Organizing the screen into multiple layouts
One very common, but very poor, design decision in HMI development is to group multiple different screen responsibilities or way too much information on a single screen. There are many reasons why this is bad. Some reasons are as follows:
- Screen disorganization
- Cluttered appearance
- Poor usability
- Overloading the operator with irrelevant information
These are just a few reasons why screen organization is very important. However, one of the most important is overloading the operator with information. Generally, you only want to display the information that is relevant to the operator. If you include too much information, the operator can easily become confused or they can tune the information out and, ultimately, ignore important developments. One common way to combat this is to split an HMI application into multiple different screens.
Generally, screen organization can be determined with the one-sentence rule...
