Turbulent Touch: Touchscreen Input for Cockpit Flight Displays
summary
Comparative study uses a Microrola motion platform with ISO 2631 low/ high profiles, 18 non‑pilot participants, and three input methods: touchscreen, trackball, and a transparent stencil overlay with cutouts. Tasks include 5 real cockpit actions (tiny 8/16 mm taps, 26 mm keypad, sliders, dials, pan/zoom). Main findings: touch is faster for coarse targets even in heavy turbulence, trackball is superior for precise pointing at high vibration, and the stencil reduces small‑target errors but causes lift‑off bounces unless a 200 ms timeout is applied; wrong‑target errors reach ~12% at high vibration.
