Our navigation system "the inner GPS that helps us to find our way" integrates cues from multiple sources. We use objects in the environment as landmarks and also internal signals from the motor system and proprioception, providing information about body position and orientation in space.
We apply psychophysical methods and virtual reality techniques to find answers to the following questions: How do humans employ and combine different internal and external cues for homing? Is the quality of single sources considered and weighted for multisensory information processing? What is the origin of navigational errors? How do we deal with incomplete and erroneous navigational cues?
