We all want our projects to be fast. We agonize over JavaScript bundle sizing, our chosen CSS preprocessor’s impact on stylesheet bloat, caching schemes, and more as we head down the performance rabbit hole. But here’s the rub: doggedly chasing kilobytes isn’t an efficient way to improve your project’s performance if users aren’t be able tell the difference. At the end of the day, perceived performance—what users feel and experience while using your app—is what truly matters.
This isn’t easy. Humans are imprecise beings, and how we perceive the world around us is fraught with fascinating quirks. Improving perceived performance is likewise an incredibly challenging prospect. If people don’t perceive time accurately, how can you possibly hope to build to meet this nebulous standard?
In order to make experiences that feel satisfying, you need to understand the basic psychology behind how humans perceive time in the world around them. This opens the door to a universe of possibilities and a deeper connection with the users we all serve.
Eli Fitch discusses the psychological basics of how people sense time and explains how to use this understanding to create experiences that feel fast, tactile, and satisfying.
Topics include:
Eli Fitch is a frontend developer with a passion for web performance, animation, and all things 3D. He leads a team of amazing engineers making a WebGL event diagramming app at Social Tables, a startup in his hometown of Washington, DC. He also organizes the DC CodePen meetup and dabbles in design, 3D art, and game development. When not in front of a computer, he restores his perpetually broken stable of 1970s motorcycles and attempts to keep his historic row house from collapsing in on itself like a dying star.
