The present invention is the invention for providing a guidance service by using a robot. For example, the robot may provide the guidance service in an airport. The robot may receive a destination, acquire a movement path from a current position to the destination, and transmit the movement path to the mobile terminal. The mobile terminal may receive the movement path from the robot and display a guidance path representing a movement path and a user path representing a position movement of the mobile terminal and overlapping the guidance path.

The present disclosure relates to an automatic volume adjustment method and apparatus, a medium, and a device, which belong to the field of computer technologies, and can adjust the playback volume of audio or video. The automatic volume adjustment method includes: acquiring, in a case that a terminal does not output loudspeaker sound, a noise signal outside the terminal; determining noise energy based on the noise signal; and adjusting playback volume of audio or video on the terminal based on the noise energy.

An electronic device is provided. The electronic device includes a display, a camera, and a processor. The processor displays a first image obtained through the camera, displays, in response to the first image being enlarged in one magnification in a designated first magnification range, the enlarged first image as a second image, displays, in a designated area of the display, a guide map including a first guide box indicating a location of the second image and having a size which varies in response to a magnification change in the first magnification range, and when the first image or the second image is enlarged to a third image in response to the first or second image being enlarged by one magnification in a designated second magnification range greater than the first magnification range, changes the first guide box to a second guide box having a fixed size.

The present disclosure refers to apparatuses and methods for initializing electronic devices. An electronic device according to various embodiments includes a memory, and a processor operatively connected to the memory. The processor is configured to record, in the memory, software binaries received from an external device during a download mode. The processor is further configured to, when the download mode has ended, perform booting in a normal mode using a bootloader based on a determination indicating that a predetermined software binary is present among the software binaries recorded in the memory, and perform booting in a recovery mode using the bootloader based on the determination indicating that the predetermined software binary is absent from among the software binaries recorded in the memory.

Provided in embodiments of the disclosure are a folding terminal control method and apparatus, a terminal and a storage medium. A folding terminal is provided with a first display area and a second display area, and an included angle between the first display area and the second display area changes along with folding or unfolding of the folding terminal. The folding terminal control method includes: responding to an unfolding operation, opening at least one second application different from a first application in the second display area, wherein the first application is an application which is running by the folding terminal before responding to the unfolding operation, and the second application can be quickly called by changing unfolding and folding postures of the folding terminal, thereby improving the interactive use experience of a user.

An information processing apparatus including a touch panel and a near field communication interface. The information processing apparatus detects that an input received at the touch panel corresponds to a predetermined input when the information processing apparatus is in a suspended state; and controls the information processing apparatus execute a predetermined function via the near field communication interface and awake from the suspended state upon detecting that the input corresponds to the predetermined input.
