These consistencies and standards between digital products, we prevent users from having to relearn what functions are like. For example, check-in counters in hotels are usually located at the front desk. This consistency meets the expectations of customers, who always expect to find check-in at receptions. This is maintained as a consistency and standard between physical places and we must also apply it to digital products. Error prevention good error messages are important, but the best designs carefully prevent problems from occurring.
We must eliminate error-prone conditions. We can say that there are two types of errors: slips and mistakes. Slips are unconscious E-commerce Photo Editing mistakes caused by inattention. Errors are conscious based on a mismatch between the user's mental model and the design. Recognition instead of remembering minimize user memory load by making items, actions, and options visible. The user should not have to remember interface information. Information needed to use the layout (for example, field labels or menu items) should be visible or easily retrieved when needed, without you having to remember where to go. Humans have limited short-term memories. Interfaces that promote recognition reduce the amount of cognitive effort required from users.
For example: it is easier for most people to recognize the capitals of countries, instead of having to remember them. People are more likely to answer correctly the question is lisbon the capital of portugal? Instead of what is the capital of portugal? This must be paramount when applying usability heuristics. Flexibility and efficiency of use we must allow users to customize frequent actions for them. Shortcuts, hidden from novice users, can speed up interaction for the expert user, so that the design can satisfy both inexperienced and experienced users. Flexible processes can be carried out in different ways, so that people can choose the method that works best for them.
