We have long kept our Cartesian tradition in which Mind privileges over Body; the invention of printing technology has accelerated the tradition in which the intelligence and legibility of media were considered as a higher human value. However, the development of media and technology are supporting the multisensory mechanisms of the body as it was in preliterate era when we communicated with our whole bodily experiences. The development and spread of mass-media and new technologies have broaden the boundary of human sensory that are largely dominated by visual information and expanded it to auditory, olfactory and even gustatory sensation. Since 1960's, some philosophers and artists have recognized the human body as a subjective matter, starting the movement in which the body plays a role as an essential factor in study of human perception and cognition, aesthetics in art, and sociology, and the changed perspectives are practiced vigorously in the field of new media art; the theory of Maurice Merleau-Ponty who clarified the body as a general means for the body's possession of world, so that recognize the importance of cognition of one's body and approved the embodiment could be applied and practiced here. Therefore, we discuss how Merleau-Ponty's philosophical theory can be practiced and how McLuhan's perspective could be applied on the notion of body's extension in media by analysing some new media art cases.

The field of body sensor networks has attracted interest of many researchers due to its potential to revolutionize medicine. These sensors are usually implanted inside the human body and communicate among themselves. In the process of receiving, processing, or transmitting data, these devices produce heat. This heat damages the tissues surrounding the devices in the case of prolonged exposure. In this paper, to reduce this damages, we have improved and evaluated two protocols-the least temperature routing protocol and adaptive least temperature routing protocol-by implementing clustering as well as a leadership rotation algorithm. We used Castalia to simulate a basic body area network cluster composed of 6 nodes. A throughput application was used to simulate all the nodes sending data to one sink node. Simulations results shows that improved communication protocol with leadership rotation algorithm significantly reduce the energy consumption as compared to a scheme without leadership rotation algorithm.

In this paper, we propose a technique for tracking the classification and location of each user through body proportion analysis of the normalized skeletons of multiple users obtained using RGB-D cameras. To this end, each user's 3D skeleton is extracted from the 3D point cloud and body proportion information is stored. After that, the stored body proportion information is compared with the body proportion data output from the entire frame to propose a user classification and location tracking algorithm in the entire image.

This study aims at strengthening the national competitiveness of Korea's clothing industry as it provides substantial information on the human body proportion and proportional dimension standards for Chinese women and improves the fitness of clothing, considering human proportion in the production of clothing products for export to China. This study selected by simple random sampling Chinese women in Beijing and Shanghai, China, whose age is between 19-50 from June 23 to August 7, 2004. The stature of the average Chinese woman belonging to the High Frequency group is 7.09 times as long as the length of the head. We developed the body proportional dimension standards with the same proportion with High-Frequence group. The basic size of proportional dimension standards for Chinese women has the stature of 159cm, (chest circumference)/2 of 42.8cm.

As recent virtual reality technologies provide a more natural three-dimensional interactive environment, users naturally learn to explore space and interact with synthetic objects. The virtual reality researcher develops a technique that realizes realistic sensory feedback to get appropriate feedback to sense input behavior. Although much recent virtual reality research works extensively consider the human factor, it is not easy to adapt to all new virtual environment contents. Among many human factors, distance perception has been treated as very important in virtual environment interaction accuracy. We study the experiential virtual environment with the feature of the virtual object connected with the real object. We divide the three-dimensional interaction, in which distance perception and behavior have a significant influence, into two types (whole-body movement and direct manipulation) and analyze the real and virtual visual distance perception heterogeneity phenomenon. Also, we propose a statistical correction method that can reduce a near-body movement and manipulation error when changing the interaction location and report the experiment results proving its effectiveness.

Human motion tracking algorithm is receiving attention from many research areas, such as human computer interaction, video conference, surveillance analysis, and game or entertainment applications. Over the last decade, various tracking technologies for each application have been demonstrated and refined among them such of real time computer vision and image processing, advanced man-machine interface, and so on. In this paper, we introduce cost-effective and real-time human motion tracking algorithms based on depth image 3D point matching with a given superellipsoid body representation. The body representative model is made by using parametric volume modeling method based on superellipsoid and consists of 18 articulated joints. For more accurate estimation, we exploit initial inverse kinematic solution with classified body parts' information, and then, the initial pose is modified to more accurate pose by using 3D point matching algorithm.

In recent years, it is important to visualize an accurate human body model for the low-end system in the medical imaging field where augmented reality technology and virtual reality technology are used. Decreasing the geometry of a model causes a difference from the original shape and considers the difference as an error. So, the error should be minimized while reducing geometry. In this study, the organ areas of a human body in the tomographic images such as CT or MRI is segmented and 3D geometric model is generated, thereby implementing the reconstruction method of multiple resolution level-of-detail model. In the experiment, a virtual reality platform was constructed to verify the shape of the reconstructed model, targeting the spine area. The 3D human body model and patient information can be verified using the virtual reality platform.

The size and shape of the human body has been an important factor not only in anthropology but in integration of designs aimed for daily use. Although the three-dimensional measurements have been proposed and obtained introducing new methods, there still remains many problems concerning how to analyze and evaluate the results. In this study, we have got the internal and external orientation factors, image coordinates from the ac-quired photographs, have calaulated the object coordinates through Bundle Adjustment, have matched multi-images. have drawn the object in the computer, and smoothly handled the surface of the body model using the Au-to-CAD system or graphic processing utility then we could generate the digital model of human body. The. results show that once digital modeling of the body is generated. the information which a designer needs can be acquired and the adequate calculations for many application fields can be done easily and many geometrical properties could be extracted. Therefore we propose the possibility of indirect human body measurement through digital model generation.
