| Sumario: | People with visual impairments have difficulties in navigating indoor spaces and identifying elements of interest in the environment. There are a plethora of assistive systems that address this problem, but most of them are either expensive, depend on specialized hardware or lack intuitiveness. VIP SpaceNav is a platform for low-cost, intuitive configuration and safe navigation, intended for people with visual impairments. The system's content management system stores a 3D model of the building, together with localization information and elements of interest. The mobile application dedicated to users with visual impairments runs a localization component, as well as an obstacle detection module, providing navigation cues and information about points of interest in the vicinity, with the help of text-to-speech and audio signals. This paper presents a concept of indoor guidance for people with visual impairments and a first materialization of the prototype, based on state-of-the-art localization and spatial sounds. It also describes the piloting of the system in complex scenarios in a real building, demonstrating its potential of deployment in any indoor space, with minimal financial and time resources. IMPLICATIONS FOR REHABILITATION: VIP SpaceNav is a platform for low-cost, intuitive configuration and safe navigation, intended for visually impaired people. The mobile application dedicated to visually impaired users provides navigation cues and information about points of interest in the vicinity, with the help of text-to-speech and audio signals. With VIP SpaceNav, any building can become an accessible location for VIPs, where the position and route to any element of interest is indicated.
