What does 'resolution' refer to in the context of control?

In the context of control, 'resolution' specifically refers to the smallest separation that can be distinguished between two objects or the smallest change that can be detected by a control system. This concept is crucial because it dictates how finely a system can differentiate between different states or positions.

For instance, in assistive technology or digital input devices, a higher resolution would allow for more precise control and input, enabling users to perform tasks with greater accuracy. This is particularly important for individuals who may rely on assistive devices that require precise movements, as a higher resolution can lead to better performance and ease of use in everyday tasks.

Understanding resolution helps in evaluating the effectiveness and suitability of control mechanisms in various applications, ensuring that they meet the specific needs of users, especially in fields like rehabilitation engineering and assistive technology.
