The concept of “empty space”, also known as whitespace, is familiar to visual designers. It refers to intentionally leaving empty space around and between different design elements. It can be very noticeable (macro) or very subtle (micro). Its goal is to help the users to navigate their way through the design outputs. This reduces the users’ cognitive load. Cognitive load refers to the limited capacity of our working memory to process information at any given time. In service design, empty space is yet an undiscovered, but potentially very powerful, tool.
