Abstract
This thesis presents two tangible user interfaces for interacting with portable physical constraints. The first system, GaussMarbles, a system of spherical magnetic tangibles. Unlike previous design of magnetic tangibles, the proposed magnetic polyhedron design support 3D interactions. When the ball is rolling, the shape of magnetic fields provides robust features for the analog Hall-sensor grid to track the near-surface 3D position in real-time. We also propose a simple procedure to fabricate the proposed magnetic sphere with ease. Several applications are demonstrated to show possible interactions between the GaussMarbles and physical constraints in various levels of embodiment. To achieve rich-ID an high-DOF, we present the second system, GaussRFID, a magnetic-RFID development kit for embedding interactivity by creating physical artifacts. The hybrid RFID and Magnetic-field tag sensing consists of two major components: GaussTag, a magnetic-RFID tag combined with a magnetic unit and a RFID tag, and GaussStage, the tag reader as well as a TUI design platform combined with an analog Hall-sensor grid and an RFID reader. A GaussStage reads the ID, 3D position, and partial 3D orientation information of a GaussTag nearby the sensing platform, and provides simple interfaces for users to incorporate different types of physical constraints, making display and actuator modules in a plug-and-play fashion. The two proposed approaches explore the token+constraint interfaces on the portable platform and complete a toolkit for designers and researchers to create various tangible interactions with physical constraints.
