The Tactile Matrix, or Tangible Interactive Matrix is a system for an illuminated, machine-readable matrix of objects that performs real-time computation and dynamic projection-mapping. The Tactile Matrix is applied to many research projects to make complex systems intuitive and approachable for a more broad range of stakeholders.

Illuminated, tangible-interactive matrices have immediate applications as collaborative computation tools for users who want to leverage matrix-based mathematical modeling techniques within a friendly and accessible environment. The system is designed as an open source kit of both off-the-shelf items (such as Lego) and components that are inexpensively fabricated with standard equipment (such as laser cutters).

The Tactile Matrix is designed to (a) make matrix-based mathematical methods more accessible and intuitive to users who otherwise do not have access to such tools and/or (b) provide an interactive narrative and story-telling device for experts who wish to present or explain matrix-based concepts to non-experts.
