Design and a technique of URUSHI(Japanese Lacquer) craft were run by the division of labor system in the Edo era, the URUSHI craft was the high media in the design expression. After the Meiji Restoration, among the modernization and internationalization of the society, the entire craft, including URUSHI were clearly positioned in the lower to fine art by international and political factors. Craftsman aimed at reinstatement as artistic expression left the division of labor system and started the behavior as a personal artist. Due to the effect of the change in the post-war lifestyle, lacquer technique is no longer utilized in daily products. In the process of lacquer technology is highly pure and sophisticated as artistic expression, the understanding of URUSHI in general has decreased. While mechanization is not almost introduced in URUSHI, there are plenty room that can be replaced or updated by the modern digital technology through reviewing the process. This report shows the possibility of URUSHI as a modern media in the design expression through reinterpreting URUSHI technique by digital fabrication.

In this paper, we propose "ExtensionSticker", a striped pattern sticker that can extend touch interface by simply attaching the sticker to a touch panel display. This sticker has multiple conductive lines, and when the user touches on the sticker, a touch input can be generated. This method is not only touch input as specific locations, but allows for continuous touch input such as scrolling operation. This allows a user to prototype an interface to extend touch panel devices easily. Furthermore, we experimented on the recognition accuracy of scroll and tap actions using the proposed method.

This paper analyzes the relationship between digital fabrication and fandom learning represented in ethnographic case studies of six informants aged 21-24 participating in common-based peer production group, a craftwork group in a college. Learning as digital fabrication and social fabrication is a new wave culture of mavens, who are devoted to an alternative to mass production and the mission of "how to make (almost) anything". In addition, craftwork (especially, "Costume Play") with digital fabricators is a valuable venue for observing about, for example, appropriation, boundary crossing, poaching, and so on. First we frame this work as an effort to think about their making and learning using the concept of "appropriation" [20] from Wertch. Then we share an overview of Cosplay in "Fab society" in Japan, in particular our methodology based on shadowing and participant observation. Using Tsuchikura's methodology[18], we group our findings in three different categories: (1) learning as appropriation of meanings of new technologies, (2) appropriation of waiting time and (3) learning from and taking interest in cross-cultural practices through participation in local and small fandom group.

We propose a design method that processes the surface of Urushi, a Japanese traditional coating material, with computer technology and ultraviolet (UV) light control. Urushi changes their physical condition by absorbing UV light energy. Our research introduces design method with this physical feature for digital fabrication. Our contribution is to realize imprinting method on urushi coated surface with computerdesigned pattern. We use two methods to control of the light. One method is laser method that uses laser and galvanomirror. The other one is mask method that uses a lamp and mask pattern. We introduce suitable material and procedure for these methods, and demonstrate the potential of them.

In recent automotive display systems, a method of presenting the displayed information collated with the forward view, as typified by navigation systems, is becoming a key technique. Below is called "Indicating-Type Display". In visual optical experiment using "Indicating-Type Display", we verified reaction time by changing difference in viewing angles between the area of the displayed images and the forward view. Preceding studies have explained that reaction time of "Indicating-Type Display" mainly stems from the driver's eye movements and accommodation. However, preceding studies is insufficient to explain This experimental results. We have introduced a new cognitive model, called "Mental Zooming", focusing on the difference in viewing angles between the area of the displayed images and the forward view. And from the model,We demonstrated that Automotive Augmented Reality Interface System (ARIS) is superior to other automotive display systems in terms of faster recognition of the information displayed.

Information about the nature and characteristics of streets is useful to strolling tourists. This paper describes the Kansei stroll map that visualizes streetscape impressions. Subjective evaluation experiments firstly quantified the impressions of streetscapes in the city of Kyoto. The impressions from around the city were then visualized using colour and colour density by employing the Kansei structure visualization technique, proposed by the present authors. Each visualization result was combined with a map and the Kansei stroll map was finally implemented on PCs. User studies with eight participants examined its use both in planning routes and walking in the city. The studies suggest that the visualized impressions provided by the stroll map help users to find less-known places and streets that match their interests.

This paper proposes a caution system for the following two purposes: (1) inferring driver intentions to change lanes, and (2) issuing caution messages when the driver seems distracted. The idea of our method is that, when the driver is not distracted, driver intent to change lanes can be found via analyzing driver eye movement based on a model of driver behavior to check the side-view mirror for preparation of a lane change. If, on the other hand, the driver is distracted, the system fails to detect the intent even when the traffic environment suggests that the driver may want to change lanes. The results of a cognitive experiment showed that a caution system is effective to prevent the deterioration of the checking behaviors and to relieve the risk of a collision to the slow lead vehicle at the initiations of changing lanes.
