Designing Inclusive Interfaces for DHM Applications Addressed to Fragile Users

Digital Human Modeling is the science of the representation of human beings and of their physical properties, characteristics and behaviors, in virtual models. This technology is successfully used as a tool to simulate the relationship between the person and parts of the environment, to simulate certain conditions and make a prediction about safety and performance. Current applications of Digital Human Modeling are spreading in various fields, such as automotive and space, fashion, industry, health science and medicine, but although this technology has existed for several years, its many application possibilities are still being explored. When Digital Human Modeling applications are addressed to interfaces for final users, the design process needs to consider their aspirations and requirements to be successful. In particular, inclusive design principles and tools can enhance the possibility to achieve a significant enlargement in the number of users with a performance limitation, that can anyway take full advantage of the designed product or service. Designing accessible and usable interfaces for users with cognitive or motor impairments require some precautions, especially the possibility of personalization in relation with the personal health conditions. The current paper wants to explore possibilities and limitations of digital human models applied to Human Centered Design with inclusive purposes. Specifically, the author aims to analyze possible difficulties of users presenting performance limitations in enjoying interfaces of digital services.
