This document proposes a framework for dynamically physicalizing data. It describes the Tangible Hologram (TangHo) platform, which uses a 6 degree of freedom robotic arm prototype built from Lego Mindstorms. The arm can interact bidirectionally with a user through holograms displayed via HoloLens. Challenges include inverse kinematics since the final system will be body mounted. The document concludes that the conceptual framework and TangHo prototype allow for data-driven physicalization of large multi-dimensional datasets through dynamic and interactive designs.

TangHo Prototype
 Lego Mindstorms-based
6DOF arm prototype
 motors can be locked or set to
float mode
- useful for bidirectional I/O
 Replaceable end effector for different
types of non-visual feedback
 Challenges
 inverse kinematics (final system
is body mounted)
- use robotics toolbox (MATLAB)
 limited HoloLens hand tracking
 3D printing of final arm
