Abstract: Innovative techniques to design and generate haptics waveforms are proposed. The proposed techniques enable consistent haptics user-experience to be enable despite variations among different haptic actuators. Arbitrary waveforms may be generated without selecting from a list of pre-determined waveforms.

Abstract: In some aspects, an electronic device may receive a plurality of haptic signals associated with a plurality of haptic events, wherein the plurality of haptic events overlap in a time domain. The electronic device may generate a mixed haptics signal that combines the plurality of haptic signals in a mechanical acceleration domain, wherein the mixed haptics signal preserves timing or synchronization information associated with the plurality of haptic signals. The electronic device may generate an output stream to be provided to a haptic actuator, wherein the output stream includes a pulse code modulation (PCM) voltage signal based on the mixed haptics signal that combines the plurality of haptic signals. Numerous other aspects are described.

Abstract: In some aspects, an electronic device may display a keyboard user interface on a touchscreen display panel. The electronic device may detect a key press interaction with the keyboard user interface. The electronic device may trigger one or more haptic actuators to generate a vibration waveform associated with a haptic pattern that is based at least in part on a context associated with the key press interaction. Numerous other aspects are described.

Abstract: An apparatus (101) includes a fingerprint sensor (102) including a wakeup sensor portion (202) and a transmitter portion (207). The wakeup sensor portion (202) may be configured to send an activation signal (204) to the transmitter portion (207) due to a contact indication, corresponding to contact with an outer surface of the apparatus (101) in the fingerprint sensor area that equals or exceeds a contact indication threshold. A control system (106) of the apparatus (101) may include: a fingerprint sensor control system portion (206a) configured for controlling the transmitter portion (207) and for determining, based at least in part on fingerprint sensor data obtained from an object in contact with the outer surface of the apparatus (101) in the fingerprint sensor area, whether the object is a finger: a fingerprint image data processing control system portion (206b); and a wakeup reduction module (305) configured to control the contact indication threshold based, at least in part, on one or more time intervals between consecutive false wakeups.
