The purpose of this research was to analyze how the evaluation method affects the subjective hand evaluation of fabrics and to suggest the efficient evaluation method. Three methods such as the sense of sight ＆ touch, the sense of touch, and the sense of sight were respectively used when judges estimated the hand of fabrics using questionnaire. The result obtained by the method of touch was same as that by the method of sight ＆ touch. The time required for the evaluation by these two methods was statistically same. Consequently, the method of touch has no attraction compared to that of touch ＆ sight. In case of using the method of sight, 8 properties among 10 showed the same results as in the method of sight ＆ touch. The properties of [moogupda/kabyupda] and [shinchuksung-e-itda/ shinchuksung-e-upda] evaluated with the sense of sight were different from the results obtained by the other methods. These properties seem to be difficult to evaluate only by seeing the fabric on the table. For the precise evaluation, it is necessary to show dynamic movement of the fabric. The time required for the evaluation by the sense of sight was shorter than that by the other two methods.

재생되는 동영상에서 정지, 재생, 캡쳐, 확대, 축소 등의 다양한 이벤트 제공은 스마트폰과 같은 작은 크기의 모니터에서 가능하다. 그러나, 모니터의 크기가 커지게 되면, 터치 인식에 대한 비용이 증가하게 되어, 터치를 통한 이벤트 제공은 사실상 불가능하다. 본 논문에서는 저렴하게 깊이 정보로 터치를 인식하고, 단일 및 다중 터치로 토글, 핀치-인/아웃 등의 다양한 이벤트를 부여하는 영상 이벤트 제어시스템을 제안한다. 깊이 카메라로부터 얻어진 깊이 정보로 터치된 위치와 터치 경로를 찾고, 터치 제스처 종류를 파악한다. 이러한 터치 인터페이스 알고리즘은 소형 싱글보드 시스템에서 구현하고, UART 통신을 통해 제스처 정보를 전송함으로써 영상 이벤트를 제어할 수 있다. 모의실험을 바탕으로 대형 스크린에서 제안한 깊이 터치 방법으로 다양한 영상 이벤트를 제어할 수 있음을 보인다.

중대형 터치스크린의 일반적인 방법으로 적외선을 이용하고 있지만 이 방법은 터치인식장치의 설치가 어렵고, 응용의 범위가 제한적이며, 멀티포인트 방식에서 좌표오류가 발생하는 문제점을 가진다. 가시광선을 이용하는 일반 카메라를 이용한 터치 스크린의 경우 접촉이 일어난 위치 이외에서 접촉 물체의 색상정보를 이용할 수 있기 때문에 적외선을 사용하는 터치스크린보다 활용성이 뛰어나다. 또한 적외선 터치스크린에 비하여 설치가 간편한 장점을 가진다. 그러나 주변의 색상 및 조도에 따라서 인식 성능이 달라지고, 스크린의 반사광도 인식되는 문제점을 안고 있어 지금까지 큰 호응을 얻지 못하고 있다. 본 논문에서는 일반 카메라를 사용하는 터치스크린의 구조, 접촉 물체의 인식 및 싱글 포인트 및 멀티 포인트의 좌표 연산과정에 대하여 연구한다. 이 방법은 싱글 포인트의 터치스크린에서 적외선 카메라방식과 동일한 인식성능을 보였다. 멀티 포인트 터치스크린은 접촉 물체의 거리정보를 이용하여 기존의 터치스크린이 가지고 있는 고스트 포인트(Ghost point)를 해결하였으나, 싱글 포인트 터치스크린에 비하여 인식성능이 감소하였다. 실험 결과에 따르면 싱글 포인트 터치스크린의 수행속도를 개선할 경우 적외선 카메라방식을 대체 가능함을 알 수 있다.

With the new millennium setting in, our society is plowing its way through more drastically changing currents than ever. Nowadays, many people believe that high tech such as the Internet, digital civilization, the IT revolution, bio-industry, and the genome project, that has brought humans material prosperity, is the right change in direction. However, the more we adopt high tech into our lives, the more we desire high touch in order to achieve a balance. In other words, we need something to act as a ballast to stabilize our minds. As such, the more high tech develops, the more individuals miss and search for tools that appeal to their emotions. Because of this, although high touch is an opposite concept to high tech, it coexists with high tech, and it is defined as "human contact of high sensitivity that stimulates the emotion of humans". High Touch, a term which originated from "High Tech, High Touch", a book written by American futurist John Naisbitt, refers to human contact that makes human life richer, forminga deep impression on individuals and providing comfort. As such, high touch, which is gaining significant attention in modern society, is a phenomenon occurring throughout politics, society, culture, art, and religion, together with high tech. Through high touch, modern people must realize how to understand and accept a modern society that is dominated by the age of technology and in which direction they should head. Under this background, this study has the following objectives: to interpret the concept of high touch in the age of high tech in association with formative art and fashion, and through various media examine the desire for expression that may stimulate emotion in modern people, which is required by the high tech-prevalent modern society. It further analyzes how high touch is reflected in modern fashion and presents the direction future fashion should head in.

