Effects of ageing and sound on perceived timing of human interactions

Variations in the timing and speed of movements in human interactions carry important social information. For example, seeing one player push another player at a football game, we can deduce whether the player being pushed resisted or anticipated the oncoming push based on subtle differences in the timing and velocity of movements of both players. With the development of computer animations of human characters, it is important to understand the sensitivity and limits of human perception in such interactions to accurately portray human interactions.
