This paper investigates effects of the color of oshibori on thermal sensation in the hands. We conducted a subjective evaluation experiment concerned with the temperature of oshibori using the method of paired comparisons. We employed 13 different colors of oshibori; one white oshibori and twelve colored oshibori (six hues (4R, 8YR, 5Y, 3G, 5B, and 7P) × two tones (pale and vivid)), in the experiment. Temperature of the white oshibori was set at 50 degrees C and that of the color oshibori was set at various temperatures from 44 to 56 degrees C. We obtained the temperature at which the selection rate of the answer became 50 % and defined as the point of subjective isothermal. As a result, the pale red oshibori was felt 0.77 degrees C hotter than the white oshibori, and the vivid blue oshibori was felt 0.95 degrees C colder than the white oshibori.

With recent advances in high dynamic range displays, high-gradation displays have been actively studied. The suitable gradation number for a luminance range of a display is not obvious. We had researched about the relationship between the gradation number and the displayed image to find the suitable gradation number for the luminance range of a usual display. We found if the gradation area of the displayed image was more than 50%, the gradation number more than 8 bit was suitable. However, if it is less than 50%, we could not tell any effects of increasing the gradation number.

Our aim is to develop an AR device which can grab a virtual object with a close sense of the real world. In our research, we focus on grabbing a virtual object with bear hands and on interaction with the virtual object in the three-dimensional coordinate system. In addition, we conduct hidden surface removal between user's hands and the virtual object when the user interacts with the virtual object in order not to occur visual contradiction.

Use of stereoscopic 3DCG (S3DCG) is increasing in movies, games and animations. However, a method for objectively evaluating production capability has not been established. If possible to measure the production capability on basis of certain criteria, unified evaluation can be useful at school. In addition, it is useful to human resource development and adoption of enterprise. Therefore, the experiment conducted practical tests using 3DCG software to making a scene of S3DCG. The practical tests were carried out before and after subjects learning. As a result, it was able to measure improvement of subject's capability after learning, and the difference in capability between subjects. In this paper, we will report on the experimental method and results.