The present study examined the effectiveness and communications functions of mothers' touch on the responses of their 6-month-old infants using the Still-Face (SF) situation. Participants were 67 infant-mother dyads from Seoul and Gyeonggi province. Positive and negative responses of infants were measured by SF interactions and by three different touch conditions. Touch types were measured by a coding scheme based on Suchung Kim and Keumjoo Kwak (2003; 2(04). Results showed that mothers' touch affected baby's responses by increasing positive responses and decreasing negative responses. The positive and negative responses of infants differed by the three different touch conditions, indicating that mothers use different touch types according to touch conditions; these variations in touch function as an important channel of communications.

This paper presents a compact and low-power on-chip touch sensor and readout circuit using shunt proximity touch sensor and its design scheme. In the proposed touch sensor readout circuit, the touch panel condition depending on the proximity of the finger is directly converted into the corresponding voltage level without additional signal conditioning procedures. Furthermore, the additional circuitry including the comparator and the flip-flop does not consume any static current, which leads to a low-power design scheme. A new prototype touch sensor readout integrated circuit was fabricated using complementally metal oxide silicon (CMOS) $0.18{\mu}m$ technology with core area of $0.032mm^2$ and total current of $125{\mu}A$. Our measurement result shows that an actual 10.4 inches capacitive type touch screen panel (TSP) can detect the finger size from 0 to 1.52 mm, sharply.

This study has been conducted on touch screen interface design for mobile devices. It was intended to measure user’s satisfaction on one-handed thumb input mobile devices. Recent studies proposed the optimal touch button size, but it is inappropriate for mobile devices. Therefore, this study was focused on four touch key factors-width, height, the horizontal and vertical distance between touch keys-as independent variables. The ANOVA results showed that the user satisfaction of four touch key factors was significantly affected by the thumb input. It also apparent that the interactions between four factors were significant. As a result, the horizontal and vertical distance as well as the width and height affected the satisfaction of users. In addition, this study suggested satisfaction models which represent the top 30%, 50%, 70% of user satisfaction measurement. The results of this study could be used to design touch keys that are able to enhance the usability on touch screen based mobile devices.

The purpose of this study is to examine the compensatory role of instrumental (e.g., product information) and aesthetic (e.g., website background) online cues presented within apparel websites where touch is unavailable. The moderating role of two need for touch (NFT) dimensions (i.e., autotelic and instrumental NFT) between online cues and consumer responses was also investigated. Results demonstrate that personal differences in autotelic and instrumental NFT moderate the relationship between online cues and affective responses. It was found that consumers high in autotelic NFT (i.e., who need to touch for fun) seek more instrumental cues to compensate for lack of touch when shopping apparel products online. Surprisingly, consumers high in instrumental NFT (i.e., who need to touch for product evaluation) use aesthetic as well as instrumental cues to supplement the absence of touch. In contrast, for the low NFT groups, only aesthetic online cues showed significant effects on consumer arousal. Further analysis shows that instrumental NFT is negatively related to purchase intention while autotelic NFT has a positive effect on purchase intention. This implies that need for hedonic-oriented touch is no longer a barrier for online apparel shopping. However, the instrumental NFT seems a significant obstacle for the adoption of online apparel purchasing.

Current touch pen requires the special equipments to detect a touch and its price increases in proportion to the screen size. In this paper, we propose a method for detecting a touch and implementing a pen using the depth information. The proposed method obtains a background depth image using a depth camera and extracts an object by comparing a captured depth image with the background depth image. Also, we determine a touch if the depth value of the object is the same as the background and then provide the pen event. Using this method, we can implement a cheaper and more convenient touch pen.

We can implement the virtual touch recognition system by mounting the virtual touch algorithm into an embedded device connected to a depth camera. Since the computing performance is limited in embedded system, the real-time processing of recognizing the virtual touch is difficult when the resolution of the depth image is large. In order to resolve the problem, this paper improves the algorithms of binarization and labeling that occupy a lot of time in all processing of virtual touch recognition. It processes the binarization and labeling in only necessary regions rather than all of the picture. By appling the proposed algorithm, the system can recognize the virtual touch in real-time as about 31ms per a frame in the depth image that has 640×480 resolution.
