Blind chess

A feature on this online website is "blind set pieces".. I think this an interesting feature.. but in real life I thikn you would know where ur own pieces are because you could feel your own pieces on the board with your hands and recognize each one. (or an option for that).. ADDITIONALLY.. knowing your opponents last move via PNG but only showing his last move.. like  Be4 and then upon another move erasing that text, only showing the last move. When you're looking at the board it becomes impossible to keep track of what was where and what piece moved where. You would have to be a genius.. especially for both sides simultaneously. If you saw your own pieces and and the PNG for only the last opponent move it'd be possible, becuase you would get a feel for each piece on your opponents size as the game went along.
