    The Influence of Human Factors and Ergonomics on Data-Driven Design Criteria for a Handheld Skin Screening Camera System
    (2020-08) Bornstein, Alexandra
    This study is an extension of ongoing research conducted at the Minneapolis VA Health Care. The original study included the development of a long-handled camera system to support skin screening. This project aimed to develop an effective handheld skin screening camera system using human factors and ergonomics (HFE) centered design criteria. This skin screening camera system resulted in the form of a look- and feels-like prototype model to support preventative skin care for persons with spinal cord injuries (SCI) and persons with diabetes mellitus (DM). Each of these populations are at risk of developing wounds such as pressure injuries (PIs) or diabetic foot ulcers (DFUs). The proactive ability to identify wounds in the early stages (a reddened area) and thus prevent further development of these injuries not only reduces financial burden but can also increase the sense of independence and psychosocial wellbeing. This study was conducted with four study participants from SCI and four from DM populations through the Minneapolis Veterans Affairs Health Care System. Using HFE-focused data collection with study participants provided a blueprint for the design and development of the Phase Two prototype. This enhanced user experience through ease of use, dimensions, adjustability, safety and security, comfort, and overall effectiveness of the device. The Phase Two prototype design received an overall satisfaction rating of 4.69 out of 5 (between quite satisfied and very satisfied) from study participants. The results of the study indicated that other design features could be implemented to improve the usability of the device. This includes consideration of how the product would be manufactured, development of the mobile device application, and accommodating user needs.
