This paper presents a system developed in the context of a final project of Licenciatura in electronics and telecommunications at ISEL. The Project offers the ability to detect objects that are at head height of a blind user. The obstacle’s detection is supported on ultrasound signals and the communication with the user is made through vibrating motors, placed around the waist, giving him the sense of the obstacle’s location. This way, besides protecting the user against potential targets, it’s also providing an intuitive reference of the surrounding area.
