Team Status Report 04/12

This week, our team made progress on multiple fronts despite facing some initial setbacks. We successfully developed a 9×9 capacitive touch grid with an extended border to improve wiring separation and structural rigidity. Though we tested 1/16-inch acrylic as a top layer, it required too much pressure for consistent readings, so we plan to revert to a thinner material. Unfortunately, one MPR121 IC was shorted during testing, and we’re waiting for replacements. On the software side, we implemented an enhanced hint system that highlights existing numbers in the selected cell’s row, column, and 3×3 grid, added footnote functionality for tracking potential candidates, and created real-time explanations of hint logic in the terminal. We also developed a side UI panel with placeholder sections that will improve the user experience and fits within projection width constraints. Moving forward, we plan to rebuild the touch grid, expand the UI with a zoomed-in cell view, add on-screen explanations for Sudoku constraints, create an introductory guide, and determine how to implement different functionalities in the side panel.
