Abstract

A method of effecting a communication event via a network between a requesting user, operating a first user device, and a responding user, operating a second user device comprises: initiating the communication event, in which each of the user devices captures a stream of audio data, transmits the captured stream of audio data to the other user device via the network for receiving thereat, and outputs, to its user, the audio stream received from the other user device; wherein a video exchange function is initially suppressed for the communication event for both of the user devices, by first and second video suppression components associated with the first and second user devices respectively, and the first user device transmits to the second user device, in response to a user input from the requesting user, a request to stop suppressing video for the communication event; and wherein if the responding user does not accept the request, both of the video suppression components continue suppressing the video exchange function for both of the user devices, wherein if the responding user accepts the request, both of the video suppression components stop suppressing the video exchange function for both of the user devices in response, wherein each of the user devices implements the video exchange function by capturing a stream of video data, transmitting the captured stream of video data to the other user device via the network for receiving thereat, and displaying, to its user, the stream of video data received from the other user device.

Abstract

A computer-implemented method of rendering a user interface, the method comprising the following steps: at a user interface controller, receiving visual content to be displayed on a display of a user device, wherein the user interface controller generates obfuscation data for obscuring the visual content and controls the display to render a user interface on which the visual content is obscured according to the obfuscation data; and transmitting, from the user device to a remote device, a request to stop obscuring the visual content, wherein the request is transmitted in response to a drag gesture detected at the user device; wherein as the drag gesture is performed, the user interface controller responds by modifying the obfuscation data to reduce a level of obfuscation applied to the visual content before the request has been accepted, whereby the visual content remains obscured but with a lower level of obfuscation, wherein if the request is subsequently accepted at the remote device, in response the user interface controller controls the display to stop obscuring the visual content, thereby rendering it fully visible on the display.
