Important factors in mobile robot user interface design

In this study, four factors are considered to be important in the interactions between a mobile robot and a human. These factors are robot location, user's prior knowledge about the robot's environment, spatial reasoning ability of the user, and user interfaces. The first objective of this study is to determine if providing a user interface component showing the relative position of the robot with respect to the user results in any improvement. The second objective is to have an overall evaluation of the user interface components
