Problem
Addressing the challenges faced by both visually impaired and sighted chess enthusiasts, our project aims to create a universally accessible chess platform. Locating opponents of similar skill levels for over-the-board games poses a common hurdle for players, limiting the availability of challenging matches. Additionally, digital platforms bring their own set of issues, including difficulties in maintaining focus and an aggressive playstyle during online chess games. These challenges impact the overall quality of the digital chess experience. Our goal is to overcome these obstacles, providing an inclusive and enjoyable chess environment that caters to the diverse needs of players, whether they prefer traditional over-the-board play or digital platforms.
Solution
To address the challenges faced by chess enthusiasts, both visually impaired and sighted, we have developed an innovative solution that seamlessly integrates a physical chess board with a mobile app. This unique combination allows players to choose opponents from our community or engage in games with friends and even international counterparts, all while enjoying the authentic experience of playing with a physical board. By merging the tangible and digital aspects of chess, our solution enhances the gaming experience, providing real moves and real-time interactions. This approach not only caters to the diverse preferences of players but also fosters a sense of connection and engagement within the chess community.
The Future is Here
Welcome to the future of innovation, where a project is leading the charge with groundbreaking solutions that defy expectations. Our journey is fueled by passion, creativity, and a relentless pursuit of excellence. At Smart Chess, we don't just dream of the future; we create it. Our commitment to innovation knows no bounds, and our results speak for themselves.

How to optimize the location of the electromagnet for fast responses ?
We used BFS to find the shortest path between the current position of the piece and the target position. Then we used the shortest path to find the optimal location for the electromagnet.
