    Analysis of body armor fit and comfort using 3D body scanning: a case study with an industry partner
    (Colorado State University. Libraries, 2018) Conroy, Brittany L. W., author; Park, Juyeon, advisor; Li, Yan, committee member; Hess, Ann Marie, committee member
    This study adopted a single case study approach to evaluate the fit and comfort of a company's body armor product, and improve the design of the product. To achieve this goal, I developed a mixed-methods strategy driven by the co-design paradigm and operated it in the three-stage product development process. A total of 13 individuals including five police officers and seven company employees participated in the study as collaborators for the product evaluation and development process. The police officers –actual users of the product – were recruited as external collaborators through the case company, and asked to participate in a series of data collection methods including the pre-survey, 3D body scanning, occupational task analysis, and exit interviews to provide holistic user feedback on the product. The company employees – developers of the product – were interviewed to share the insider's perspectives as internal collaborators. As results, key areas of interaction between the body and the vest were identified during Stage 1 (Problem Definition and Research), which subsequently informed the creative design and prototyping process in Stage 2 (Creative Exploration and Evaluation). During Stage 3 (Implementation), final recommendations and plans for implementation were developed with the case company. The outcome of this research is expected to benefit the case company who manufactures the body armor product, as well as police officers who wear it in the line of occupational duty, as the resulting product will offer better fit for their body and be more comfortable to wear.

    Identifying fit issues for the one-size-fits-all hospital patient gown: an anthropometric approach
    (Colorado State University. Libraries, 2015) Jankovska, Daniela, author; Park, Juyeon, advisor; Ruoh-Nan, Yan, committee member; Greene, David, committee member
    The purpose of this study was to identify fit issues associated with the hospital patient gown in order to facilitate a better fit and comfort of the hospital patient gown to as many potential patients as possible. To address the research questions, this study adopted a multi-dimensional fit and comfort evaluation protocol that consisted of a survey, 3D body scanning, scenario activities, and exit interview. Eighty-five participants (47 males and 38 females) participated in this study. The exploration of the fit and comfort of the hospital patient gown across gender, diverse age, and different BMI categories revealed three major issue that must be taken into consideration in order to achieve an the best fit and size for the hospital patient gown: (a) consideration of sensory clothing preferences and hospital patient gown design preferences, (b) 3D body measurements and (c) accommodation to common daily activities such as, walking, lying, bending, reaching up and sitting during hospitalization. Three-dimensional body scanning data identified the following anthropometric body landmarks that caused fit problems: neckline, shoulders, sleeves and armholes, bust/chest, abdomen and stomach, hips and knee circumference. The findings of the study suggest that there are major fit issues with the conventional hospital patient gown, which must be adequately addressed to provide its wearers with acceptable satisfaction with the fit of the gown.
