Cognitive Overload

A state in which the amount of information or the complexity of a task exceeds a person's processing capacity, leading to reduced performance, comprehension, or decision-making ability. In accessibility contexts, blind users of visual assistance technologies may experience cognitive overload when processing assessment descriptors alongside the original VAT task, managing obfuscation controls during dynamic video calls, or interpreting multiple sources of information (verbal descriptions, haptic cues, audio tones) simultaneously.
