User-Created Marker Based on Character Recognition for Intuitive Augmented Reality Interaction

Abstract

This paper proposes a novel concept of markers with alphabet combinations for Augmented Reality (AR) applications. Compared to traditional markers with square patterns, the proposed markers composed of alphabets have several advantages for interaction. The proposed markers are based on English alphabet letters, allowing users to interact intuitively by combining the alphabetized markers to from words. The marker recognition system operates at a robust 58.8 fps, recognizing the markers in a fast and effective method. In this paper, we verify the effectiveness of the proposed markers by implementing an AR application.
