This thesis presents a tangible cooperative distance learning environment via a custom set of Trackable Interactive Multi-modal Manipulatives (TIMMs). This work defines a platform empowering people with visual impairments to create, modify, and naturally interact with mathematical graphs. TIMMs are designed to enable distance cooperation among sighted and BVI (Blind and Visually Impaired) students including instructors. This system enables distance learning and sharing of special education teachers to help alleviate shortage of instructors in rural areas. This system supports remote and active stacking, and position tracking of manipulatives on a table-top surface, while providing complete visibility to local and remote instructors and students. This user-centered design is derived from various visits and discussions with instructors of blind and visually impaired students in K-12. This thesis also proposes a classification and comparison of existing TUIs designed for BVI to present a structured overview of current research via a novel framework and make suggestions for future work in this area.
