I am a coach at a small high school. We are starting a chess club. We have Epson BrightLink projectors with the interactive boards. Is there a way we can have a chess board displayed on the whiteboard that allows a finger to move pieces while also using a pen to annotate? An example can be seen here.
Try using the chessboard on https://szachydzieciom.pl/?page_id=61146 in full screen mode (click the full screen icon). I know that in some schools in Poland it works well with touch whiteboards. But dragging pieces may not work. Instead you should tap the piece to move and then disconnect your hand and tap the target square separately.
