Retinitis Pigmentosa (RP) is an eye disease that affects 1 in 4.000 people and it causes the loss of peripheral vision in early stages, possibly leading to blindness at its final stage. Currently, there is no known treatment or procedure that provides a final cure, even with the use of stem cells or micro-sensor implants on the retina. Patients with RP have their night vision impaired, as well as difficulty in depth, focus, and clarity as a result of RP and other concomitant diseases such as myopia and cataracts. This paper proposes a technology to support people with Retinitis Pigmentosa. It is a software application for mobile devices that offers specific functionalities, such as, camera zoom, object detection, object tracking, face detection, person tracking, sharper images, and speech interaction. In addition to these, it is possible to obtain information regarding the emotional state with the processing and automatic detection of faces, which enables the carrier of RP to interact more naturally with the people in his surroundings. The proposed system also enables the mobile device to be used in a smartphone holder acting as glasses, making it a wearable technology. In the proposed solution, the Android Platform with the OpenCV technology was used. Usability tests have been made and the results demonstrated that the proposed technology can be useful and functional. In addition, there are many other possibilities for the use of a smartphone, such as, adding an extra camera as well as motion interfaces. This technology solution is one that can be accessible by many RP users, given the choice of the android mobile platform.
