“…This traditional measurement approach to understanding how and where dimension change is occurring on the body is inadequate. Recent research comparing the body in different positions using 3D technology has improved our understanding of how linear measurements change, but the analysis continues to rely on traditional 1D anthropometric methods [1,2,7,8]. When using traditional methods to measure circumferences, despite significant visual shape change of the body, the overall circumference change between positions has been shown to be minimal [1,9].…”

“…Traditional landmark locations from the waist to the knee include: waist at front, back, left and right, the tenth rib, iliospinale anterius, max prominence, crotch level, maximum thigh, mid thigh and suprapatellar [10]. Many landmark methods have been developed to capture the body in a standard A-frame and dynamic postures, including the use 3D markers [1], stickers and markers [2,7], stamps [11], and light projection [12]. Incremental landmark spacing [2,8] and body crease lines [7] have also been used to track movement of the body.…”

“…Many anthropometric studies have used 3D scanning technology to capture the human form in a standard A-frame position and seated position [1,2]. However, the in-depth analysis of the full waisthip-thigh region of the body in dynamic poses, such as a seated position, has been limited due to poor scan resolution, lack of color, minimal landmarking, and obstructed views in critical areas such as the hip, inner thigh, and crotch [3,4,5,6].…”

The purpose of this research was to explore new methods of 3D scanning, body postures, and landmarking techniques to complete in-depth analyses of skin deformation, measurement change, and shape change of the waist-hip-thigh region of the body. There is a need to develop and test new integrated measurement analyses using 1D, 2D, and 3D data to quantify how and where the body is changing in different postures. An integrated approach was taken to select the appropriate 3D scanning technology, develop a landmarking method, and position the body to analyze the waist-hip-thigh region. A convenience sample of 11 women participated in the pilot study, ranging in age from 41-73. Using a quadrant landmarking technique, the body was divided into sections to locally analyze 1D and 2D measurements, while conducting volume and curve analysis to aid our understanding of shape change. Local percent change of each circumference was significant, and the data across the various measurements captured the expansion and shrinking of the body. Additionally, the 1D, 2D, and 3D analysis of the models shows the body deforming differently based on participant size, indicating this type of data could be critical for improved size system creation. The results from the extraction of curves represents exciting frontiers in 3D shape research and in the future will enable shape to be more easily incorporated into wearable garments. This data can improve the development of materials, trims, pattern design, and sizing systems. New 3D scanning methods to quantify diverse bodies can improve a company's competitive advantage through enhanced product fit and inclusive, quality design for all.

Sportswear is based on sizing tables developed on a basis of average body sizes and will therefore not fit population groups with body proportions categorically different from average (e.g. athletes from different sport disciplines, disabled people or people with specific professions). This is not only detrimental for the aesthetics and comfort of the wearer but also in stark contrast with functionality (e.g. orthopedic products; sportswear meant to offer some support, to improve performance or to facilitate fast revalidation; some intelligent textiles for monitoring) and the changing demands of the consumers who lose their tolerance for regular products and have become more and more demanding for garments with a personalized fit. These groups of products require an optimal contact with the skin, they have to fit, otherwise they lose their functionality. The overall objective of the project Adapted Performance Sportswear is to develop comfortable, fitted and functional (sports)wear for population groups with body shapes and proportions different from the average population. The aim of the project is to gain better insight in anthropometric differences (average population versus various groups of athletes) and work out a methodology for translating this information effectively to the garment production. The concept of compression, support and restriction of certain movements by employment of new and innovative elastic materials will be further explored in relation to the fit.

“…The skin deformation changes depending on the lower-limb movement and its measurement can give an indication of the muscle activity. Several researches [19,20] provided a detailed skin deformation mapping only during the knee flexion. In fact, the measurement of the skin deformation is quite complex since contraction and extension of the skin is not the same along the same body segment.…”

Multisensor System for Analyzing the Thigh Movement During Walking

Abstract-Body movements monitoring may allow preventing, diagnosing, and recovering several wrong attitudes that could lead to possible future diseases. A multi sensor system was developed to measure thigh movements in free-living environments all-day long especially during walking. The device is a very simple and portable system based on low-cost technology. It is composed of an inertial sensor and a strain sensor for detecting thigh movements, and of a microcontroller and a Bluetooth module. The measurement data are collected and sent wirelessly to a PC for storing and further analyses. We validated and tested the wearable system on 10 healthy subjects during walking and running by using an accurate inertial motion capture (Mo-cap) system. The inclination of the thigh measured by the proposed system has differed of maximum 5.5° with respect to the flexion/extension measured by the Mo-cap system. Furthermore, the experimental results have showed that the strain sensor output can also be related to the muscle activity during walking. This assumption has further been sustained when the system is tested during running. Thanks to its high wearability, wireless communication over long distances and long-battery life, the system could be adopted for domestic applications.Index Terms-strain sensor, inertial sensor, wearable sensor, wearable electronic device.
