When creating or choosing an icon, the clarity of an icon is important. If you can't think of
a suitable symbol within 5 seconds, it is unlikely that an icon will be able to
can convey the meaning clearly at all.
So they should be used in a meaningful way. Unclear icons are not helpful and get
in a user interface.

Clarity is therefore one of the most important features of an icon. Used correctly, it is a
great way to convey content in a simple and purposeful way.
The KISS principle can be applied to elements on the user interface as well as to
icons. The principle says, keep the symbols as simple as possible and
schematic to focus on the basic features.

But how do I choose the right icon?

• Clarity & Recognizability: The meaning of the icon must be clear.
  Standard icons like the magnifying glass or an envelope should not deviate from the learned
  deviate.

• Simplicity: An icon serves the purpose of simplification and makes the application
  more user-friendly. Therefore, an icon should not be overloaded and freed from unnecessary
  ballast.

• Aesthetics: The visual attraction supports the user experience.

• Size & Scalability: Icons are easy to click or touch. The icon
  should therefore remain easily recognizable even at different sizes.

Established icons

When choosing the right icon, however, the wheel should not be reinvented. The
understanding of users is based on experience. Symbols such as house, magnifying glass, mail, etc. are
established icons, which are also used internationally and recognized by the user.

Discrepancy

Icons that are contradictory to each other frustrate, confuse and have a negative effect on the on the user experience. Icons with similar meanings should be avoided and clearly defined.

Support

The use of symbol and text supports clarity and ensures that misinterpretation, and thus misinterpretation, and thus frustration, is minimized.

Consistency

Intuitive design goes hand in hand with consistent design. When similar elements have a

Icon sets should form a visual unit, i.e. stylistically come from the same pen. The
Use of a color scheme, as well as consistent style attributes (sizes, stroke width,
rounded/cornered, etc.) lead to a homogeneous image.
