Empirical Evaluation of Throwing Method to Move Object for Long Distance in 3D Information Space on Mobile Device

摘要

In our previous work, a throwing method to move an object for long distance in 3D information space on a mobile device was proposed. With the method, as we throw the object to move it far away in the real world, we can throw the virtual object in 3D information space. This simple throwing method was improved by adding following three functions. They were real time adjusting the direction of moving object, moving viewpoint to follow the thrown object, and initializing viewpoint after the movement. The purpose of this paper is to examine the performance of the improved throwing method to move the object for long distance in 3D information space. From the experiment, it is found that the improved throwing method is efficient to move the object for long distance in 3D information space on mobile devices.
