Report: Next Apple Watch to trade physical buttons for touch-sensitive ones
Fast Company reports that a source with knowledge of Apple's plans says that the next Watch will feature the same button configuration as the current model, but the new buttons will be based on haptic feedback, which means they will vibrate at the user's touch.
As with all things it uses, Apple has its own name for this technology – Taptic Engine. While the digital crown will still physically rotate to navigate through content, but the button press will be simulated by the so-called Taptic Engine.
The report also mentions that Apple might add these solid-state controls in the next Watch that's supposed to be unveiled this fall, but if not, they will surely be included in the 2019 model.
