Motion Compression
Motion Cueing must balance the often conflicting needs of plausible perception of a simulated motion with the physical motion limits which constrain all simulators. To understand which combination of stimuli provided by the simulator will be properly interpreted by the subject, an understanding of self-motion perception is required. Human self-motion perception involves the contribution of different sensory systems and central mechanisms: the visual, vestibular, tactile and kinesthetic sensors along with brainstem and higher cortical processing. To characterize this complex perceptual process, we need to understand how the integration of these different sources of information, often discrepant, leads to the subjective representation of physical motion. A combination of experiments and advancements in self-motion perception modeling is built to systematically understand the role of the various cues, as well as cognitive influence on perceptual thresholds. We derive a range of different parameters and tuning algorithms for the motion cueing filters of our CyberMotion Simulator (see figure 3) and we study how they influence the perceived realism of simulated driving or flying tasks.
Perceived realism in motion simulation
- Fig. 3: View into the MPI CyberMotion simulator cabin. A complete driving interface with force-feedback steering wheel and pedals (bottom right in the picture) can be installed in it. The virtual environment can be displayed in mono or stereo on the white painted inner surface of the cabin hood.
Motion-based simulation necessarily has a limited physical workspace (figure 3). One method to perceptually expand the workspace is to use perceptual tricks, such as to simulate sustained linear acceleration by a combination of translation and tilt below the subjects’ vestibular threshold (so-called tilt-coordination). The tuning of the tilt/translation ratio is often done empirically, without considering the variability of perceptual thresholds. We measure vestibular perceptual thresholds in conditions that closely resemble typical vehicle simulation to determine how different sensory and cognitive factors contribute to the sensation of realistic motion. Several experiments are built to systematically address the influence of visual and vestibular cues, as well as cognitive workload on perceptual thresholds. We derive then a range of different parameters for the motion cueing filters and we study how they influence the perceived realism of tasks, such as slalom driving. Knowing the relative contribution of the different sensory components will lead to optimized tuning of the motion filters, enhancing the realism of the simulation.
