3D scan images have been successfully applied in ergonomic product design. Features of human body parts (e.g., landmarks, measurements, curvatures, surfaces, volumes) extracted from 3D body scan images can be used to analyze variations of the size and shape of human bodies. The information of size and shape variations can be applied in product design to support technical ideas regarding accommodation, tolerance, and adjustability. This study is aimed to briefly introduce a few analysis methods of body shape variation using 3D facial scan images of Dutch children in order to acquire useful features for the design of a children’s facial mask.

Purpose – The purpose of this paper is to present results of shape analysis of female torso shape using the discrete cosine transform (DCT) from a three-dimensional (3D) whole body scan database. Design/methodology/approach – Torso shape is a central part of body shape and difficult to describe by linear measurements. In order to analyze body shape variation within a population the authors employed a DCT-based shape description method to compresses a dense 3D body scan surface into a small vector that preserves shape and removes size. The DCT-based shape descriptors of torso surfaces are further fed to principal component analysis (PCA) that decompose shape variation into constituent shape components. A visualization program was developed to observe principal components of torso shape and interpret their meanings. Findings – Extreme shapes of the first ten principal components summarize major shape variations and identify shapes that are difficult to capture with traditional anthropometric measurements. PCA results also help to find and retrieve similar shapes from a population-level database. Originality/value – Using the DCT for PCA of torso shape is a unique and original approach. It provides a basis for the description and classification of torso shape in 3D and the results from the shape analysis are potentially useful for designers of clothing and personal protective equipment.

Research Institute of Human Engineering for Quality Life (HQL) is planning to update the current human body measurement database by collecting new body measurement data, as well as it carries out the following development of measurement technology from 1999 to 2001. I. Development of New 3-D Body Surface Measurement System (1999 ∼ 2001) a. Generation of the super accurate data and reduction of the measuring time b. Measurement of the invisible human body parts c. Extraction of anatomical landmarks II. Development of New Data Format for 3-D Human Body Shape (1999) The human body shape generated from image data has difficulty in comparing data and comprehending distribution. This project aims at conducting the research and development to make the scan result easier to analyze and utilize.

Scan Data

Whole human body scanners are 3D imaging devices which are capable of capturing a computerized format of whole body shape, thus permitting automatic extraction of the different body measurements. This requires the segmentation of scan data into subsets corresponding to the functional human body parts. Such a task is quite challenging due to the articulated and the deformable aspects of the human body shape. The attempts made so far suffer from various limitations, such as being restricted to standard specific posture and vulnerability to scan data corruption. This paper proposes a general framework that aims towards overcoming these challenges. One of the salient features of this framework is that it can cope with moderate posture variations around the standard posture, in addition of being quite robust against noise, holes and irregular sampling. Experimental results performed on real and synthetic data confirmed the validity, effectiveness and robustness of our framework.

Statistical Shape

Measurements of human body size and shape are an important source of information for a range of scientific fields and applications; however, practitioners still rely on traditional tools and methods which limit the kinds of measurements that can be taken. Recent literature has suggested that 3D imaging technology is a more sophisticated tool that could enable the comprehensive characterisation of human body shape. The aim of this programme of doctoral study was to determine whether shape anthropometrics can complement existing techniques in the assessment of human morphology. A novel analytical procedure was developed using geometric morphometrics and statistical shape analysis methods to extract numeric parameters from 3D imaging data, which describe scale-invariant characteristics of human torso shape. Though errors in anatomical landmark identification and participant scanning posture can affect the acquisition of shape anthropometrics, the developed methods were found to have high test-retest reliability, suitable for use within subsequent investigations. A series of investigations were conducted to determine whether shape measures provide additional information which is not captured by existing anthropometric techniques. The findings of these investigations suggest that body shape measures show a complex dependence on body size. Though certain shape features demonstrate a degree of allometric scaling and change with increases in body size, there are significant proportions of shape variation which cannot be explained by existing anthropometrics. These non-allometric variations in body shape have been shown to improve the estimation of subcutaneous abdominal adiposity in a small cohort of participants, and have demonstrated the potential for misclassification of individuals using existing indices, such as BMI and WHR. This programme of research provides a more detailed understanding of human morphological variation, which could inform the development of improved tools for characterising how body shape relates to its underlying mass distribution.

The Law

This chapter surveys the current legal position concerning property in bodies and bodily materials. Of especial relevance in the current age of advanced genetic and other bio technologies, it looks beyond property in bodies and their materials ‘as such’ to consider also (a) the availability of rights of personal and intellectual property in objects incorporating or derived from them, and (b) the reliance on quasi-property rights of possession and consent to regulate the storage and use of corpses and detached bodily materials, including so-called ‘bio-specimens’. Reasoning from first principles, it highlights the practical and conceptual, as well as the political and philosophical, difficulties in this area, along with certain differences in the regulatory approach of European and US authorities. By way of conclusion, it proposes the law of authors’ and inventors’ rights as simultaneously offering a cautionary tale to those who would extend the reach of property even further than it extends currently and ideas for exploiting the malleability of the ‘property’ concept to manage the risks of extending it.
