Rehabilitation engineering seeks to develop technologies that help people with some form of disability to alleviate their limitations, improving their quality of life. Visually impaired people have serious difficulties in urban mobility since most of the traffic signaling is based on vision. In this sense, this work proposes the construction of a device to assist the visually impaired to identify the state of urban traffic lights through touch. For this, a device will generate vibration patterns that can be interpreted as being different states of the traffic lights. A simulator was built as proof of concept of this technique. This work presents details of the construction of this simulator.
