Abstract This work aimed to make the repetition of the experiment performed by Dosono et al [1], which studied how the current authentication interfaces pose significant burden to visually impaired persons. We revealed that previously found difficulties such as locating authentication area, verifying the success of authentication, and use of visual/voice authentication, were reproducible in a set of users with different demography. In addition, our participants enabled us to add another dimension – age – to our study. We found that younger visually impaired users can outperform elder nonvisually-impaired users. The fact indicates that accessible design should address not only blindness factors but also aging factors.
