This article explains the development of the Uitsiton system, capable of detecting obstacles to alert visually impaired users, increasing their mobility and confidence when moving. Uitsiton is made up of a portable electronic device (wearable) and a mobile application (App) that operates under the Android platform. The wearable is integrated into a vest-like garment. It is used to compute the approximate distance between the visually impaired user and the obstacles that they can find in their path. The wearable covers a range of 180 degrees vertically and horizontally with respect to the center of the torso, and reaches a maximum distance of 120 cm. The App works synchronously with the wearable, it receives a series of data corresponding to the measurements of the distance between the user and the obstacle, and it triggers a sound pattern and a vibration pattern according to the proximity of the obstacle.
