Pace Layers help us understand how different parts of a system change at different speeds, and this idea is super useful in interaction design. For example, the core technology layer—like hardware or network infrastructure—evolves slowly, while the user interface or trends in app design can change rapidly. This means interaction designers need to create experiences that feel fresh and relevant now but also stay adaptable as trends shift. It’s a balancing act: designing for fast-moving layers like aesthetics while keeping an eye on slower layers, like the foundational tech, to ensure the work remains functional and scalable over time. Understanding these layers helps designers future-proof their work while staying flexible for the next big change.
