Cognitive load, in the context of augmented reality, refers to the mental effort and processing capacity required by users to comprehend and interact with AR content. AR applications should strive to minimise cognitive load to ensure that users can engage with the experience efficiently and effectively. High cognitive load, often caused by complex interfaces, information overload, or difficult interactions, can lead to user frustration and reduced usability. Designing AR experiences with lower cognitive load involves simplifying interfaces, providing clear instructions, reducing extraneous information, and optimising the flow of information. By minimising cognitive load, AR developers can enhance the user's ability to focus on the content and achieve a more enjoyable and user-friendly AR experience.
