**,You can use your fingers to pull big and small,Game,You can play with 2 hands,Web pages can also zoom in on a certain area,In general,There are multiple touch points on the screen that can be operated at the same time,The mobile phone will respond。

Multi-touch is relative to the resistive screen, for example, you can use your fingers to pull the big and small, the game, you can play with 2 hands, the web page can also zoom in on a certain area, in general, there are multiple touch points on the screen can be operated at the same time, the mobile phone will have a response to the mobile phone proposed, the general resistive screen mobile phone only supports single touch, and the capacitive screen mobile phone supports 5-point touch or 10-point touch.

The mobile phones of the Symbian system are multi-touch screens, and some Android mobile phones are multi-touch screens, and his best embodiment is that the ** on the mobile phone can be enlarged and reduced by hand, and the touch mode of the mobile phone is realized through thermal induction, which means that if you use an ordinary mobile phone pen, it is impossible to operate the screen of the machine, and you must use the temperature on your fingers. The mobile phone screen that can be operated by ordinary mobile phone pens is a resistive touch screen, and this generation of mobile phone screens has been eliminated with the arrival of iphone4.
