This paper presents a new miniature haptic display to convey ample haptic information to a user of a handheld interface. There are buttons on interfaces or general electronic devices, but existing buttons provide haptic feedback of only one passive pattern to a user. Because humans perceive tactile and kinesthetic information simultaneously when they handle objects the proposed actuator provides both sensations at once. It is able to generate various levels of kinesthetic sensations when pressing a button under diverse situations. Also, vibrotactile feedback can be delivered for exciting haptic effects with numerous patterns. Its performance was evaluated in accordance with the resistive force by changing the intensity of the input current. Experiments show that the proposed actuator has the ability to provide numerous haptic sensations for more realistic and complex haptic experiences.

The purpose of this study was to analyze the effects of consumers' fashion design evaluation factors on design value and brand loyalty. After confirming a research hypothesis, 247 people were selected as subjects for empirical analysis, and the results of the study are as follows. As a result of the analysis of 'the influence of consumer's fashion design evaluation factors on design value', the fashion design evaluation factors of 'convenience', 'social activity usefulness' and 'fashion ability' had an effect on the emotional design value. 'Convenience', 'functional usefulness', 'social activity usefulness', 'fashionableness' and 'aesthetic' factors affected the rational design value. 'Convenience', 'fashionableness', 'aesthetic' and 'psychological self-conformity' had a positive (+) effect on kinesthetic design values. As a result of the analysis of 'Influence of consumer's fashion design value on brand loyalty', 'emotional design value', 'rational design value' and 'kinesthetic design value' affect attitude brand loyalty, and 'emotional design value' and 'kinesthetic design value' affect brand loyalty. It was found that 'kinesthetic design value' has an effect on behavioral brand loyalty. As a result of the analysis of 'the effect of consumer attitude brand loyalty on behavioral brand loyalty', it was analyzed that attitude brand loyalty had a statistically significant positive (+) effect on behavioral brand loyalty.

최근 디지털 네이티브 학습자를 위한 교수방법으로 게임활용학습에 대한 관심이 증가하고 있다. 이에 본 연구에서는 초등학교 역사수업에 맞추어 개발된 동작인식 게임을 활용하여 수업을 실시한 후 신체운동지능, 언어지능, 몰입, 학습성과(학업성취도, 지속의향) 간 경로분석을 실시하였다. 그 결과 신체운동지능은 몰입에 직접적인 영향을 학습성과에는 간접적인 영향을 미쳤고, 언어지능은 몰입에 직접적인 영향, 그리고 학습성과에의 간접적인 영향을 미치지 않는 것으로 분석되었다. 이 결과를 통해, 동작인식 게임활용학습은 신체운동 역량이 높은 학습자들의 학습동기 및 성과 향상을 지원할 수 있음을 기대하게 한다.

The primary purpose of this study was to investigate the influence of Cognitive Factors (CF) on the Creative Abilities (CAs) in design. We set up a model of Cognitive Design Process (CDP), which consists of four domains: Concepts, Experience, Five Senses (FS), and Thinking Modes (TM). Here, experience is first perceived by the five senses, and then recognized by intelligence. We regard design as a transforming process from concept to experience. For this study, two major Sensory Modalities (Visual and Kinesthetic), four Thinking Modes (Brain Dominance Profile), and four Creative Abilities (Fluency, Flexibility, Originality, and Elaboration) were reviewed. We hypothesized that idea generation is influenced by different Sensory Modalities (Visual Sense vs. Kinesthetic Sense) and Thinking Modes, and that these have a close relationship with the attributes of CAs. Firstly, we have examined the cognitive thinking model in design. Then, we adapted the Test of Creative Abilities of Design Thinking (TCADT) for measuring CAs. We surveyed the CAs under CF in particular. Finally, we have investigated the influences of the different Sensory Modalities (Visual Sense vs. Kinesthetic Sense) on CAs. It was found that a close relationship between Brain Dominance and CAs, and Sensory Modalities (SM) have different influence on these creative abilities. As a result, a tool for the Test of CAs and a framework for creative idea generation with the effective CF will be presented. These provide the basis for a new approach to creative idea generation in Experience Design.

In this paper, we suggest an integrated tactile display system that provides kinesthetic force, pressure distribution, vibration and slip/stretch. The system consists of two parts: a 2 DOF force feedback device for kinesthetic display and a tactile feedback device for displaying the normal stimulation to the skin and the skin slip/stretch. Psychophysical experiments measure the effects of fingerpad selection, the direction of finger movements and the texture width on tactile sensitivity. We also investigate the characteristics of lateral finger movement while subjects perceive different textures. From the experimental results, the principal parameters for designing a tactile display are suggested. A tactile display device, using eight piezoelectric bimorphs and a linear actuator, Is implemented and attached to a 2 DOF translational force feedback device to simultaneously simulate the texture and stiffness of the object. As a result, we find out that the capability of the suggested device is sufficient to display physical quantities to display the texture.

The basic technology of virtual reality can be described as the cognition of the condition change in virtual world by stimulating the visual, auditory, kinesthetic and tactile sensation. Among these, the kinesthetic and tactile sensation is one of the most important things to recognize the interaction. In this paper, it is addressed the haptic device which help the human feel the sense of the operator, and is designed in modular type to expand for five fingers later. the haptic device is driven by tendon and ultrasonic motors located in the wrist part. Each joint is actuated by coupled tendons and adopts more actrator by one than the number of the joints, called 'N+1 type'. The haptic device adopts metamorphic 4-bar linkage structure and the length of linkages, shape and the location of joint displacement sensor are optimized through the analysis.

In this paper, a new control scheme for master-slave control of telerobot is proposed. The porposed method can be classified into unilater master-slave control methods in the aspect of the data flow. But the master arm in the proposed control scheme can deliver operator the similar kinesthetic sense as other bilateral force reflecting master arms do. The principle concept is that the sensed operator's force/torque is used as the reference input for a damping controller type of telerobot controller which track the operators efforts. Master arm and master controller can be implemented in a simple form, and it needs not be driven by actuators, but force sensing capability.

Tactile sensation is essential for many manipulation and exploration tasks not only in a real environment but also in a virtual environment. In this paper, we discuss a conceptual design of an integrated tactile display system. The system comprises two parts: a 2 DOF force feedback device for kinesthetic display and a tactile feedback device for displaying the normal stimulation to skin and the skin slip/stretch. Psychophysical experiments measure the effects of fingerpad selection, the direction of finger movements and the texture width on tactile sensitivity. We also investigate characteristics of lateral finger movement while subjects perceive different textures. From the experimental results, the principal parameters for designing a tactile display are suggested. A tactile display device is implemented using eight piezoelectric bimorphs and a linear actuator, and is attached to a 2 DOF translational force feedback device to simultaneously simulate texture and stiffness of the object.
