Blocks-based programming environments are a popular tool to teach children to program, but they rely heavily on visual metaphors and are therefore not fully accessible for children with visual impairments. We evaluated existing blocks-based environments and identified five major accessibility barriers for visually impaired users. We explored techniques to overcome these barriers in an interview with a teacher of the visually impaired and formative studies on a touchscreen blocks-based environment with five children with visual impairments. We distill our findings on usable touchscreen interactions into guidelines for designers of blocks-based environments.
