summary

ForcePinch is a hardware-backed method that maps fingertip pinch force to pointer tracking speed using a pressure-sensor prototype and a per-user cubic-spline mapping. A 20-participant study on 1D slider, 2D tracing, and 3D placement compares ForcePinch to Constant, Go-Go, and PRISM. Results show higher precision but increased time and hand movement; tracking speeds cluster at low and high extremes indicating calibration gaps. Extensions include stroke thickness, bubble-size control, and rhythm-based signatures.
