| Summary: | 碩士 === 國立臺灣師範大學 === 圖文傳播學系 === 102 === Augmented Reality (AR) marker helps pattern recognition and generates virtual objects, but it always be presented by a black square and hinders the aesthetics of overall design. The objective of this proposal is to integrate AR and the image-switching function of dot matrix hologram, which makes the marker invisible under a meaningful cover image from the normal observation angle. The AR marker can be detected from a specific angle. To design the dot matrix hologram, color index image and grayscale image are used to output the grating spots with different pitches and orientations on the photoresist, which lets the dot matrix hologram possesses the image switching function. In addition, this research makes compare between hologram’s marker and visual marker, to analyze in which the condition can be satisfied to bring out the AR virtual object when camera detects from the different angle or different distance. The result shows the AR effect can be triggered successfully by using the dot matrix hologram, and, the same hologram also brings the distinct virtual object when image-switching effect is in implementation. Besides, this research compares the traditional AR marker and the holographic AR marker in different angles and distances of camera, to detect the conditions which AR effect can be correctly presented. Eventually, the data of questionnaire indicates that most of the users prefer the holographic AR marker. This research combines dot matrix hologram and AR, which is the world’s first and has many potential applications in the future.
