The subject matter of this specification describes a method that includes determining when to send a user selection of a first key on a keyboard to an operating system, where the operating system supports shortcut key combinations. The device identifies the user selection of the first key, as input for an application. The device determines that the first key is part of a shortcut key combination. The processing device determines whether a cursor is visible in a user interface provided by the application. Upon determining that the cursor is visible in the user interface, the device waits for another user selection of one or more remaining keys of the shortcut key combinations before sending the first key to the operating system. Upon determining that the cursor is not visible in the user interface, the device sends the first key to the operating system without waiting for another user selection.

A method of making an actuator switch is disclosed. One method including: receiving a threshold amount of pressure on a top surface of a flexible film; in response to receiving the threshold amount of pressure, contacting a first electrode with a second electrode; in response to receiving the threshold amount of pressure, generating i) a first capacitive connection between a row electrode and the second electrode and ii) a second capacitive connection between a column electrode and the second electrode; in response to the first electrode contacting the second electrode, generating, by a piezoelectric actuator, haptic feedback; and in response to the generating the first capacitive connection and the second capacitive connection, providing an input detection signal.

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 sensing system for a keyboard. Each key sensor comprises passive and active resonant circuits. The passive resonant circuit has a resonant frequency and the active resonant circuit excites the passive resonant circuit at the resonant frequency. A sensor driver drives the active resonant circuit with an RF drive signal, a multiplexing system multiplexes the drive signal such that simultaneously driven key sensors are separated by at least (k−1) keys, and a detector detects a level of RF signal from a driven key sensor for sensing a position and/or velocity of a key.

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.
