| Abstract | Nowadays Thailand government has been proposed the aTOP project to promote various products of Thailand. Due to the several kinds of products, visualization was developed to help buyers easier search desired products. In this study, MDS was employed to map the criteria of OTPO products on 2D. According to reviewing of literatures, four techniques of visualization were applied: original layout of MDS, price orientation on y axis of original layout, no overlapping layout and price orientation on y axis of no overlapping layout. First, in original layout of MDS, the positions of pictures were directly calculated, and the pictures were displayed at those calculation points. However, since most of buyers more pay attention on products prices, the second techniques, price orientation on y axis of original layout, was established. The products were arranged as their prices along y axis. Unfortunately, both techniques which displayed each item in terms of a picture, confronted the problem of picture overlapping. Therefore, the other technique was used with th.e help of algorithm to eliminate the picture overlapping and place all items within a screen. For the last technique, it was developed from the former one and included the importance of product prices. The overlapping of the pictures was solved with the proximity grid idea. The screen was divided as numerous small cells which each cell was reserved for only one picture. These four techniques were evaluated by users, and most of them prefer the last one. The items were arranged by price, but were not directly sorted; therefore, the prices were not arranged in ordinal. However, the advantages of the last technique were that buyers can view all items without zooming and panning including briefly price ranges |
