Food insecurity, an economic and social condition where households have limited access to nutritious food, is a long-standing and growing problem in both the rural and urban areas of the United States. Food deserts refer to areas that do not have adequate food access to affordable and nutritious food. Food deserts can be characterized by availability, accessibility, accommodation, affordability, and acceptability (5A’s). This research investigates food deserts in Mecklenburg County, North Carolina, which includes the city of Charlotte. The food insecure population estimate in Mecklenburg County is about 15% which is higher than the national average of 11%. Using visual analytics, a combination of analytics and human factors, this study aims to examine how age, education, and income are related to food deserts in Mecklenburg County.

BACKGROUND: Today, various emerging assistive applications (apps) running on smartphones have been introduced such as Seeing AI, TapTapSee, and BeMyEyes apps. The assistive apps are designed to assist people with visual impairment in navigating unfamiliar environments, reading text, identifying objects and persons. Yet, little is known about how those with visual impairment perceive the assistive apps. OBJECTIVE: This study aims to advance knowledge of user experience with those assistive apps. METHODS: To address the knowledge gap, this study conducted phone interviews with a convenience sample of 30 individuals with visual impairment. RESULTS: The results indicated that those with visual impairment showed a range of preferences, needs, and concerns about user interfaces and interactions with the assistive apps. DISCUSSIONS: Given their needs and concerns, this study offered a set of facilitators to promote user adoption of the assistive apps, which should be valuable guidance to user interface/interaction designers in the field.more » « less
