ABSTRACT
AR navigation has been widely used in mobile devices. However, users sometimes immerse in the navigation interface and ignore probable dangers in the real environment. It is necessary to remind users of potential dangers and avoid accidents. Most of existing works focus on how to effectively guide users in AR but few concern about design of danger reminder. In this paper, we build a virtual AR navigation system and compare user experience on different types of obstacle reminder. Furthermore, we compare the influence of color, motion and appearance distance on effectiveness of the reminder. Results show that red color and bi-color are more obvious than blue color for reminder. Motion such as flickering effect helps enhance remind effectiveness.

Obstacle-Aided Navigation of a Soft Growing Robot
2018 IEEE International Conference on Robotics and Automation (ICRA)For many types of robots, avoiding obstacles is necessary to prevent damage to the robot and environment. As a result, obstacle avoidance has historically been an important problem in robot path planning and control. Soft robots represent a paradigm shift ...
