Increasing perceived value between human and robots — Measuring legibility in human aware navigation

Robots will more and more enter our daily life. In order to increase their acceptance it is necessary that their movements and behavior are predictable. With our present experiment we assess the acceptance of autonomous robots in human working and living environments. As a specific indicator we define legibility as an important prerequisite for user acceptance. In a simulator study participants rated the navigation behavior of a robot with regard to several aspects of legibility. Results show that Human Aware Navigation is a method to increase the perceived value of robot navigation behavior.
