What are examples of physical constraints used in the design process to suggest actions?

Physical constraints in the design process are often due to the characteristics and limits of the physical world. They can serve to suggest or limit certain actions. Some examples of physical constraints are:

- Shape and size: An object can be designed in such a way that it can only be held or operated in a certain way. For example, a door handle can be designed so that it can only be turned and not pushed.

- Placement and arrangement: The arrangement of elements can influence the way they are used. For example, keys on a keyboard can be arranged in such a way as to facilitate typing.

- Material and texture: The choice of material and texture can influence the handling of an object. For example, a non-slip grip on a tool suggests that it should be held firmly.

- Color and contrast: Colors and contrasts can serve to highlight certain elements and draw attention to them. They can also serve to suggest certain actions, such as pressing a highlighted button on a remote control.

Question was asked on:

Es gibt vier Arten von Einschränkungen.Physisch, die Eigenschaften der physischen Welt nutzen, um Handlungen zu suggerieren; kulturell, die auf kulturellen Normen basieren, weil "jede Kultur einen Satz von zulässigen Handlungen für soziale Situationen hat"; semantisch, die sich auf die Bedeutung einer gegebenen Situation verlassen, um die Menge der möglichen Handlungen zu steuern; und logisch, die gute alte Logik nutzen, um die logischen Beziehungen zwischen "der räumlichen oder funktionalen Anordnung von Komponenten und den Dingen, die sie beeinflussen oder von denen sie beeinflusst werden" zu nutzen.
