This looks at how much mental effort someone can handle at once when interacting with a system. It explains that people have a limited capacity for processing information, so if too much is presented at the same time, it can become overwhelming and lead to mistakes.

This is especially relevant in physical activities where users are already focusing on movement and coordination. If instructions or feedback are too complex or distracting, it can take attention away from the task itself. Keeping information simple, clear, and well-timed is important to avoid overload and help users stay focused.
