  • Human uses sight, tactile sense to evaluate Total Hand Value(FUUAI) of textile fabrics. Tactile sense is important factor which decided the Total Hand Value of a textile fabric. When human feels the FUUAI, physical and physiological phenomena are occurred in finger. We first found out physical variable that is happened in fingertip when human is feeling the FUUAI. Such physical variable means characteristic of action tactual motion of finger such as moving range, tactile time, moved distance, speed of finger and applied force by finger. We study the relationship between action tactual motion and the ability in which the human distinguishes the textile fabric. As a result, we could know the characteristics of the tactual motion of fingertip to get high distinguishable ability. The characteristics were different in men and women respectively. In the case of man, touched time and moving range influenced to distinguish, and moving range, and the moving speed of finger influenced, in woman's case.

  • The extraction and recognition of human motion characteristics need to combine biometrics to determine and judge human behavior in the movement and distinguish individual identities. The so-called biometric technology, the specific operation is the use of the body's inherent biological characteristics of individual identity authentication, the most noteworthy feature is the invariance and uniqueness. In the past, the behavior recognition technology based on the single characteristic was too restrictive, in this paper, we proposed a mixed feature which combined global silhouette feature and local optical flow feature, and this combined representation was used for human action recognition. And we will use the KTH database to train and test the recognition system. Experiments have been very desirable results.

  • Objective: The aim of this study is to investigate visual feedback effects and human performance in the foot mouse control. Background: Generally, computer mouse tasks are controlled by visual feedback. In order to understand the characteristics of a foot mouse control, it is important to investigate the patterns of visual feedback involved in foot-mouse control tasks. Human performance of foot mouse control is also an important factor to understand the foot mouse control. Method: Three types of mouse control were determined to investigate visual feedback effects and human performance in the foot mouse control. Visual feedback effects in the foot mouse control were compared with those of a typical hand mouse. The cursor movement speed and mental workload were measured in the three types of tasks and two types of mouses. Results: Mouse control tasks with an element of homing-in to the target were more quickly performed by the hand mouse than the foot mouse. Mental workload was also higher in the foot mouse than the hand mouse. However, in the steering movement, human performance of the foot mouse control was not lower than that of the hand mouse control. Visual feedback in the foot mouse control was less required than in the hand mouse control. Conclusion: The foot mouse was not efficient in the most mouse control tasks, compared to the hand mouse. However, the foot mouse was efficient in the steering movement, moving a cursor within a path with lateral constraints. Application: The results of this study might help to develop the foot mouse.

  • To understand the developmental process of the gait pattern from infancy to the adult, a gait analysis for a 14 months female infant has been performed for ten weeks. The gait parameters has been measured every other week since the week when she was able to walk without aid. The infant gait data at the tenth week of the test shows a similar pattern to the adult gait in many aspects including initial knee flexion, initial ankle dorsiflexion, the push-off pattern, etc. There is not a significant change in the hip flexion angle from week to week from the two weeks after the test started. To check the individuality in the collected data, more infant subjects are being tested presently.

  • The purpose of this study is to measure perceived joint discomfort in the seated and standing position, and to provide a ranking system of joint discomfort measured in this study. Seven male subjects with no history of musculo-skeletal disorders participated in the experiment. Their physical characteristics were: age -$27.6 {\pm}1.8$ years, stature -$171.0 {\pm}5.5cm$, and body weight -$66.4{\pm}9.3kg$. The results showed that perceived joint discomfort was different depending on the human body joints involved in motion and their movement directions, which imply that the human body motions should be classified intoseveral distinct classes that need to be assigned different weights of postural stress. In the seated postion, the hip movement was the most stressful, the back was the second, and the shoulder was the third. Similarly, in standing postures, the hip was given the highest ranking, followed by the back, and the wrist.

