Supermarkets have a dynamic environment, which use visual signals to influence the purchase and consumer behaviour. Visually impaired people, unable to interpret these signs end up losing autonomy to make purchases and resort to the help of others to shop. This study has two objectives: First, understand the experience of these consumers in the supermarket and understand how they shop; Second, develop an App with sensors, to identify and locate products in supermarkets. We adopted a qualitative methodology, through online surveys to analyse consumer behaviour, with the data analysed by Leximancer. The answers allowed to define the ideal functionalities, identified in a conceptual map aggregated in 4 themes (Read, Application, Supermarket and Products), to be considered in the development of an application that helps people with visual impairments to shop. The present study contributes to the establishment of possible guidelines for requirements and the development of applications for the visually impaired.
