Abstract

Sudoku is one of the most popular puzzles of all time: easy to understand but still very challenging, Sudoku continues to captivate players all over the world through newspapers, puzzle books, and digital devices. The application introduced in this work is a multilingual, sketch-based version of the Sudoku game. Sketch input renders more flexibility to users and increases usability. Multilingual support paired with sketching allows the game to serve as an educational tool for those learning a new language, with the current implementation supporting Chinese and Hindi. The recognition algorithm proposed in this work, based on the Hausdorff metric, easily enables extending the application to support other languages. Preliminary results indicate an overall accuracy of over 93% when recognizing Chinese and Hindi numbers at the same time.
