A Comparative Study of the Learning Curve of a Novel Interface for the Deafblind: Implications for Educational Environments

Nicholas Caporusso, Giovanni Perrone

Abstract

In addition to communication and mobility issues, the blind and the deafblind suffer from poor social inclusion. This is particularly due to scarce literacy and lack of access to adequate educational resources. In this paper, we introduce dbGLOVE, an innovative and low-cost wearable interface based on a tactile communication system especially designed for the deafblind. We compare the performances of dbGLOVE with the state-of-the-art technology for the blind and the deafblind, i.e., the Braille display. Results from our study show that dbGLOVE has a faster learning curve, and it outperforms the Braille display both in accuracy and in speed. Finally, we discuss the implications of our findings and we detail the features that render dbGLOVE particularly suitable for educational purposes.
