碩士 === 國立臺灣師範大學 === 圖文傳播學系 === 97 === The objective of this research is to develop two hologram-based real-time interactive systems. One system is based on the “image switch” visual effect with the diffractive light from a dot matrix hologram. The participants can interact with audio through two light sources in different incident directions in turns to make the dot matrix hologram displays “image switch” in different colors. The other one is based on the “flow dynamic” visual effect with the diffractive light from a dot matrix hologram. These two systems synthesize audio with different pitches and tempos in accordance with the diffractive light from a dot matrix hologram. As the single light source projects on the dot matrix hologram in different angles, the hologram will display dynamic flow with the lighting orientates. The other system will synthesize audio in different tempos according to the position of the lighting. The two real-time interactive systems have great potential to be new musical expression interfaces. The research has successfully integrated with the fundamental theories of different sciences and technologies, such as optics、digital image processing、musical performance and digital signal processing.
