What is an Activity Indicator?

An Activity Indicator is a visual element, often represented as a spinner or pulse, that signifies to users that ongoing processing is taking place. It serves to inform users that the system is actively working on a task, thereby managing their expectations regarding response times.

When to use Activity Indicator?

You should use an Activity Indicator when a process requires a noticeable amount of time to complete, such as loading data, submitting forms, or performing background tasks. It enhances user experience by providing feedback that the system is engaged and the user should wait.

When not to use Activity Indicator?

Avoid using an Activity Indicator for very quick operations that complete in less than a second, as it can be unnecessary and may confuse users. Additionally, if the operation is instantaneous or if feedback can be provided through other means (like a confirmation message), an Activity Indicator may not be required.

What is the anatomy of an Activity Indicator?

The anatomy of an Activity Indicator typically includes a rotating spinner or pulsing dot, which visually conveys activity. It may also include textual information or context, such as "Loading..." to clarify what the system is processing. The design should be simple and unobtrusive, ensuring it does not distract from the overall user interface.
