碩士 === 銘傳大學 === 電子工程學系碩士班 === 99 === The Altera DE2-70 Multimedia platform created by Terasic is used by this research to design a virtual-touched control music player. The aim is to let the user can easily control the music playing without wearing any devices. At first, the digital camera is used to capture the image and the hand area is decided by skin detection. Then image processing techniques are adopted to filter out the noise and fingertip detection is utilized to decide the touched music player function. The captured image is displayed on the touch panel and the functions can be chosen by the user are play, previous song, next song, volume up, volume down, and stop. To fulfill the requirement of real-time image processing, Verilog language is used to write the control programs and implement the design by hardware. The achieved research results can be applied to other products of consumer electronics where the virtual-touched control is required.
