O’zaro ta’sirli interfeysni loyihalashda hisobga olinishi kerak bo‘lgan operatorning asosiy xususiyatlari

6. Multilanguage considerations
Today’s diverse working environment requires the use of multi-language support in operator interface products. If there’s a chance your application will require translation, keep in mind that some languages might often take up a larger text area than the English equivalent. You should, therefore, make text areas large enough to accommodate various languages.
7. Watch your MLAs
Multi-letter acronyms and other abbreviations only work when all users understand their meaning, so spell out acronyms whenever possible. If you don’t have enough room to place the actual phrase that would make sense, note that your screen might be too crowded or too small.
8. Use images
Most people use their vision more than any other sense, making pictures and illustrations a great way to quickly draw a user’s attention. In a pump application, for example, you can use an illustration of the pump itself and highlight specific areas that need maintenance or adjustment.
9. Group data together
Just like placing a pump image on the screen to draw attention, you should place any elements associated with the pump close to the image. This could include the start and stop buttons and readouts for current, temperature, volts, hours run, etc. Placing this information elsewhere on the screen can lead to confusion and limit operator productivity.
10. Plan for change
Dare to assume that the application will eventually be used on a different size display. For whatever the reason—customer request, panel got smaller, panel got bigger, need color, don’t want color, etc.—sometime there may be a need to use a different display. Prepare by keeping elements on the screen at a high contrast to the background. For example, use a black background and light-colored elements (like light gray) in your base design. This will be very visible on both color and gray-scale displays.

Plan for portability. Assume an HMI application will one day run on another interface and design it to move. Using panels within the same family, such as the new HM i family from Eaton, makes your application as scalable as your hardware, because a click of a button resizes your screen.
