Nowadays, whether it is work or entertainment, many small partners are inseparable from the touch screen. Indeed, with less cumbersome mouse and keyboard, your fingers are more flexible and convenient. But have you ever wondered why most computers today do not add touchscreens? To say that it is the cost problem, the low-end computers do not use touch screens. Nowadays, high-end computers often do not support touchscreens.
In fact, it is mainly because the touch screen on the computer is really useless. For example, using a desktop computer, the large screen at 20 inches can touch not only fingers but also entire arms through finger touching operation. Thinking is tiring. And such a large screen, dense fingerprint cleaning up is also very troublesome!
In fact, although finger touch looks simple, the accuracy and efficiency of input are not as good as traditional keyboard and mouse. If there is a need for drawing, a high resolution digital board can clearly draw more fine lines than fingers. For notebook computers, which are much lighter than desktop devices, which can meet the needs of mobile devices, touch-screen not only has the above problems, but also causes the problem of over coincidence with the use of tablet computers, and reduces product sales.
Take Microsoft as an example. Once on Windows 8, Microsoft made a trial of compatible touch / key mouse, and removed the start menu. Then, this nondescript product received a lot of bad reviews. The Apple Corp's approach is to integrate Mac OS and iOS, until the mobile phone and computer share a slightly different iOS interface, so Apple's Mac series is equipped with touchpad.
We have to say that the integration of systems and devices between mobile phones and computers is a major trend. At the present level of technology, we still have a long way to go.
