      In the information society of the 21st century, it is important that human beings comfortably coexist with information systems through visual human interface. To realize better human interface in next generation information systems, this paper proposes as a basic theory for human interface and communication a new type of size called Subjective Size which measures the apparent size of an object in relation to different viewing distances. In this paper, human interface means the bridge between the real world and imagery information space, which is the structure of information in human brains induced from the real world through human senses. We applied a psychophysical approach in estimating the relationship between subjective size (i.e., apparent size) and viewing distance by measuring the apparent size of an object in relation to viewing distances. For this, we measured the apparent size of an object from various viewing distances using discs and spheres as stimuli, and proposed a model that relates viewing distance to apparent size. Finally, we tested the validity of the model (i.e., Subjective Size Function) by an experiment that compared perspective images of real space through the subjective size function with actual images of real space.

      New varieties of tomatoes have been developed in Japan. High-sugar-content tomatoes present a target for improving the palatability of tomatoes. We evaluated the sensory attributes in relation to preference and acceptance of four kinds of tomatoes, two high-sugar-content tomatoes and two types of regular tomatoes. High-sugar-content tomatoes are visually attractive, have a strong flavor and are palatable in small quantities. However, if they are eaten in large quantities in daily meals they lose their appeal. When they are eaten in a salad, the palatability score is high but not always superior to that of regular tomatoes.

      Our past studies revealed that the effect of mere exposure that the novel stimulus object could make a favorable impression by the mere repeated exposure was seen in the dress photographs as stimulus objects. But it could be also thought that the effect is seen for the model's face itself in the dress photographs by the mere repeated exposure. Therefore, the purpose of this study is to verify that the effect is seen also for the dress itself. For the purpose of the verification, the experiment was made under two conditions of 1) stimulus photograph of the dress and 2) that of both the dress and the face. The result of the experiment was that no difference was seen in the sex of the subject, and no significance was seen in the condition of the photographs, either. Since, however, a favorable impression was increased at the 20 (twenty) times exposure, the effect of the mere exposure was surely seen also for the dress itself.
