In four-sided CAVE systems, the absence of rear wall has been shown to decrease the level of immersion and can introduce breaks in presence. With this experiment we analyse how user attention is diverted while walking in VE when audio and/or visual attractors are present. Auditory feedback was delivered through binaural audio. The CAVE used for the experiment allowed users to walk up to 9m in straight line. \ Different ???attractors??� were proposed (audio and/or visual, static or dynamic). Results show that audio-visual attractors are the most efficient in order to keep the user???s attention toward the inside of CAVE.
