Tangible interface can be understood as a newly defined concept, which can provide an effective and seamless interaction between the human as a subjective existence and the cyberspace as an objective existence. Tactile sensation is essential for many exploration and manipulation tasks in the tangible space. In this paper, we suggest the design of an integrated tactile sensor-display system that provides both of sensing and feedback with kinesthetic force, pressure distribution, vibration and slip/stretch. A new tactile sensor with PDVF strips and display system with bimorph actuators has been developed and integrated by developed signal processing algorithm. In the scenario of haptic navigation in the tangible space, tactile feedback system is successfully experimented.

This paper presents a novel approach to design evaluation of portable consumer electronic (PCE) products using augmented reality (AR) based tangible interaction and functional behavior simulation. In the approach, the realistic visualization is acquired by overlaying the rendered image of a PCE product on the real world environment in real-time using computer vision based augmented reality. For tangible user interaction in an AR environment, the user creates input events by touching specified regions of the product-type tangible object with the pointer-type tangible object. For functional behavior simulation, we adopt state transition methodology to capture the functional behavior of the product into a markup language-based information model, and build a finite state machine (FSM) to controls the transition between states of the product based on the information model. The FSM is combined with AR-based tangible objects whose operation in the AR environment facilitates the realistic visualization and functional simulation of the product, and thus realizes faster product design and development. Based on the proposed approach, a product design evaluation system has been developed and applied for the design evaluation of various PCE products with highly encouraging feedbacks from users.

The purpose of this study was to investigate the influences of tangible clues on university students' perceived risks and satisfaction at family-restaurants in Seoul. The performances of 3 tangible clues(physical evidence, employee, service process) negatively influenced the student's perceived risks. This result indicated that tangible clues can reduce the negative characteristics of service (intangibility, inseparability, perishability and variability) toward student customers at family restaurants. Meanwhile, financial risk, performance risk and social risk negatively influenced their overall satisfaction. Performance risk had the strongest negative influence on student customers' overall satisfaction, indicating that university students were much more interested in performance and utility about menu, food and service quality than in other factors at family restaurants. As a result, food-service corporations need to manage suitably various tangible clues as an important marketing strategy to diminish their customers' perceived risk and raise their satisfaction.

Background and objective: Understanding abstract art as an art form requires depth of thought. Moreover, understanding land art as abstract art is challenging, given its focus on the minimalism and abstract concepts. Much focus, research, and work were actively conducted in the 1970s, as it represented an abstract expression of minimalism. The characteristics of minimalism connote abstract meanings in the use of materials. Nevertheless, the original research of works or artists has often been mentioned, but few studies have analyzed the abstract language of land art materials. The aim of this study is to thus determine the abstract meanings of materials in land art from the 1970s to the 2010s. Methods: Art-based research was employed to address the aim. This study classified the land art materials into intangible and tangible materials, where intangible materials focused on lines, circles, and labyrinths, and tangible materials focused on the earth, stones, wood, and snow. Results: Intangible and tangible materials of land art conveyed various abstract meanings. Intangible materials were reflective of connection and symbiosis with nature, delivering abstract languages of 'take-nothing,' 'reflection' and 'opportunity.' Tangible materials reflected the abstract concepts of 'intervention,' 'resistance,' 'unliving,' and 'change,' and conveyed caveats. In other words, taken together, intangible and tangible materials were presented in symbiosis-and with caveats-and delivered messages for the present and the future. Interestingly, intangible materials inherently reflect symbiosis and communicate caveats in works based on a non-contextualized present and future. Conclusion: Interpretation of the abstract languages derived from intangible and tangible materials could imply a symbiosis between humans and nature, while conveying the message that caveats, to humans, are still ongoing. This relationship plays a significant role in an artist's selection of a medium, which is reflective of abstract beliefs reflected in contemporary, nature-based works created on Earth.

This study utilized importance and performance analysis (IPA) in order to improve and plan tangible (menu) and intangible (service) products at dumpling shops. Menu attributes for tangible products were classified into sensory factor, health factor, hygiene factor, and external factor. Attributes for intangible products were classified into response factor, visual factor, spatial factor, package factor, and promotion factor. In IPA analysis of tangible products, sensory factor and hygiene factor were located in Quadrant I (Keep up the good work). Health factor was located in Quadrant III (Low priority for management) and the external factor was located in Quadrant II (Possible overkill). In IPA analysis of intangible products, response factor and visual factor were located in Quadrant I, whereas promotion factor was located in Quadrant III. The attributes related to kindness of staff and space for customers in the store were more important, but due to their low performance level, they were located in Quadrant IV (Concentrate management here). Thus, the product planner should improve attributes of the related product immediately. As a result, the development of competitive products within the market is possible.

In this paper, we present multi-sensor data fusion for telematics application. Successful telematics can be realized through the integration of navigation and spatial information. The well-determined acquisition of vehicle's position plays a vital role in application service. The development of GPS is used to provide the navigation data, but the performance is limited in areas where poor satellite visibility environment exists. Hence, multi-sensor fusion including IMU (Inertial Measurement Unit), GPS(Global Positioning System), and DMI (Distance Measurement Indicator) is required to provide the vehicle's position to service provider and driver behind the wheel. The multi-sensor fusion is implemented via algorithm based on Kalman filtering technique. Navigation accuracy can be enhanced using this filtering approach. For the verification of fusion approach, land vehicle test was performed and the results were discussed. Results showed that the horizontal position errors were suppressed around 1 meter level accuracy under simulated non-GPS availability environment. Under normal GPS environment, the horizontal position errors were under 40㎝ in curve trajectory and 27㎝ in linear trajectory, which are definitely depending on vehicular dynamics.
