Could you build this?
No Accessing undocumented Apple Silicon hardware accelerometers via IOKit HID at 1,000Hz and matching microsecond typing force requires reverse-engineering private macOS hardware interfaces.
What it would actually take: The app requires low-level Swift or Objective-C/C++ interacting with private macOS IOKit frameworks and Mach kernel primitives to poll the undocumented Sensor Processing Unit (SPU) HID streams without root privileges. It must handle high-frequency sensor signal processing to extract impact velocity vectors and synchronize them with low-latency CoreAudio buffers within single-digit milliseconds. This necessitates specialized reverse engineering of proprietary Apple hardware and real-time audio systems engineering.
