Methods, systems, apparatuses, and media for pressure sensing for user interactions are disclosed herein. In some implementations, a method involves obtaining sensor data from one or more sensors disposed proximate to an enclosure of a capsule of a wrist-worn device. In some implementations, the method involves determining, based on the sensor data, that a press interaction has occurred. In some implementations, the method involves determining, based on the sensor data, force characteristics associated with the press interaction. In some implementations, the method involves identifying a press type of a plurality of press types based on the force characteristics. In some implementations, the method involves identifying an operations of the wrist-worn device from a plurality of operations based on the press type. In some implementations, the method involves causing the identified operation to be performed by the wrist-worn device.

Pressure sensing for user interactions

Systems, methods, and computer-readable media are disclosed for haptic feedback devices with reduced power consumption. In one embodiment, an example device may include a first spring, a mass coupled to the first spring, and a resonant piezoelectric actuator coupled to the first spring. The resonant piezoelectric actuator may be configured to impart a force on the mass via the first spring responsive to an applied voltage. The device may include a power source configured to supply the applied voltage to the resonant piezoelectric actuator, where motion of the mass generates vibration.
