Abstract

There are described computer-implemented methods of obtaining a user input. A first such method comprises: (a) providing access to video content, the video content representing a user interface including a plurality of elements for selection by a user; (b) playing a first portion of the video content to the user; (c) detecting a first user interaction occurring in response to the played first portion of the video content; and (d) determining a first element selected by the user based on one or more properties of the detected first user interaction. A second such method comprises: (a) providing access to one or more frames of pre-generated video content encoded in compressed video format; (b) displaying to a user initial video content encoded in compressed video format, the initial video content being based on one or more frames of the pre-generated video content, and the initial video content representing a plurality of graphical elements for selection by a user; (c) detecting a first user interaction occurring in response to the displayed initial video content; (d) determining a first graphical element selected by the user based on one or more properties of the detected first user interaction; (e) in response to the first user interaction, generating new video content encoded in compressed video format based on one or more frames of the pre-generated video content and the one or more properties of the first user interaction; and (f) displaying the new video content to the user. There are also described corresponding apparatuses, computer programs, and computer-readable media.
