USB HID
A device protocol class defined in the USB specification, covering human interface devices such as keyboards, mice, and touchscreens. Operating systems include built-in generic HID drivers, allowing devices that conform to HID descriptor specifications to be recognized without additional drivers, and enabling simulation of touch and keyboard input for phone control.

The ESP32-S3 exposes two HID interfaces via the TinyUSB software stack (a relative mouse and an ASCII keyboard), and the host can send commands such as move, click, and type to it over Wi-Fi or BLE.
The USB HID protocol itself contains no device identity authentication mechanism, so any microcontroller that can enumerate as HID can inject input events into the host; this is a physical-layer breakthrough for bypassing Apple's app signing system.
Because the mouse emulated by the ESP32-S3 uses relative coordinates, each movement accumulates error, so calibration is needed through periodic homing and jiggling the pointer before clicking to avoid click offset.
