Last year I speculated about Apple adding spatial pen input to #VisionPro. Today they announced it. The API that supports game controllers also supports the Logitech Muse pen (coming later this year). See this developer video of a 3D sculpting app with fine control: https://developer.apple.com/videos/play/wwdc2025/289/ . It has position, buttons, and haptics (Yay!). VisionOS can figure out which hand you are holding it in to help you position toolbars.

@danb the pen support is awesome but leaves me wondering why Apple Pencil Pro is not! You’d think they added all those new motion sensors for more than just rendering shadows on an iPad screen. Maybe software not there yet. Maybe it will need a new pencil hardware. ¯\_(ツ)_/¯
