Scan posture definition and hip girth measurement: the impact on clothing design and body scanning
Ergonomic measurement is central to product design and development; especially for body worn products and clothing. However, there is a large variation in measurement definitions, complicated by new body scanning technology that captures measurements in a posture different to traditional manual methods. Investigations of hip measurement definitions in current clothing measurement practices supports analysis of the effect of scan posture and hip measurement definition on the circumferences of the hip. Here, the hip girth is a key clothing measurement that is not defined in current body scanning measurement standards. Sixty-four participants were scanned in the standard scan posture of a [TC] 2 body scanner, and also in a natural posture similar to that of traditional manual measurement collection. Results indicate that scan posture affects hip girth circumferences, and that some current clothing measurement practices may not define the largest lower body circumference. Recommendations are made concerning how the hip is defined in measurement practice and within body scanning for clothing product development. Practitioner Summary: The hip girth is an important measurement in garment design, yet its measurement protocol is not currently defined. We demonstrate that body posture during body scanning affects hip circumferences, and that current clothing measurement practices may not define the largest lower body circumference. This paper also provides future measurement practice recommendations
3D body scanning in the apparel industry: Do we really know where we are heading?
This paper through - the Diffusion of Innovation
Model - shows
that while 3D Body Scanning brings some refining and improvements of existing
methods, it does not introduce new concepts that depart from traditional retail
practices. 3D Body Scanning is - potentially -
a powerful way of approaching size and fit in apparel and one that presents
novel opportunities. Yet, despite the advantages that this technology offers,
and the many initiatives that have taken place, 3D Body Scanning has not reached
its full potential and has failed to produce the expected
results held by many stakeholders. Stakeholders must increase collaboration to
realise 3D Body Scanning’s relative advantage. Much of the potential has, however, been promoted by distinct
organisations that are biases about how the diverse processes and structures
will work together, whilst focussing on profit from their own incremental IP.
In this paper we elicit 3D Body Scanning’s fundamental concepts, and its central goal to
provide ‘glue’ needed to create an innovation. We offer further implications
for researchers
and policymakers about expecting and managing trends in technology. <br
Online virtual fit is not yet fit for purpose: An analysis of fashion e-commerce interfaces
To unify the methodology of Virtual Fit platforms and allowing cross platform integration of 3D Body Scanning, the current Virtual Fit platforms need to be assessed in terms of their size recommendation approach and user interaction. Digital data, interactivity, and internet technology are changing the ways we interact in online shopping, with the Virtual Fit platforms having great potential to increase retail engagement and market share. This will support online purchasing activities while minimising the perceived risk in garment returns due to the poor sizing fit information. Current research has focused on the analysis of computer modelling techniques, avatars, cloth, fabric draping simulations, and customer behaviour / aesthetic impact in the online domain. From a technical perspective, these investigations offer an interesting insight, although do not address issues of implementation or customer attitude. Therefore, to judge the current and potential impact of such technologies, it is important to understand 1) how they are being enacted online, 2) the Interaction Design elements of the user journey, 3) the application (or lack thereof) of mathematical models, and 4) how such interfaces are embedded within websites. Once these four key questions have been answered a greater understanding of how 3D Body Scanning and Technologies integrated into eCommerce and Virtual Fit platforms in the consumer market may be reached. Through analysis of nine leading Virtual Fit platforms, the persona of a single female dress form was used to work through the customer journey. Through this, screen shot data captured along each stage in relation to the four research questions listed above. Following this, the study utilised content analysis structure with NVivo as a qualitative thematic analysis tool. This study found that despite a large number of platforms using virtual fit technology, only a handful companies exist that provide such technology and interfaces; often based upon subjective ‘previous purchases’ rather than scientific prediction. This issue is made more complicated in how subjective measures such as personal perception of one’s body is required (e.g. what size are you), besides body shape; a concept shown to be ‘broken’ and not fit-for-purpose. In addition, many of the technologies use limited and often misinterpreted body measurements, the impact of which is explored in greater detail within the paper. This study contributes to the understanding of the information required from users by virtual fit platforms, and the understanding of the output as presented by virtual fit platforms. The research goal is to contribute to knowledge as a potential guideline for any future projects in virtual fit and to help direct body scanning developments to better support these platforms
Assessing the female figure identification technique’s reliability as a body shape classification system
This paper demonstrates the effects of small differences in measurement definitions on resultant body shape classification. Ergonomic researchers consider the Female Figure Identification Technique (FFIT) a ‘gold standard’ body shape classification system to describe variation in a population’s 3D profile. Nevertheless, researchers use FFIT without scientific basis or considering their ergonomic suitability. This paper rigorously evaluates FFIT, focusing on ergonomics, garment construction, and scientific research applications. Through analysing 1,679 3D Body Scans, we assess the level of agreement between the FFIT’s body shape classification when measurements placed following FFIT’s or SizeUK’s guidance. We establish how different interpretations of FFIT’s measurement placement cause the same body to be categorised into different shapes - in up to 40% of cases. FFIT omits shoulder measurements that have little relationship to body shape yet are vital in garment construction. Using FFIT with different dataset and definitions, therefore, leads to inconsistent conclusions about shape differences
A method for increasing 3D body scanning’s precision: Gryphon and consecutive scanning
The fashion industry cannot use 3D Body Scanning to create custom garment patterns because its measurements fail to meet ISO 20685:2010’s tolerances. To advance 3D Body Scanning’s precision, we present Gryphon: an algorithm that removes the two most extreme measurements from five body scans; removing potentially erroneous data. We assess Gryphon’s precision against current industry practice, determine if consecutive and non-consecutive data capture influences precision, and determine 3D Body Scanning’s inherent imprecision inherent. We analyse 97 participants over 121 industry-standard measurements for consecutive and non-consecutive data-capture through MANOVA statistical analysis. Under current industry practice, only one measurement meets ISO 20685. However, under Gryphon and consecutive scanning, 97.5% of measurements meet ISO 20685. We also prove that the body’s in-scan movement does not affect reliability. Ultimately, we offer the fashion industry, ergonomists, and practitioners an accessible method to increase 3D Body Scanning’s precision at a level unavailable under previous methods
