In some examples, techniques are provided for quick haptic feedback, without the use of a controller, which is local to individual, non-actuating keys, such as keys of a thin keyboard or keypad. The haptic feedback may be in the form of a simulated key-click feedback for an individual key that is pressed by a user such that the finger used to press the key feels the tactile sensation. The haptic feedback mimics the tactile sensation of a mechanical key (e.g., buckling spring, pop-dome key switch) to give a user the perception that they have actuated a mechanically movable key.

A control panel for a vehicle. The control panel includes a decorative layer and a control assembly. The decorative layer has a visible face and a rear face opposite to the visible face. The control assembly has a front face and a rear face opposite to the front face. The front face of the control assembly faces the rear face of the decorative layer. The control assembly is fixed to the decorative layer and includes a support film, a pressure sensor and a light-emitting diode. The pressure sensor and the light-emitting diode are printed on the support film.

A multi-modal sensing transducer may include a force concentrator having an external sensing surface. The multi-modal sensing transducer may also include at least one electrode coupled to the force concentrator. Further, the multi-modal sensing transducer may include at least one force sensitive element disposed adjacent to the at least one electrode. Moreover, the multi-modal sensing transducer may include at least one air gap disposed between the at least one electrode and the at least one force sensitive element.
