Robertson ( Robertson, et al. 1998) developed the "Data Mountain" system. The system is a document management system using 3-D graphics technology. The system allows users to place icons representing the document on arbitrary positions in a 3-D desktop virtual environment. Users can access the document selecting the icon.
They evaluated the system comparing an existing WWW browser. Using "Data Mountain", the retrieval speed was higher, incorrect retrievals were fewer, and the failure retrievals in two minutes were less than when using an existing WWW browser. Above results revealed effects of 3-D GUI.
The system can display a lot of icons. But icons are overlapped and not categorized. Users have to move a mouse in every direction to select an icon. This manipulation needs a flat place on which the user can manipulate the mouse. So, the system fits a large-sized display using a mouse on a desktop.
On the other hand, using our system, icons move to the front of a display. Users do not have to move their eye points and hands too much when moving a switch on remote control. So, features of our system fit a small-sized display and remote control.
This paper described the internet browsing system using 3-D GUI. We have focused focusing on internet services for cars for which we developed the terminal. We realized a 10-square-centimeter size board that is compact enough for cars. We proposed the 3-D GUI and implemented it on the board. It works at a practical speed.
