This work proposes the study and design of mobile interfaces to identify the position and orientation of blind people in closed environments. Through this development we seek to reach a consensus on the use of a certain technology that would allow for the identification of the position and orientation of people within a closed space (such as a school or home) with the necessary infrastructure. A focus group was held in order to identify the users’ problems with the navigation. In addition we made initial and final usability tests. The results of the usability evaluation showed that the interface designed was highly usable for blind users and that the technology designed worked to improve the indoor navigation of blind people.
