Here, we investigated whether the influence of a tilted visual frame on the perception of the visual vertical can be modified in a virtual immersive environment by the structure of the visual scene and by the adjustment mode allowing visual or visuo-kinesthetic control. The observed influences may result from the dynamic combination between reference frames, which might occur and evolve throughout the subjective vertical adjustment. It is assumed that such effects may also express the level of presence of the physical observer immersed in a virtual environment.
