The Influence of Multimodally Specified Effort on Distance Perception
This research investigated the contributions of two different sensory modalities (kinesthesis and vision) to the perception of one aspect of environmental layout, distance. In order to address this issue, the two sensory modalities were de-coupled by using a virtual reality treadmill environment to evaluate their respective influence on multimodal distance perception. Previous visual-motor recalibration experiments have demonstrated that that a change in perceived self movement can be manipulated by the relation between the speed of optic flow in relation to the treadmill speed. This research used a similar methodology to show that perception of distance is proportional to multimodally specified effort (MSE) – the actual effort (measured in cal) required to walk an optically specified distance (m) – and that distance perception is insensitive to the mode of manipulation of MSE.
