What s the difference between a single touch and a multi touch?

Multi-touch technology, which allows users to input at the same time in multiple locations on the screen, is a completely different way of human-computer interaction compared to the traditional mouse and keyboard input method. The most prominent feature of this technology is that multiple users can interact with the machine at the same time, each user can operate the screen with multiple fingers, and more importantly, the system can also recognize the gesture of the fingers.

For example, you can zoom in and out of an image with two fingers, move objects with one finger, and create a pinching effect.

Most of the multi-point touch screens are capacitive screens, and the response is also more sensitive than the resistive screen, and it is also good for games that support multi-point, which will be relatively expensive.

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.
