Abstract
A system of optical sensors determines whether an object is placed on the system by passing light through the sensor layer, detecting light reflected from the object above the sensor layer, and identifying the object based on whether a color detected in the light corresponds to a color of the side of the object that is positioned on the system over the sensor layer. When the system includes multiple optical sensor units, the system may determine where the object has been placed by determining which of the sensor units detect light reflected from the side of the object.
