Eleven years ago, Apple introduced 3D Touch as a tactile revolution. It promised shortcuts and previews by pressing the screen with varying intensity. However, the technology disappeared from later iPhones, replaced by more common touch gestures. What happened to that promise of differential interaction? We analyze its brief reign and its silent death.
The technical complexity behind a pressure sensor 🔧
3D Touch integrated a layer of capacitive sensors beneath the panel, capable of measuring micro deformations of the glass. This matrix detected four levels of pressure, translating them into actions like Peek and Pop. However, the hardware added thickness and cost. Apple sacrificed functionality in favor of thinner screens and larger batteries, leaving developers with an orphaned API that few truly exploited.
The phantom button no one missed 👻
Apple sold us a digital sixth sense: pressing the screen like it was an NES controller. But the public, confused, preferred to hold their finger still or swipe it. In the end, the company simplified everything with a long press. In other words, we went back to basics. 3D Touch died like that friend who insists on telling jokes no one understands: with dignity, but in solitude.
