项目摘要

The aim of this research is to find out an intuitive interaction method using mobile devices. For that purpose, this research focuses on finding the suitable mapping between the input action with the portable information terminal (PIT) in the real world and the operation in the 3D information space.From the experiments, it was found that each primitive operation was mapped to some actions respectively. However, for practical operation in the 3D environment, multiple primitive operations are done concurrently. Furthermore, because users must select the object before move or rotate it, moving or rotating operation must follow the selecting operation. That is, the input action for selecting depends on the input action for moving or rotating. With taking into account of this concurrency and dependence, the suitable mapping between the operations in the 3D information space and the actions in the real world are followings; (1) changing the view position with changing PIT position, (2) changing the view orientation with changing PIT orientation, (3) selecting and moving the object with picking or grasping the object and moving the hand, and (4) selecting and rotating the object with picking or grasping the object and rotating the hand.However, in order to move the object far away, it caused a physical fatigue to the user or decreased the task performance because he/she should move the mobile device or his/her hand widely. To overcome this problem, the object moving method with throwing gesture, named as "throwing method", is also proposed in this research. With the proposed method, users can not only throw the object but also adjust the direction of the moving object as they want. From the experiment, it is found that the proposed method reduces the physical fatigue of the user and might be possible to increase the task performance.

这项研究的目的是使用移动设备找到一种直观的交互方法。为此，本研究的重点是在现实世界中使用便携式信息终端（PIT）与3D信息空间中的操作找到合适的映射。从实验中，发现每个原始操作分别映射到某些动作。但是，对于3D环境中的实际操作，可以同时完成多个原始操作。此外，由于用户必须在移动或旋转之前选择对象，因此移动或旋转操作必须遵循选择操作。也就是说，选择的输入动作取决于移动或旋转的输入动作。考虑到这种并发性和依赖性，3D信息空间中的操作与现实世界中的行动之间的合适映射是遵循的；（1）随着凹坑位置的变化更改视图位置，（2）随着凹坑取向改变视图方向，（3）选择和移动物体，通过拾取或抓住或抓住对象并移动对象并移动手并移动手，以及（4）选择和旋转对象，通过拾起或抓住对象或旋转手动并旋转对象。他/她的手广泛。为了克服这个问题，在这项研究中还提出了用抛出手势的对象移动方法，称为“投掷方法”。使用提出的方法，用户不仅可以抛出对象，还可以根据需要调整移动对象的方向。从实验中可以发现，提出的方法减少了用户的物理疲劳，并且可能会增加任务性能。
