A mobile application that detects an item’s color is potentially very useful for visually impaired people. However, users could run into difficulties when centering the target item in the mobile device camera field of view. To address this problem, in this contribution we propose a mobile application that detects the color of the item pointed by the user with one finger. In its current version, the application requires the user to wear a marker on the finger used for pointing. A preliminary evaluation conducted with blind users confirms the usefulness of the application, and encourages further development.

Abstract
A mobile application that detects an item’s color is potentially very useful for visually impaired people. However, users could run into difficulties when centering the target item in the mobile device camera field of view. To address this problem, in this contribution we propose a mobile application that detects the color of the item pointed by the user with one finger. In its current version, the application requires the user to wear a marker on the finger used for pointing. A preliminary evaluation conducted with blind users confirms the usefulness of the application, and encourages further development.File | Dimensione | Formato | |
