Cognitive load theory states that the working memory can only hold a few pieces of information at a time.
Good car designers know that the vehicle’s interface should take up as little working memory as possible in order to help drivers focus on the road. If a driver becomes distracted by confusing controls, the results could be fatal.
The importance of cognitive load as a design consideration is easy to grasp in the context of driving. It’s a fast-paced environment where accidents can be sudden and graphic.
What most designers overlook is the fact that cognitive load factors into nearly everything we make at some level or another. When we hear a ping from our phone, sit on an uncomfortable chair, or find ourselves obsessively checking the news, the weight of our cognitive load increases.
Of course, cognitive load in these situations won’t cause immediate harm, but the cumulative cost is significant regardless. Being distracted all day, every day degrades our quality of life, and it steals our focus from the activities and relationships that matter.
Our working memory is our life. Be mindful of how much of it your design choices might demand.
