Abstract

An embedded interaction code-enabled display includes: an outer transparency layer, an optional inner transparency layer, an optional infrared-reflection layer between the outer transparency layer and the inner transparency layer, an EIC dot pattern between the outer transparency layer and the infrared-reflection layer, and, optionally, transparency glue between the outer transparency layer and the infrared-reflection layer or the inner transparency layer. The outer transparency layer 1308 and the inner transparency layer may be glass, plastic, or a film. The EIC dot pattern may be printed on, or pressed onto, the inner side of the outer transparency layer. The EIC dot pattern may include an encoded surface identifier that identifies the embedded interaction code-enabled display. The encoded surface identifier may uniquely identify the embedded interaction code-enabled display.
