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.
Claims10
A three-dimensional puzzle comprising:
- a shell having at least four faces and formed by multiple shell segments, at least some of the shell segments being movable relative to adjacent shell segments;
- a core within the shell, the at least some of the shell segments being repositionable relative to the core, and the faces being freely to rotatable relative to the core about axes extending from the core toward the faces;
- a plurality of unique signatures, each located at one of the at least some of the shell segments;
- system electronics at the core;
- and
- at least one optical sensor, each optical sensor configured to capture an image of multiple shell segments to enable the system electronics to detect an identity and orientation of multiple shell segments based on the unique signatures.
