A device including a piezoelectric actuator that can detect the actuation force and provide haptic feedback. The longitudinal extension of the actuator, generated for this purpose, can be reinforced in the desired direction by a deformable metal sheet. The deformable metal sheet is adhered on and has a borehole for pressure equalization.

According to various embodiments of the disclosure, an electronic device may include a housing including a first plate facing in a first direction and a second plate facing in a second direction opposite to the first direction, and a key assembly disposed on at least part of the first plate and including a plurality of keys for inputting data by a pressing operation, wherein the key assembly includes a keycap, a printed circuit board, a support structure disposed on the printed circuit board to support the keycap and supporting a pressing operation of the keycap, a contact point portion disposed between the support structure and the printed circuit board, a movable portion coupled to the support structure in the second direction, and an actuator coupled to the movable portion and providing a force for moving the keycap in the first direction or the second direction depending on whether the actuator is activated.

A haptic keyboard typing profile personalization system of an information handling system comprising a processor to receive a plurality of haptic hardware typing behavior parameter values for a user via a piezo haptic keyboard controller and input the plurality of haptic hardware typing behavior parameter values into a personal typing profile comprising weight matrices of a machine learning neural network correlating the input with one or more haptic setting values defining haptic feedback movement one of a plurality of piezo electric elements of a haptic keyboard to identify an output describing the personal typing profile with learned, custom haptic setting values optimized for the user, and the piezo haptic keyboard controller applying a voltage of specific magnitude, polarity, or duration to the haptic keyboard to cause a piezo electric element to operate according to the personally typing profile learned, custom haptic setting values.

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 portable computer includes a display portion comprising a display and a base portion pivotally coupled to the display portion. The base portion may include a bottom case and a top case, formed from a dielectric material, coupled to the bottom case. The top case may include a top member defining a top surface of the base portion and a sidewall integrally formed with the top member and defining a side surface of the base portion. The portable computer may also include a sensing system including a first sensing system configured to determine a location of a touch input applied to the top surface of the base portion and a second sensing system configured to determine a force of the touch input.

An electronic device has a keyboard with an internal membrane. The membrane has a set of strain gauges configured to respond to a key press, such as when a collapsible dome collapses into contact with the membrane. The strain gauges are connected in a half Wheatstone bridge configuration and are positioned on the membrane in order to limit effects of temperature and subtle flexure of the membrane. The strain gauges are also configured to magnify detection of a resistance differential when a keycap is pressed with sufficient force.

A keyboard, touchpad, and palm rest haptic response system may comprise a coversheet to identify a keyboard, a touchpad, and a palm rest on a C-cover for an information handling system, a haptic palm rest and touchpad feedback assembly disposed beneath the haptic palm rest area including haptic touchpad, and a haptic keyboard feedback assembly disposed beneath the keyboard. Keyboard controller and palm rest and touchpad controller may receive piezo actuation signals from keyboard piezoelectric elements and touchpad and palm rest piezoelectric elements, respectively, and send a haptic feedback control signals to the respective keyboard piezoelectric elements or palm rest and touchpad piezoelectric elements to cause keyboard haptic feedback or palmrest or touchpad haptic feedback at an actuation location.
