Abstract: Current mobile augmented reality off-screen visualization methods usually display the digital objects in the center of the screen.However,due to the limited screen size of a handle device,it would be intensive when there are many objects and thus have a low visualizing performance.To address this,we proposed an off-screen visualization method which utilized the edge of the screen to visualize many off-screen objects simultaneously.Based on geographical data and sensors,the method displayed arrows around the screen to indicate the directions and distances of off-screen objects,also a box whose size could be adaptive to the distance between the device and an in-screen building was designed for indicating the building,to increase the system performance.Experiments were conducted to compare the performance of the proposed method and the traditional method which displays the objects in the center of the screen.The results showed that the proposed method had a better performance in terms of locating buildings,with task completion time decreasing 11.02% and user satisfaction increasing 14.72%.
