Abstract

In the context of improving quality of life and inclusion, the development and implementation of technologies aimed at assisting people with visual impairment has emerged as an area of interest and is constantly evolving. The objective of this article is to review the technologies implemented worldwide that facilitate the mobility of individuals with visual impairment in outdoor environments. To achieve this objective, the PRISMA methodology was employed, and variables such as the study environment, platform/device utilized, sensors and components, services and APIs, among others, were established. The analysis of the selected research revealed a trend towards the use of assisted technologies, image processing, and machine learning. Furthermore, it was recommended that future work include the implementation of artificial intelligence and the creation of open-source environments to encourage greater community involvement in the development process. It was determined that the majority of the proposals analyzed are oriented towards the individual, rather than the social level. Consequently, the necessity to adapt these solutions to the specific social context of Colombia is emphasized.
