the Garment protection factor gpf an index for sun protective clothing that combines Garment coverage and uvr transmittance
2018Co-Authors: Simone L. Harrison, Alex Rawlings, Nathan Downs, Alfio V. ParisiAbstract:Introduction: Clothing provides a protective barrier that reduces the amount of ultraviolet radiation (UVR) reaching the skin. Industry standards for sun-protective clothing have been implemented in Australia/New Zealand, Europe, and the USA. However, ratings and labelling used for clothing marketed as sun-protective do not routinely communicate the importance of Garment coverage, although evidence suggests that this may be as important in preventing skin damage as the UVR-transmittance of the fabric. We propose a new index for sun-protective clothing called 'the Garment Protection Factor (GPF)' which considers both the body surface area (BSA) covered by a Garment and the Ultraviolet Protection Factor (UPF) of the fabric from which it is made. Methods: Manikins (range of sizes and ages) were fixed to an optical bench and marked with horizontal lines at 1 cm intervals. The GPF algorithm was developed based on the number of lines visible on clothed versus unclothed manikins and the UPF of the Garment fabric. Results: The GPF weights fabric UPF by the BSA-covered above the minimum specified in international sun-protective clothing standards for upper-body, lower-body and all-in-one Garments. GPF increases with BSA-covered and UPF. Three nominal categories are proposed: 0 ≤GPF<3 for Garments that 'meet' minimum standards; 3 ≤GPF< 6 for Garments that provide 'good' sun-protection; and GPF ≥6 for Garments that provide ‘excellent’ protection. Conclusions: The proposed GPF provides a means by which Garment design (in terms of proportion of skin covered) and fabric UPF can be reported in a single index. Adopting the GPF would encourage manufacturers to design sun-protective Garments that exceed the minimum standard for BSA-coverage. The research may also assist efforts to standardize the evaluation and labelling of sun-protective clothing across global markets, with positive implications for consumer awareness and skin cancer prevention world-wide.

A comprehensive approach to evaluating and classifying sun-protective clothing.
British Journal of Dermatology, 2018Co-Authors: Nathan Downs, Simone L. HarrisonAbstract:Background: National standards for clothing designed to protect the wearer from the harmful effects of solar ultraviolet radiation (UVR) have been implemented in Australia/New Zealand, Europe, and the USA. Industry standards reflect the need to protect the skin by covering a considerable proportion of the potentially exposed body surface area (BSA) and by reducing UVR-transmission through fabric (the Ultraviolet Protection Factor; UPF). Objectives: This research aimed to develop a new index for rating sun-protective clothing that incorporates the BSA coverage of the Garment in addition to the UPF of the fabric. Methods: A mannequin model was fixed to an optical bench and marked with horizontal lines at 1 cm intervals. An algorithm (the Garment Protector Factor; GPF) was developed based on the number of lines visible on the clothed versus unclothed mannequin and the UPF of the Garment textile. This data was collected in 2015-16 and analysed in 2016. Results: The GPF weights fabric UPF by BSA coverage above the minimum required by international sun-protective clothing standards for upper-body, lower-body and full-body Garments. GPF increases with BSA coverage of the Garment and fabric UPF. Three nominal categories are proposed for the GPF: 0 ≤ GPF < 3 for Garments that 'meet' minimum standards; 3 ≤ GPF < 6 for Garments providing 'good' sun-protection; and GPF ≥ 6 indicating 'excellent' protection. Conclusions: Adoption of the proposed rating scheme should encourage manufacturers to design sun-protective Garments that exceed the minimum standard for BSA coverage, with positive implications for skin cancer prevention, consumer education and sun-protection awareness.

towards a Garment os supporting application development for smart Garments
International Symposium on Wearable Computers, 2014Co-Authors: Stefan Schneegass, Mariam Hassib, Tobias Birmili, Niels HenzeAbstract:Wearable devices and the development of smart Garments emerged into a significant research domain over the last decades. Despite the increasing commercial interest, however, smart Garments are almost exclusively developed in academia and the developed systems do not exceed a prototypical level. We argue that the main reason why smart Garments cannot be produced on commercially relevant scale today is that they each focus on a specific use case. There is no tool support for application developers and no defined APIs within the software and hardware stack that allows developing useful smart Garment applications. In this paper we present our work towards Garment OS, a layered software stack that encapsulates different levels of abstraction. We highlight the design of that system which is based on open web protocols. We present an evaluation with software engineers and derive directions for future work.

learning a shared shape space for multimodal Garment design
ACM Transactions on Graphics, 2018Co-Authors: Tuanfeng Y Wang, Duygu Ceylan, Jovan Popovic, Niloy J MitraAbstract:Designing real and virtual Garments is becoming extremely demanding with rapidly changing fashion trends and increasing need for synthesizing realisticly dressed digital humans for various applications. This necessitates creating simple and effective workflows to facilitate authoring sewing patterns customized to Garment and target body shapes to achieve desired looks. Traditional workflow involves a trial-and-error procedure wherein a mannequin is draped to judge the resultant folds and the sewing pattern iteratively adjusted until the desired look is achieved. This requires time and experience. Instead, we present a data-driven approach wherein the user directly indicates desired fold patterns simply by sketching while our system estimates corresponding Garment and body shape parameters at interactive rates. The recovered parameters can then be further edited and the updated draped Garment previewed. Technically, we achieve this via a novel shared shape space that allows the user to seamlessly specify desired characteristics across multimodal input without requiring to run Garment simulation at design time. We evaluate our approach qualitatively via a user study and quantitatively against test datasets, and demonstrate how our system can generate a rich quality of on-body Garments targeted for a range of body shapes while achieving desired fold characteristics. Code and data are available at our project webpage.
