The touch screen is an absolute coordinate system. To choose which one to point directly, the essential difference between a relative positioning system such as a mouse is the intuitiveness of one position. The characteristic of the absolute coordinate system is that each positioning coordinate has no relationship with the previous positioning coordinate. The touch screen is physically an independent coordinate positioning system, and each touched data is converted to the coordinates on the screen by the calibration data, thus requiring The set of coordinates of the touch screen is stable under the same conditions. If it is unstable, the touch screen cannot guarantee absolute coordinate positioning. The point is not accurate. This is the most fearful problem of the touch screen: drift. In principle, there is a problem that there is no drift in the same touch screen that can be used to touch the same data at the same point. Currently, there is only a capacitive touch screen with drift phenomenon.
Detecting touch and positioning, various touch screen technologies rely on their own sensors to work, and even some touch screens themselves are a set of sensors. The respective positioning principles and the sensors used individually determine the response speed, reliability, stability and longevity of the touch screen.
The same interface between the touch screen interface and the general interface
In addition to the touch screen interface, other user interfaces include web interface, software interface, game interface and mobile phone interface. The touch screen interface has many similarities with them: at the most basic point, they are interactive systems that fall into the category of software design rather than physical design. Secondly, whether it is a touch screen interface or a web interface, they all belong to the graphical user interface design, that is, they all have attributes common to the graphical user interface, such as windows, icons, menus, pointing devices. Only in some special cases, these elements will change accordingly. Again, the touch screen interface and other interface designs are almost identical in terms of both color psychology and graphic design.
Finally, the design concept of the touch screen interface and other interfaces is the same, that is, "people-oriented", so that users can see at a glance after the first contact with this interface, you can easily use it without much training, so that the user is the first time Get a happy feeling when you operate.
The difference between the touch screen interface and the general interface
In addition to the touch screen interface, other user interfaces include web interface, software interface, game interface and mobile interface. The web interface and mobile phone interface can be said to be two typical representatives. To describe the differences between the touch screen interface and other user interfaces, compare them to two typical interface representations and then draw conclusions.
