Abstract: A user interface apparatus, computer program, computer readable medium, and method for selecting a selectable object on a display screen is presented. The display screen displays one or more selectable objects. Information regarding a tracked hand position, and a tracked head or eye position of the user are obtained. Based on the tracked hand position and the tracked head or eye position, it is determined whether a said selectable object is located at a first screen position, the first screen position being a position on the display screen such that the first hand at least partly obscures the user's view of the selectable object. If it is determined as so located, then selectable object is determined as selected.

Abstract: This is a method and a system for animating on a screen (3, 3?, 3?) of a mobile apparatus (4, 4?, 4?) an avatar (2, 2?, 2?) furnished with a mouth (5, 5?) using an input sound signal (6) corresponding to the voice (7) of a speaker (8) having a telephone communication. The input sound signal is transformed in real time into an audio and video stream in which the movements of the mouth of the avatar are synchronized with the phonemes detected in said input sound signal, and the avatar is animated in a manner consistent with said signal by changes of posture and movements by analysing said signal, so that the avatar seems to talk in real time or substantially in real time instead of the speaker.
