What does resolution refer to in relation to control sites?

Resolution in relation to control sites specifically refers to the degree of fine control required for an activity. This concept is critical when evaluating assistive technologies, especially those designed to aid individuals with disabilities in performing tasks using various input methods, such as touch screens or switches.

Fine control is essential in many applications, as it dictates how precisely a user can interact with the technology. Higher resolution means that the user can make more precise movements, resulting in better accuracy when selecting options or controlling devices. For example, in assistive communication devices, the ability to select letters or icons with fine control can significantly improve the user's ability to convey messages effectively.

Understanding resolution helps in choosing appropriate assistive devices, ensuring they are well-suited to the user's specific needs and capabilities. When assessing control sites, recognizing the importance of fine control allows practitioners to tailor interventions that enhance user experience and functional independence.
