Abstract

Certain example embodiments relate to vending machines with large area transparent touch electrode (LATTE) technology, and/or associated methods. By using the low-E Ag-based coatings described herein, it is possible to create new vending machine user interfaces that are more interesting and interactive than conventional interfaces. Touch-based user interfaces may be useful in vending, attract, and game-playing modes into which example vending machines may be placed and under which they may be operated.
