Systems, methods, and computer program products are provided for improving establishment and broadcasting of communication among mobile computing devices. For example, a method comprises determining a first user accesses a mobile application on a first mobile device of the first user; determining a second user accesses the mobile application on a second mobile device of the second user; and initiating the audio conversation between the first user and the second user, wherein the audio conversation is streamed to a third user who accesses the mobile application on a third mobile device of the third user.

A camera system for generating an eye contact image view of a person with a gaze direction that is offset from a camera position, the camera system includes a camera configured to obtain image data of the person, a processing circuitry configured to be operatively connected to the camera and configured to obtain a camera view of the person from a camera position, and generate a synthetic camera view of the person from a virtual camera position.

An interface display method and apparatus, and an electronic device are disclosed. The interface display method includes: displaying, by an interface display apparatus, a target window, where the target window includes N payment identifiers, each payment identifier indicates one payment interface in one target application, and N is a positive integer; receiving, by the interface display apparatus, a secure input of a user; and in a case that security information corresponding to the secure input matches preset security information, displaying, by the interface display apparatus in response to the secure input, a payment interface indicated by a target payment identifier in the N payment identifiers.

A method of controlling a display device includes the steps of displaying a first image in a first size on a display surface, displaying the first image and a second image which has the first size and is different from the first image on the display surface when an operation of changing a size of the first image is started, displaying the first image in the first size on the display surface when the operation continues, displaying the second image in a size different from the first size on the display surface based on the operation when the operation continues, and displaying the first image in a second size based on the operation on the display surface when the operation terminates.

A display control unit sets a first virtual region around a display region of a display, sets, as a second virtual region, a region which is a part of the display region and which does not display information shared with a terminal of a communication partner in order to match an aspect ratio with that of the terminal of the communication partner, in a case where it is determined that a part of a character string protrudes from the display region, extends a curve to any one of the first virtual region, the second virtual region, and the first virtual region straddling the second virtual region, and generates display information in which the part of the character string is disposed along the extended curve in any one of the first virtual region, the second virtual region, and the first virtual region straddling the second virtual region.

An information processing apparatus includes a processor configured to: display a representative image representing a document file shared by plural users on a screen of a terminal apparatus of a user, a single representative image being prepared for a single document file; and in a case where another user is viewing or editing the document file, display information indicative of the other user and information indicative of a part of the document file which the other user is viewing or editing while displaying the representative image.
