This work-in-progress presents our prototype of a tangible collaborative distance learning environment via a custom set of Trackable Interactive Multi-modal Manipulatives (TIMMs). This work defines a Tangible User Environment (TUE), empowering people with visual impairments to create, modify, and naturally interact with graphical representations that are commonly encountered in mathematics, computer science and other scientific disciplines. TIMMs are designed to enable distance collaboration among students and with instructors. This system supports remote and active position, proximity, stacking, and orientation tracking of manipulatives on a multi-touch table-top surface, while providing complete visibility to local and remote instructors. This user-centered system design is derived from various visits and discussions with instructors of blind and visually impaired students in K-12 education.

“…Physical visualizations can also increase the accessibility of data to blind or low-vision users [3,7,19,24]. Examples include tactile pin arrays to show graphics [39], VizTouch [3] that allows blind users to 3D print visualizations of line graphs, and tactile maps [27] that show cartographic data using physical properties (physical height corresponds to elevation of the terrain).…”

Visualizations such as bar charts help users reason about data, but are mostly screen-based, rarely physical, and almost never physical and dynamic. This paper investigates the role of physically dynamic bar charts and evaluates new interactions for exploring and working with datasets rendered in dynamic physical form. To facilitate our exploration we constructed a 10×10 interactive bar chart and designed interactions that supported fundamental visualisation tasks, specifically: annotation, navigation, filtering, comparison, organization, and sorting. The interactions were evaluated in a user study with 17 participants. We identify the preferred methods of working with the data for each task (e.g. directly tapping rows to hide bars), highlight the strengths and limitations of working with physical data, and discuss the challenges of integrating the proposed interactions together into a larger data exploration system. In general, physical interactions were intuitive, informative, and enjoyable, paving the way for new explorations in physical data visualizations.

“…When moving a slider along the x-axis, the user was able to retrieve the corresponding y-values, which were sonified. Similarly, TIMMs (Manshad, Pontelli, & Manshad, 2012) are objects that provide multimodal feedback and enable blind persons to create and modify graphs and diagrams.…”
