An electronic device includes an enclosure and a keyboard positioned within the enclosure. The keyboard includes a substrate and a key mechanism. The key mechanism includes a keycap support mechanism, a keycap supported by the keycap support mechanism and movable relative to the substrate, a ferromagnetic component attached to the keycap support mechanism, and a selectively magnetizable magnet. The selectively magnetizable magnet system may include a magnetizable material and a coil configured to selectively magnetize and demagnetize the magnetizable material. The key mechanism may include a collapsible dome biasing the keycap toward the extended position.

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.

Supplementing the movement stroke of a trackpad with a haptic response is one way to restore some or all of a reduced trackpad feel and overall performance caused by a reduction in the movement stroke. However, incorporating haptic responses in a clickable trackpad may interfere with accurate force measurement using physical movement of the trackpad as a proxy. The following describes haptic trackpads with anisotropic compliant spacers. The disclosed haptic trackpads permit selective haptic responses to a user, while also permitting accurate force measurement using displacement of a sensing surface caused by the user's finger(s) as a proxy.

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.

A keyboard device is disclosed. The keyboard device includes a base, a key top, a film actuator, a position sensor, and a controller. The key top is movably arranged on the upper surface side of the base. Disposed between the base and the key top, the film actuator bends according to an applied voltage. Also disposed between the base and the key top, the position sensor detects a position of the key top. The controller applies a voltage to the film actuator in order to generate a repulsive force corresponding to the position of the key top detected by the position sensor.

A processor may identify that a user is interacting with a device, where the interacting is identified from the user touching the device. The processor may receive tactile data associated with the user from one or more tactile sensors. The processor may extract, utilizing an AI model, one or more features of the tactile data. The processor may classify, utilizing the AI model, the tactile data as having a tactile data characteristic. The processor may output the classification to an interaction management module.

A haptic peripheral includes a housing and a haptically-enhanced user input element. The haptically-enhanced user input element is configured to receive an input from a user, and includes a mechanical key having a keycap with a user contact surface configured to contact the user and a smart material actuator integrated onto the user contact surface of the keycap. The smart material actuator is configured to receive a control signal from a processor and is configured to deform at least a portion of the user contact surface relative to the keycap of the mechanical key in response to the control signal from the processor to thereby provide a haptic effect to a user of the haptic peripheral. The haptic peripheral may also include a braking actuator coupled to the mechanical key to hold the mechanical key in a depressed position to indicate an inactive status to a user. In addition, the haptic peripheral and the haptically-enhanced user input element may be modular.

A haptic feedback planar touch control used to provide input to a computer. A touch input device includes a planar touch notice that inputs a position signal to a processor of the computer based on a location of user contact on the touch surface. The computer can position a cursor in a displayed graphic environment based at least in part on the position signal, or perform a different function. At least one actuator is also coupled to the touch input device and outputs a force to provide a haptic sensation to the user contacting the touch surface. The touch input device can be a touchpad separate from the computer's display screen, or can be a touch screen. Output haptic sensations on the touch input device can include pulses vibrations, and spatial textures. The touch input device can include multiple different regions to control different computer functions.
