Breaking barriers: Ruzimi demonstrating how his educational e-book works using augmented reality technology. — THOMAS YONG/The Star IT takes a lot of grit, perseverance and motivation to excel in something, more so for those with disabilities. Born without both legs and left arm, Dr Ruzimi Mohamed @ Mahmood defied the odds to complete his tertiary education and start his own business — providing training and products related to the needs of the disabled. Since kicking off his business in 2010, the 36-year-old with a PhD in Computer Science and his team of seven have produced a series of physical materials and e-books that teach Malaysian Sign Language in an interactive manner using augmented reality (AR) technology.
