◎Background & Purpose

Visualization in the VR Environment has several advantages.

・Walkthough in dataset with immersive experience．
・Use of depth to sort items．

thus!! It is useful for data analysis or management as well as comprehensive data presentation. But, if you handle a spherically organized data as shown in Fig.1 , you may handle it directly , intuitively.

For instance,
・rotation along arbitrary axis
・access at the same time
・selection of data in arbitrary area

Fig1spherically organized data [Spherically Self-Organiging Map]

◎Hemisphere-shaped interface

This interface provides both display and input functionalities.

・the device uses a miniature hemisphered- shaped plastic screen.
・Finger movement can be extracted as input.
・Thermal image of fingers on the screen is captured.

＜System＞
The proposed system is shown in Fig2.

◎Implementation

Intuitive operation using thermal image is implemented.

1．Rotation along arbitrary axis 　

2．access many points at the same time 　

3．Selection of data in arbitrary area 　

A prototype interface is shown in Fig3
