Each load takes up a different amount of mental resources Visual loads (looking a screen) takes more than Motor (pressing a button) Cognitive loads (remembering a date) takes more than visual (looking at a person) The order of Loads using the most resources Cognitive Visual Motor

Minimize Motor Switching

Don't allow people to switch back and forth between motor loads Using a mouse only  -> Using a Keyboard to navigate Motor Switching can cause people to lose focus or become frustrated For accessiblity design, minimizing motor switching can be useful to those using accessible devices

Sometime You May Increase Loads
