🧩 VRQA-Bench

Paper Code

A multiple-choice visual reasoning benchmark built on πŸŒ€ maze navigation and πŸ“¦ Sokoban puzzles. Each sample provides an initial-state image, an optimal-solution video, and a question about the planned trajectory.

🏷️ Categories

Category Task Description
C1_turn_count πŸŒ€ maze Total number of direction changes along the path
C2_turn_direction πŸŒ€ maze Number of LEFT / RIGHT turns
C4_sokoban_push πŸ“¦ sokoban Direction of a specific push
C5_direction_count πŸŒ€ maze Number of steps in a given direction
C6_push_dir_count πŸ“¦ sokoban Number of pushes in a given direction

πŸ“ Annotation Fields

question, options (A–D), answer (correct key), correct_value, task_type, input_image / video_path (relative to each split dir), _solution (ground-truth solution trace).
