'Lines of Play' is a domino art application showcasing recent advancements in augmented reality (AR) technology. Unlike previous mobile AR applications that were limited to horizontal and vertical object placement, these game objects interact with real objects in the player's environment with surface-level resolution. Features of the player's environment provide kinematic constraints (on collision) and serve as obstructions both visually (occlusion) and during gameplay. Using single camera depth information, players can use familiar vector drawing tools to rapidly create and modify lines, rings, paths, and turns of domino tiles. We thereby provide a method for placing a plurality of gaming objects by converting raycasted anchor points into paths of game objects. This opens up novel possibilities of authoring tools specially adapted for AR game development or game-integrated level editing.