  • From ancient times to today the formation of centrality in architecture has taken very important role as an organizing device. However after 19th century modem architecture focused on the universal aspect and homogeneity of space, and developed its own vocabulary through de-centralization. Since 1960's the reflections on de-humanized space of modem space have been evloved. As those movement has been understood seriously, the centrality can be changed to phenomenological one. And The phenomenological centrality maintains organic balance with its surroundings not trying to form a hierarchic system. So it shows human-oriented tendency and facilitates experiential movements of human body. And it also gives a sense of being. The phenomenological centrality is comprised of center, boundary, and two types of axis. The characteristics of phenomenological centrality can be analyzed as practical and meaningful center, visible boundary, experiential movement, and unexpectable encounters with spaces and nature.

  • 선(lines)은 인류 역사에서 가장 오래된 시각적 요소이자 인간의 삶과 밀접하게 연관됐으며, 동굴벽화나 바위에 선으로 그려진 그림 및 기호는 인간의 생존을 위한 대체 이미지로 존재해 왔다. 미술에서 선은 단시간 내에 대상의 핵심을 드러내며, 미술치료에서는 내담자의 심리적 상태를 진단하고 치료적으로 개입할 수 있는 매개체가 된다. 그러나 선 그리기, 즉 선화(line drawing)는 진단뿐 아니라 과정상에서 치료적 중요성을 지님에도 불구하고 그 효용성과 치료적 특성을 고찰한 연구는 활발히 이루어지지 못했다. 따라서 본 연구에서는 미술치료에서 선화와 연관된 국내외 문헌을 이론 삼각검증, 질적 내용분석, 공통부분 찾아내기를 통해 우선 도출한다. 그 결과 선화의 핵심적인 치료적 요소인 운동성을 뇌 구조와 연결하여 살펴본다. 이를 통해 선화의 운동성이 신체, 뇌, 마음에 미치는 치료적 메커니즘을 고찰하고 미술치료 안에서 어떻게 치료적으로 활용 가능한가를 검토 및 제안하는 데 학문적 의의를 둔다.

  • Ride comfort, one of the most important performances of a car, is affected by vibration, noise, dynamic movement, and ergonomic factors. Among these factors, ride comfort vibration is heavily affected by the seat system, tire, suspension, and body structure. In this study, vibration characteristics of seat, tire, suspension, and body structure are analyzed. The vibration transfer function from the road input to the human body is also investigated.

  • This study examined the characteristics of generative design methodology, and it selected and analyzed 11 sites that provide design development services using generative methodology, INPUT data were classified into design form factor based on the choices of each and the variable form associated with each participant's movement. In designing the algorithms, designers set the meth- od and range of participation according to the characteristics of the design, and linked them with design components. This provided the study with a discriminative design process. This resulted in a type with morphological characteristics and a type that emphasized epidermal formability. The generative design methodology has value as an alternative process in the field of fashion where the utilization of digital technology is becoming universal based on contingency and variability. The results of this study can be used as basic data for the study of personalized design through the extension of methodology of digital-based fashion design and generative methodology.

  • 인체의 동작 센싱 방법에 대한 연구가 다양하게 진행되어 왔으나, 기존의 동작 센싱 방식에는 많은 한계점들이 있다. 기존의 동작 센싱 방식의 한계점을 보완하기 위한 일환의 노력으로, 이 논문에서는 비구속적인 동작 센싱이 가능한 광섬유 기반 의류 소매형 동작센서를 탐색적으로 연구하는데 목표를 두었다. 이 논문에서는 광섬유 기반의 의류 소매형 동작 센서를 고안하고, 이를 통하여 일상생활 중에 다양한 동작을 센싱하는 것이 가능한가에 대하여 탐색적 연구를 수행하였다. 또한 본 연구의 범위는 광섬유 기반 동작센서의 가능성 여부와 주요 요건을 탐색하는 것이며, 소매 패턴과 봉제 방식의 특성, 착용자의 체형 특성이 미친 영향은 연구 범위에서 제외되었다. 이러한 방식으로 의복에 적용 가능하도록 고안된 광섬유 기반 의류 소매형 동작센서는, 기존의 동작 센싱 시스템에 비하여 더욱 미세한 인체 동작 측정이 가능하며 시간 공간의 제약 없이 저 비용으로 인체 동작 측정이 가능하다는 장점을 갖는다.
