Blocks4All

An accessible touchscreen-based block-based programming environment designed for students with visual impairments. Blocks4All enables drag-and-drop-like programming interactions on touchscreen devices with screen reader support, making it one of the few on-screen block-based environments accessible to blind and low-vision students. The system is designed to work with the DASH robot, providing tangible output that students can hear and feel as their programs execute. Blocks4All is undergoing expansion to include additional functionalities beyond its initial robot-programming focus.
