Abstract: A three-dimensional touch sensor and a display device are provided. The three-dimensional touch sensor determines a position of a touch force by a first capacitance formed by the pressure receiving electrodes and the transmitting electrodes, and determines a magnitude of the touch force by a second capacitance formed between the pressure receiving electrode and the pressure sensing electrode. Therefore, not only the position of the touch force but also the magnitude of the touch force can be determined. Synchronous sensing of the position and the magnitude of the touch force is achieved, which is beneficial to human-computer interaction.

Abstract: An electronic device with a first off-display input region detects a first portion of an input on the input region. In response to the first portion of the input: when the first portion of the input meets first criteria without a characteristic intensity of the first input increasing above a first intensity threshold, the electronic device provides a first output that indicates a current state of a first attribute of the electronic device without altering the first attribute. The electronic device detects a second portion of the input. In response to the second portion of the input: if the second portion of the first input meets second criteria that require the characteristic intensity of the input increases above the first intensity threshold, the electronic device performs a first operation that alters the first attribute of the electronic device; and otherwise, the electronic device forgoes performing the first operation.

Abstract: The present disclosure relates to techniques accessing and displaying information pertaining to past times and future times. In some embodiments, a device displays a first current-time indicator and a user interface object configured to display information corresponding to a first information source and to the current time. In some embodiments, in response to and in accordance with detecting a rotation of a rotatable input mechanism, the device displays a non-current-time indicator indicating a non-current time, and updates the first user interface object to display information corresponding to the first information source and the non-current time. In some embodiments, the device continues to display an indication of the current time.

Abstract: An elongated stylus is configured to be capacitively coupled with a sensor array providing a plurality of electrodes to indicate a position on the sensor array. The stylus includes a housing having an end in an elongated direction of the housing, a conductive tip disposed at least partially extended from the end of the housing, an electrode disposed around the conductive tip and configured to at least partially expose the conductive tip, and a signal transmit drive circuit configured to provide a signal. Control is performed to form an electrical connection between the electrode and a ground and an electrical connection between the electrode and the signal transmit drive circuit when the elongated stylus is activated for capacitive coupling with the sensor array.
