A system includes: a substrate; a first electrode proximal a center on the substrate; and a second electrode interposed between the first electrode and an edge on the substrate. The system also includes a first coupling region: arranged on a first planar region of the baseplate; offset from the first electrode by a first height; and coupling to the first electrode to yield a first electrical value at the first electrode responsive to application of a force magnitude proximal the center. The system further includes a second coupling region: arranged on a second planar region, offset above the first planar region, of the baseplate; offset from the second electrode by a second height, less than the first nominal gap height; and coupling to the second electrode to yield a second electrical value, approximating the first electrical value, at the second electrode responsive to application of the force magnitude.

System for detecting and characterizing touch inputs at a human-computer interface

A touch assembly includes: an outer tip; an inner tip; a circuit board; a vibration sensor; and a spring element. The outer tip includes a distal end defining an outer contact surface. The inner tip: is arranged concentrically within the outer tip; extends from the distal end of the outer tip; and defines an inner contact surface. The circuit board is arranged over a proximal end of the outer tip. The spring element: is interposed between the circuit board and the inner tip; couples the inner tip to a reference potential; and is configured to, during a haptic feedback cycle at a touch sensor in response to application of the inner tip toward the touch sensor, yield to locate the inner contact surface coplanar with the outer contact surface. The vibration sensor is arranged on the circuit board and configured to output vibration signals during the haptic feedback cycle.
