Abstract: Disclosed herein are embodiments of three-dimensional puzzles that implement image sensors to read signatures of individual shell segments to thereby determine shell segment patterns. Also disclosed are embodiments of systems that implement RGB sensors adjacent gradient color maps to provide contactless absolute position encoders.
Abstract: Embodiments disclosed herein include methods and apparatus for tracking three-dimensional puzzle components using embedded signature and rotation sensors. A system of unique signatures enable the identification of the components by internal sensors and rotation sensors enable tracking the components as the move around on the puzzle surface. The system fosters greater enjoyment of the puzzles by offering interactive feedback and guidance. Competitions are also facilitated.
