Building blocks: A novel metaphor for solving 3D puzzles

This paper presents our team's design and implementation of an innovative solution to solve the challenge proposed by the 3DUI Contest, which consisted of creating a 3DUI to solve simple 3D puzzles. Rather than using a direct manipulation technique to handle placement of the puzzle pieces, such as the virtual hand, we designed an innovative technique based on build. We aimed to provide a fun and intuitive way to solve puzzles that is not possible in the physical world. Rather than having to focus on specific pieces one at a time, users instead build pieces from individual building blocks, allowing them to focus on the structure of the puzzle space. The results of a user study showed that this system provides a fun and engaging experience for both novices and experts. We believe that performance was determined primarily by experience with games and 3D puzzles rather than by 3DUI design.
