Blind subjects faces database

Using your face to unlock a mobile device is not only an appealing security solution, but also a desirable or entertaining feature, such as taking selfies. It is convenient, fast, and does not require much effort, but only if you have no vision problems. For users with visual impairments, taking selfies could potentially be a challenging task. In order to study the usability and ensure the inclusion of mobile-based identity authentication technology, we have collected the Blind-Subjects Faces Data Base (BSFDB). Ensuring that technology is accessible to disabled people is important because they account for about 15% of the world population. The BSFDB database contains several individuals with visual disabilities who took selfies with a mock-up mobile device. The experimental settings vary in the image acquisition process or experimental protocol. Four experimental protocols are defined by a dichotomy of two controlled covariates, namely, whether or not a subject is guided by audio feedback and whether or not he/she has received explicit instructions to take the selfie. Our findings suggest that the importance of appropriate design of human computer interaction as well as alternative feedback design. The BSFDB database can be used to investigate topics such as usability, accessibility of the face recognition technology, or its algorithmic performance. All the gathered data is publicly available online including videos of the experiments with more than 70,000 face images of blind and partially blind subjects
