One communication device includes a memory storing a software application, an electronic processor, a mechanical interface receiving a first user input, and a touch screen receiving a second user input. The touch screen is also configured to display an output generated by the software application. The electronic processor is configured to execute a software application stored in the memory, determine when the second user input is received simultaneously with the first user input, perform a first action based on the first user input when the second user input is not received simultaneously with the first user input, the first action being unrelated to operation of the software application, and perform a second action based on the first user input when the second user input is received simultaneously with the first user input, the second action relating to the operation of the software application.

This application relates to the field of electronic technologies, and provides a task switching method and a terminal to reduce user operations in task switching, improve human-machine interaction performance, and improve user experience. A specific solution includes: displaying, by a terminal with a sensor installed on a side edge, a first interface in response to a pressing operation of a user on the side edge, where the first interface includes at least one task window; detecting a sliding operation of the user on the side edge, where the sliding operation and the pressing operation are continuous operations of a finger without leaving the side edge; displaying a first task window in a preset manner in response to the sliding operation, where as a sliding position of the sliding operation changes, when the at least one task window includes a plurality of task windows, the first task window displayed in the preset manner is switched in the plurality of task windows; and displaying a second interface in response to detecting that the sliding operation is ended and that the finger of the user leaves the side edge, where the second interface is an interface of a task corresponding to the first task window displayed by the terminal in the preset manner when the sliding operation is ended and the finger of the user leaves the side edge.

A mobile terminal includes a terminal body, a metal case forming an appearance of the terminal body and including a side region and a second region integrally formed with the side region and supporting the inside of the terminal body, and a rear molding part formed in a region of the metal caser. The rear molding part includes a first molding region formed to have a closed loop shape along an inner surface of the side region and a second molding region extending from the first molding region and forming a receiving space for receiving at least one electronic component. The side region includes a plurality of opening holes, and the first molding region is formed to cover the plurality of opening holes.

Disclosed are devices, systems, methods, and media for efficient emergency calling using digital devices. In some embodiments, a user is able to make an emergency call by a one-touch or dual-touch process. An authentication process may reduce inadvertent and unauthorized emergency calling. Persistent emergency buttons are also disclosed that may be used for calling emergency in different states of the device.

A touch control auxiliary apparatus, protective casing, touch screen and mobile terminal. The touch control auxiliary apparatus comprises: a main body having a touch screen contact surface and a finger sliding surface; a plurality of control lines insulated from one another, the plurality of control lines are in the main body, orthogonal projections of the plurality of control lines onto the touch screen contact surface are parallel to one another, the plurality of control lines are in a same plane, and the plane where the plurality of control lines are located is not coplanar with the finger sliding surface; and a plurality of touch lines insulated from one another, wherein the plurality of touch lines are in the finger sliding surface and the plurality of touch lines are parallel to one another, and the plurality of touch lines are connected to the plurality of control lines in a one-to-one correspondence.

A mobile terminal including a terminal body; an ultrasonic sensing unit mounted on at least one side surface of the terminal body and configured to generate an ultrasonic wave on a path propagating along the at least one side surface of the terminal body; and a detecting circuit configured to detect a touch applied to the terminal body by using a signal change caused due to a touch on the path of the ultrasonic wave.

The present disclosure generally relates to user interfaces for managing input mechanisms. In some examples, the electronic device transitions from a first mode into a second mode in accordance with a determination that the one or more characteristics of a user input detected via a second input mechanism of the electronic device meet a set of predefined criteria. In the first mode, a first input mechanism of the electronic device is disabled for user input. In the second mode, the first input mechanism of the electronic device is enabled for user input.
