Let’s take a step back and focus on the real challenge behind your question. It’s not just whether a capacitive touch matrix on a whiteboard is possible — the answer is yes — but rather identifying the bottlenecks and how feasible the project is. The first challenge is capturing user input accurately and converting handwriting or touches into digital text. The next is integrating an automatic calculator that can process that input in real time, which requires reliable software to interpret and act on the data.
Once these challenges are understood, the important questions become how long it would take to solve them and whether the project is worth pursuing. Breaking it down this way shows how to approach complex technical problems: identify the key hurdles, understand what tools already exist, and evaluate feasibility before moving forward.
