When one sensor cannot provide information by sensory deficit or loss, the sensory information can be provided by substituting other sensors for the defected sensor. This sensory substation might be influence on the deteriorated motion perception that consists of multi-sensory information such as visual, vestibular and somatosensory information. In this study, to investigate whether the additional sensation by sensory substitution could be integrated into the motion perception, we examined the effect of substituted postural sway sensation on the directional perception of body movement. Deteriorated motion perception by the reduced plantar sensation was enhanced under sensory substitution condition that provided the body sway information as the plantar vibratory stimulus. These results imply that the additional sensation might be integrated into and improve the motion perception.

Multi-sensory design results from sensory design paradigm and image centricism, which stimulates 5 sensation; visual, auditory, haptic, smell and taste sensation when we experience environment. This is helpful for designing outdoor space considering integrated sensation not only visual and auditory sensation as well as for improving visitor's satisfaction. Therefore, this study mainly intended to analyse the multi-sensory preference and the image influence of outdoor leisure space. For these purpose, this study selected 3 leisure spaces around Seoul city; Gwan-ak mountain(the type oriented natural resource), Insa-dong(the type oriented cultural resource) and Seoul land as theme park(the type oriented facility) and a survey was performed with a total of 204 visitors at the above spaces in winter and summer. The results of this study indicate that visual sensation was evaluated most high at 3 outdoor leisure spaces in both winter and summer. Visitors at Gwan-ak mountain and Seoul land prefer visual and haptic sensation, but visitors at Insa-dong prefer visual and haptic sensation in summer, visual and taste sensation in winter. Above all, this study led the designer to consider diverse sensation to access leisure space, especially haptic sense, which can be an effective design strategy to satisfy visitors.

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.

시각장애인의 시각보조를 위하여 공간 및 방향감각 보조시스템으로 초음파거리계 및 전자나침반을 개발하였다. 초음파거리계는 40 KHz 초음파의 반사를 이용하여 장애물까지 거리 정보를 거리에 비례하는 시간간격의 가청음 자극을 제공하며, 전자나침반은 자기저항브리지를 이용하여 지구자기장을 검출하고 자북 방향 정보를 이마주위의 진동모터를 통하여 촉각자극을 제공하도록 설계하였다. 초음파저리계의 측정범위는 0.065-3.26미터이며 전자나침반의 방향 분해능은 22.5도이다. 그리고 초음파거리계와 전자나침반을 통합한 일체형 시각보조시스템을 구현하였으며 이때 거리정보는 두부에서 진동모터의 위치로 전달하도록 하였다. 본 연구의 목표는 시각장애인의 공간 및 방향감각을 위한 실용적인 보조시스템을 구현하는 것이며, 본 보조시스템을 반복 사용함에 따라 시각장애인의 공간 및 방향감각 기능이 향상될 것으로 추측된다.

디지털 시대의 도래는 상호작용 미디어 아트의 비약적인 발전을 야기시켰다. 특히 관객이 작품과 분리된 대상으로 존재하던 전통 미술의 형식에서, 관객이 직접 작품 내에 접속하여 상호작용하고, 그 세계 내 일부, 주체로 활동하게 됨은 타 미술장르와 구별되는 그것만의 독자적인 특성이다. 본 연구의 목적은 인터랙티브 미디어 아트의 상호작용 과정들을 분류화 하여, 메를로 퐁티의 몸 현상학 이론들과 비교하고 그 의미를 고찰함에 있다. 메를로 퐁티의 몸 현상학은 대상/세계, 의식/정신, 주/객 등 이항대립적 사유가 만연하던 서구 지성사를 몸을 통한 통합적 인식을 주장하며 그 한계를 뛰어 넘고자 하였다. 이와 같은 세계와 주체의 새 시각을 견지한 메를로 퐁티의 몸 현상학 이론을 미디어 아트의 상호소통 과정의 세부 요인들과 비교하려는 것이다. 이를 위해, 미디어 아트의 상호작용 과정을 <작품 구성, 감상의 주요 요인인 관객의 신체>, <작품 감상방법의 현존적 체득>, <정해진 프로그램 내의 유영>, <통합되는 감각>, <가상세계 내에서 활동>으로 세분화하고, 이를 메를로 퐁티의 몸 현상학 이론 중 <몸틀>, <습관의 획득>, <몸의 구조화>, <지평의 종합>, <세계-에로-존재> 개념들과 비교하여 상호 유사점 및 의미를 탐색하였다. 그 결과 미디어 아트의 상호작용 과정에서 도출되는 신체성, 공감각성, 다중감각, 공간성 등은, 타 미술장르 및 미니멀리즘 미술양식보다 더욱 메를로 퐁티의 몸 현상학 이론들과 일맥상통함을 명료하고 세세하게 밝힐 수 있었고, 이를 통해 현대 상호작용 미디어 아트의 연구에 대한 새로운 방향을 제시할 수 있었다.

There is no doubt that BSC(Balanced Scorecard), ABC(Activity-Based Costing System), EVA(Economic Value Added System) draw sensation in the world as the tools of Performance Evaluation System and Quality Control. They are useful tools that can help succeed in the dynamic and competitive business environment. These three tools are discussed respectably. However, it also brings doubt whether it is possible to integrate the three tools made in the similar time and which way is appropriate among the three tools according to the type and the circumstance of business. In fact, these tools are not the opposing relations but the complementary relations. Consequently, this paper explains the relations of the three methods and suggests the process of the integrated models. Besides, it provides an idea about when Performance Evaluation System and Quality Control are needed for companies under different aspects considering the circumstance used the respective methods individually.

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.

Lines of non-extension (LoNEs) on torso surface during arm abduction were investigated to provide appropriate location for inserting less-extensible yarns which can be used as seams for design and or clothing pressure variation. As experimental methods, reference points about 3 cm apart were marked on the skin and scanned at 30, $90^{\circ}$ and $135^{\circ}$ arm abduction. Skin deformation was measured by connecting reference points in horizontal, vertical and various angles of diagonal directions. Observation of skin deformation was made within the separated sections of the torso as well as integrated ones to cover the various occasions of design application. LoNEs of front and back torso were provided as mapping lines. Actual compression wear of three types was constructed with different pattern reduction rate at each separated section using LoNEs as boundary cutting lines. Clothing pressure and subjective evaluations of those three compression wear were evaluated by six subjects. LoNEs found in this study were useful as seam lines to differentiate clothing pressure at each part of the body, providing positive wear sensation. It is also expected that LoNEs can be paths for less strechable conductive yarns of IT-integrated upper garments.

In this paper, various structures of the healthcare smart clothing for real-time measurement of vital sign were suggested. The wearing efficiency was evaluated to find out the best ergonomic clothing in the suggested design. The supplementary effects of the clothing components (princess line, double fabric, cushion) on the stable and tight positioning of sensors to the body were evaluated with wear test. Five experimental clothing for male subject were made with closely-fitted shape and they included two representative structure: one was the integrated type of inner and outer garments and the other was the separated type with two garments. Eight subjects in their twenties were participated in the wear test to evaluate the wearing efficiency of experimental clothing. As results, the clothing structure of the separated garments with the inner and the outer shells were evaluated as more efficient and comfortable. However, the effects of clothing components on the light positioning of the sensors to the body surface were not differentiated each other in the subjective evaluation.
