Microinteraction

A brief, high-frequency interaction with a device that typically takes a sighted user less than four seconds to complete, such as checking the time, glancing at a notification, or adjusting the volume. Microinteractions are significant for accessibility because they expose efficiency gaps between sighted and visually impaired users — tasks that take seconds with visual feedback can take considerably longer when mediated through a screen reader. Supporting efficient microinteractions is a key challenge in mobile and wearable accessibility design.
