Is the perceived present 100 milliseconds long, or is it closer to 3 seconds? Why does it feel simultaneous when we touch our nose and our feet at the same time, even though the nerve signals travel different distances? Is the "now" we hear and see equally long? This project is dedicated to these and other questions related to time perception and the experience of the present moment. The focus of the reduced design and its graphics is on effectively conveying the book's content. Through practical examples, including some supported by "Augmented Reality", it becomes an interactive journey. What started with the question, "How long is the now?" ends with many answers about how much information we can actually perceive in individual moments. These findings, drawn from psychology and neuroscience, can also be practically applied to design or confirm several well-known design principles. Red Dot Design Award winner 2020.
