GraVVITAS 2.0: a framework for digital accessible content provision

Research output: Chapter in Book/Report/Conference proceedingConference PaperOther


Access to information is a fundamental problem for people with vision impairment (PVI). Textual information are considerably more accessible with the use of screen readers that work on desktop and mobile devices. However, access to graphical information is still a challenging problem. There are different technologies to present graphics to PVI, but almost all of them suffer from practicality and portability. This paper describes the GraVVITAS (Graphics Viewer using Vibration Interactive Touch and Speech) framework which aims to be a complementary system for other assistive technologies; a solution that can be carried in one's pocket.
