When humans perform a simple grasping movement (e.g., when they pick-up a bottle) in different task contexts (e.g., with the intention to place the bottle at another location or to pour water into a glass), the respective grasping movement is adapted on-line to the task requirements and executed in a fast, precise and smooth way. We investigated whether and(More)
Today's manufacturing and assembly systems have to be flexible to adapt quickly to an increasing number and variety of products, and changing market volumes. To manage these dynamics, several production concepts (e.g., flexible, reconfigurable, changeable or autonomous manufacturing and assembly systems) were proposed and partly realized in the past years.(More)
Manual assembly conducted by skilled human workers is of outstanding relevance for flexible production with high precision. Nevertheless, due to capacity limitations humans need to be supported during the working process in order to reduce mental workload and for enhancement of performance. Cognitive technical systems are able to do so by adapting the(More)
When observers are asked to localize the peripheral position of a small probe with respect to the mid-position of a spatially extended comparison stimulus, they tend to judge the probe as being more peripheral than the mid-position of the comparison stimulus. This relative mislocalization seems to emerge from differences in absolute localization, that is(More)
In the Fröhlich effect, the perceived onset of a moving stimulus is displaced in the direction of motion. Previously, we observed that pointing movements produced a Fröhlich effect only when the onset position was highly predictable. Here, we show that relative judgments are not affected by spatial predictability if the relative judgment task is performed(More)
When observers pursue a moving target with their eyes, they use predictions of future target positions in order to keep the target within the fovea. It was suggested that these predictions of smooth pursuit (SP) eye movements are computed only from the visual feedback of the target characteristics. As a consequence, if the target vanishes unexpectedly, the(More)
