Hardware Architecture
The Interface Pen relies on a custom IF-X1 Motion Coprocessor embedded directly above the nib assembly. This IC handles raw signal processing locally, removing the calculation burden from the host device.
By computing pressure curves and tilt matrices on the pen itself, we transmit a pre-calculated vector package over Bluetooth 5.2 Low Energy, saving approximately 4.2ms of host-side processing time compared to passive styluses.
