According to the World Health Organization in 2021, approximately 2.2 billion people are blind or have visual impairments. People who are blind or have low vision (B/LV) rely on assistance from others as well as from assistive technology to complete many everyday tasks, which require visual sensory information.We initially conducted a survey of devices for people who are B/LV which focused on the information communicated to the user through different feedback methods and the tasks these devices are designed to assist people with. After discovering a need for object finding devices in our survey, we distributed a questionnaire to local agencies for people who are B/LV. Our first questionnaire focused on learning about assistive devices that are commonly used by this population, as well as challenges that they face while shopping. From this questionnaire, we found that there is a need for a device to assist with various tasks while shopping, including navigating to desired products and reading information on labels. We then expanded upon the initial survey of devices to investigate the sensor packages used for indoor and outdoor sensing. Next, in a follow up questionnaire, we asked questions to gather feedback on our initial design plans for this device including how beneficial they thought it would be, how the device should communicate information to them, and any privacy concerns they had with sharing data to build a map shared between users.The system that we designed and implemented uses a smartphone and its built in sensors to provide shopping assistance, primarily using speech. Labels are read to identify products and to provide answers to questions users may ask regarding the products. Simultaneous Localization and Mapping (SLAM) is used to map the stores and provide navigation instructions to users. These maps are community updated, where all devices contribute data to ensure that the maps are kept up to date.
