本研究旨在設計一套方便盲多重障礙者使用之頭控有聲溝通器；溝通器係利用頭部擺動紅外線感測器來發射訊號，經由89C52 單晶片作拼音、組字和除錯等運算後，透過RS232或USB傳輸介面傳入電腦中，結合語音合成系統來完成發聲溝通。本研究亦使用CCD影像追蹤模組發展自動定位功能，使溝通器可自動追蹤盲多重障礙者頭上之發射器，增加頭控有聲溝通器之準確性。本研究成果可改善無法言語之盲多重障礙者與外界溝通能力，並創造盲多重視障者更優質化的學習和生活環境。 The object of this study is to accomplish the design and manufacture of auto-location head-controlled talking machine for visually impaired people with multiple disabilities. The talking machine makes use of the infrared ray sensors to launch the signal by shaking their heads. The communication functions of Pinyin, associating Chinese character, debugging error are processed based on the single chip processor 89C52. Then the signals are transmitted into a personal computer through the RS232 or USB interface. The pronounced software of head-controlled talking machine is created using TTS system to achieve the communication with other people. This study also develops auto-location function by the CCD tracing module to adjust the infrared ray sensor and increase the accuracy of the head-controlled talking machine. The results of this study can improve the ability of communication for visually impaired people with multiple disabilities, and create the quality assured accessibility environment of learning and living.
