Some products are not designed with people of color in mind. As more products are created with the implementation of technology, it is important that they are designed for the population at large including Black Indigenous People of Color (BIPOC) populations. User Experience Design (UXD) is the process employed by designers to create products whose goals are to make purposeful and significant experiences for users. In UXD, personas are fictitious characters to represent the user. They are tools that represent what designers learn during research about potential customers and populations that might use products, websites, or services. They also serve to help designers and engineering teams focus on user values, as well as understand possible user constraints and limitations. To assure that their personas reflect evolving consumer base demographics, it is important that products are created for a diverse population. While existing research has focused on gender and sexuality when it comes to defining the identity of the user with an intersectional lens, there has been less of a focus on the equally important race and ethnicity of the user. Intersectionality, defined by Professor Kimberle Crenshaw, involves "Understanding the ways that multiple forms of inequality or disadvantage sometimes compound themselves and create obstacles that often are not understood in conventional ways of thinking". Crenshaw first articulated her theory of intersectionality to foreground critiques by Black feminists that the discrimination they faced compared to White women was amplified due to race. Intersectionality asserts that race, gender, sexuality, class, and other factors all impact each other when it comes to the representation of the user in HCI and UXD. This research focuses on identifying, evaluating, and proposing two persona creation processes by introducing race, ethnicity and intersectionality for UX designers in three phases. Phase 1 consisted of an investigative study where the online portfolios of 127 UX designers were surveyed to better understand the relationship between UX designers and the personas they create. After analyzing the data, most UX designers created personas that were closely related to themselves, with very little deviation from this norm. With the realization that 70% of UX designers are White, that only 3.5-5% of UX designers are Black/African American and a mere 12% identify as LGBT, an intersectional approach is suggested as the solution to the bias of UX designers when creating personas. Phase 2 consisted of reviewing the HCI and UXD literature to examine how the literature sees, or fails to see, the user and the Intersectionality of their identity when it comes to race and ethnicity. Most of the research on the intersectional representation of the user has focused on gender, and then class. This study asked how the emerging literature on race and ethnicity in UXD and HCI might be applied to educate the future generation of UX designers on the common design errors found in technology in relation to the race and ethnicity of the user. This work led to the development of a syllabus that will lead future designers to develop more inclusive personas by gaining greater insights of intersectional identity representation. Phase 3 used interviews, program curriculums, and syllabi analysis as part of a collective case study involving 15 graduate HCI programs to identify if and how race, ethnicity and intersectionality are introduced across the landscape of UX design graduate education with an eye toward whether these topics were covered in their curriculum, and if so, where and how. The results of this investigation guided the creation of a pedagogical approach to introducing these topics into the classroom based on a Constructivist learning framework, with an intersectional lens focused most closely on race and ethnicity, to teach persona creation to UX designers at the graduate levels. Overall, this research gave in-depth documentation of the lack of awareness on issues around race and ethnicity and how this can have a negative effect on the user. This inadequacy resides among UX designers and HCI curriculums. Finally, this research adds to the emerging literature on the importance and value of intersectionality in HCI when it comes to the representation of the user. It also provides UX design educators in graduate programs with modules to implement race and ethnicity with an intersectional lens to the persona creation process to their curricula.
