A Specification Method of Character String Region in Augmented Reality

This paper proposes a method to enter characters and/or character string in an augmented reality using a gesture motion. The proposed method detects the region of character string using the gesture motion. It consists of five phases; template generation, skin color detection, hand region detection, gesture motion extraction and designation of character string region. The template image consists of two fingers because a gesture is to take hold the tips of the first and second fingers. In the skin color detection, we extract the skin color on the basis of values in saturation by using threshold processing. The hand region is detected by calculating areas and detecting the area with the maximum value as a hand. The gesture motion is extracted using template matching. In order to show the effectiveness of the proposed method, we conduct experiments for character string specification.
