This week, our team made a few major changes to our design – a major one is that we decided to remove the use of OpenCV and a camera for Sudoku board detection. Instead of relying on image processing, we will now load the Sudoku board file directly, simplifying our system and reducing unnecessary complexity.
In addition, we have improved the interaction method. Rather than using arrow keys to navigate through 81 cells – which could be tedious – we decided to implement a capacitive touch sensor grid. This involves laying copper foil and dielectric materials to create 81 capacitors, allowing users to interact naturally by selecting cells through touch. The projected Sudoku board will align with this grid to create a real-time interactive experience, where users can select a cell, enter a value, and seamlessly move to another.
Additionally, we had a team meeting on Friday to finalize the project’s direction and establish a more robust and reasonable set of key testing metrics – for example, we decided that the projection system should maintain an accuracy of within 1mm. To ensure that our project timeline reflects the changes we made to our design, we are also in the process of updating our Gantt chart. In terms of parts – we have ordered the Raspberry Pi that will serve as the core processing unit for our design.
Moving forward, our focus will be on implementing the capacitive touch grid system and integrating it with the Raspberry Pi. We will also continue refining the projection system to optimize accuracy and responsiveness. Our software development plan will be adjusted to align with these design modifications, and we will begin testing the board interaction mechanics before moving into full system integration.
