Kinematic approach for the evaluation of human visual perceptibility in the workspace

This paper presents a new kinematic method to evaluate the human visual perceptibility in the workspace. The results of the method determine the regions of the workspace from which human visual system (HVS) has high quality images in most of the eye and neck postures. To evaluate the image quality of points in the HVS, motion perceptibility and acuity measures are defined and computed for the points that are in the focus range and field-of-view (FOV) of the observer. Motion perceptibility in the HVS is evaluated by applying a motion resolvability concept for the first time. The perceptibility measures are averaged over all the eye poses to determine the average visual perceptibility of the human workspace. The method is implemented on a subject with average body sizes, however, it can be easily adapted to different human subjects
