      Product concept sentences express effectively the characteristic images of products to communicate with the user's images. In this study, it was found first that users couldn't recognize such images from the existent concept sentences. We noticed that the characteristic image of each product, expressed by concept sentences, changes according to the noun after the adjective, even if the adjective is the same word. Therefore, we have developed an analysis method of their characteristic images from text typed-data such as concept sentences, which is called the ‘Product image analysis method.’ In the procedure of this analysis method, “adjective+noun” units as image words are collected and arranged. Next, the units are classified, paying attention to the meanings of the nouns in the units. In this way, the classifiers understand the elements of product images expressed by the units. By this procedure, 8 categories with characteristic images of cars have been extracted from their concept sentences as samples. Further, based on these results, we have obtained the findings about the composition technique of concept sentences. Finally, the practical application of the ‘Product image analysis method’ has been confirmed from these obtained results.

      This study investigated the effect of character size on the legibility of sentences, using reading materials with several font sizes (from 4 to 10.5 point of Microsoft Mincho). Participants evaluated the legibility of the materials (Japanese sentences) with a questionnaire containing 13 items, and the legibility was estimated by applying the Item Response Theory to the questionnaire data. The legibility increased approximately in linear with the font size : Reading materials with font sizes of 4 and 6 were evaluated as less legible, those with font size of 10.5 were evaluated as more legible, and those with a font size of 8 were evaluated as “neutral”. Visual acuity of participants influenced the legibility evaluation, though the effect was small.
