Toward tactile authentication for blind users
Ravi Kuber, Shiva Sharma · 2010
This paper describes the design of an accessible authentication mechanism. The Tactile Authentication System has been adapted to enable individuals who are blind to access electronic data using their sense of touch. To enter the system, users must identify a set of pre-selected pin-based icons from a wider range presented via a tactile mouse. As information is presented underneath the user's fingertips, 'tactile passwords' are shielded from observers, thereby enhancing security from third-party attacks. Results from a pilot study showed that five participants were able to authenticate entry to the non-visual interface over the course of a two week period. However, findings have revealed that the time needed to perform this process should be reduced to improve the quality of the user experience.
