Today, interactive tables that are based on IR technologies (frame or lasers) are the most popular solution. They perform reasonably well but it’s impractical to use them in a restaurant setting for several reasons. The table frame protrude from the top of the table surface along the entire perimeter, giving a “bulky” feel to the table and making guests feel uncomfortable. The frame would also increase the risk of spilled drinks. Spillage can easily result in hardware damage.
