Nowscreen touch technology has spread throughout every corner of life, it is in the rapid development and progress stage. At the very beginning, single-touch can only recognize a single finger touch. The appearance of smart phones and smart tablets marks the emergence of multi-touch technology. Now ten-touch has become the selling point of new products. Screen touch technology has become very hot in just a few years. What's the difference between single-touch and multi-touch? Is the more touch points the better?
1、Single-touch technology
As the name suggests, single-touch technology means there is a single touch point, that is, only one finger’s click, movement and touch can be recognized at one time. The appearance of the single-touch screen has made a qualitative leap in the human-computer interaction mode, which can no longer be limited to physical buttons, only one screen can solve all operations. For example, every day we operate on the automatic checkout device at the nearby supermarket, the ATM machine at the bank, or the check-in terminal at the airport, all of which can be operated by a single touch screen. In the past, we can only operate through the mechanical buttons around the screen, the single-touch screen has realized the transformation of human-computer interaction which allow us to eliminate the traditional mechanical buttons. Such a human-computer interaction screen brings us two major benefits:
1) the device design space is optimized, we no longer need to consider the location of physical buttons, it is especially conducive to small devices.
2) because buttons can be bound to any application in the operating system, the device can use an infinite number of virtual buttons.
The advantage of single-touch is that one finger touch input prevents the wrong operation behavior of accidental touch. So it is more suitable for equipment that requires strict operation, such as ATM machines, digital cameras, multi-function machines in hospitals and other equipment.
2, multi-touch technology
What does multi-touch technology mean? Literally, touch different points of the screen at the same time to achieve simultaneous operation of different touch parts. Professional definition can be called multi-touch, multi-point sensing, multi-sensing, The human-computer interaction can be realized under the simultaneous operation of multiple touch points. Highly free operation, users can freely release their hands, so that multi-touch technology is more affirmed by people. The emergence of multi-touch technology has opened a new door for us, humanized free operation brings us a better usage experience.
Multi-touch technology is used in every aspect of our lives. For example, try to enlarge a picture on the screen with two fingers, does the picture enlarge at one time? The same operation, which can be applied while the camera is shooting, allows two fingers to slide to zoom and zoom in on distant objects. For example, when playing a game on a mobile phone or tablet device, you need to walk while attacking the enemy, and these actions must be done at the same time, and multi-touch can achieve this operation. With a tablet drawing app, for example, the harder you press your finger, the larger the finger contact area, and the thicker the lines will be. There are many application scenarios of multi-touch technology, such as magnification with two fingers, rotation magnification with three fingers and so on.
3, ten point touch technology
Today's multi-touch control technology can support at most ten-point touch, in a nutshell, it supports ten fingers to touch and control the screen at the same time. Smartphones generally support 2-5 touch points. The mobile phone will not apply the ten-point touch technology, because there is no practical application requirements. The more points of multi-touch, the more mobile phone graphics card memory, will lead to mobile phone jammed. Generally speaking, ten-point touch technology will be applied in the drawing machine, or tablet-type drawing computer and other painting fields, when drawing, you need to constantly switch the Angle, zoom in and out, ten-point touch control will be more flexible. Or a large gaming tablet, which requires 10-point touch when playing games with complex manipulation.
In summary, is the more touch points on the screen the better? Do you have the answer in mind? In fact, in different application scenarios, we will choose different quantity of touch points. Single-touch and multi-touch play their own role in their respective fields. Multi-touch technology is certainly more advanced, but single-touch technology has its own market. Perhaps the touch control technology in the future will support more touch points, and support multiple people to play games, draw, manipulate, etc., on the same screen at the same time, without affecting each other. We believe that with the continuous development of touch control technology, this scene will eventually come true. Let's look forward to it!
