Abstract
Polarized light characteristics are detected and mapped to an application, such as product identification. A process of reflecting a directed light emission through a polarizing filter, and sensing the processed light emission having particular characteristics is provided. The characteristics of the sensed light emission is associated with a “color code” that is cross-referenced within a database of color codes.
Claims14
A method comprising:
- determining, by an optical scanner device, a color code based on a light emission having a set of characteristics;
- and
- mapping the color code to a corresponding application including at least one of:
- component parts information instructions, food characteristics, and recycling information.
A computer program product implemented within an optical scanner, the computer program product comprising a computer readable storage medium having stored thereon:
- first program instructions to map a color code based on a light emission to a corresponding application including at least one of:
- product identification, component parts information instructions, food characteristics, and recycling information;
- and
- second program instructions to provide or display information regarding the application to a device via communications hardware.
