Vibration is used as a haptic feedback mechanism for a range of commercial applications. A study of non-contact vibration measurements using laser Doppler vibrometry for haptics is presented for a range of devices and applications. Example measurements presented include: direct measurements on piezo haptic transducers to resolve displacement profiles, response of a mobile phone driven by a linear resonant actuator, scanning vibrometer measurements of a human hand showing the propagation of vibration as 3D deflection shape, wave propagation measurements on touch screens, push response measurements of tactile metal domes and keyboards, and novel use for air-coupled, ultrasonic haptic devices (“ultra haptics”).
