Understanding Softness and Perception

The video explores the sensation of softness, focusing on both material properties and psychological factors. It discusses how fabrics like cashmere feel soft due to their smoothness and compressibility, and how our brain perceives softness through tactile information. Studies show that softness perception is influenced by how pressure is distributed on our fingers. The video also promotes Skillshare, highlighting a course on photographing coffee swirls.
