            Abstract : 
The paper presents an information compressing 3-dimensional user interface on the support system of requirement extraction from a BBS (Bulletin Board System). To correspond to users´ viewpoints, the Fish-Eye is applied. With the Fish-Eye, a size of an object on the output screen is decided according to the user´s attention. This function is realized in topic groups, opinion cards and text in cards respectively. A way of applying Fish-Eye with regards to the topic groups and opinion cards is to show the objects on the inclined coordinates from viewpoints. To realize the Fish-Eye for letters, the priority is set on each sentence in the opinion. The priority is decided from the character of conversational structure, which has a tree structure. With this structure, the attention of the user is specified and is reflected in selecting which sentences should be written in the opinion cards
