Our Presentations at a Glance

Piezo components for targeted haptic feedback

With some control panels, it makes sense to acknowledge entries via selective haptic feedback without causing the entire control surface to vibrate. Piezo components are perfect for this because they ensure targeted, selective lifting movement of the user interface (local feedback). This short vertical movement…

Exciter and Voice-Coil actuators for general haptic feedback

Touch panels and other smooth user interfaces are easier to use if they acknowledge inputs with a signal. Our exciters and voice coil actuators are haptic components that are attached below the user interface and cause the entire surface to vibrate briefly when touched (global…
