本文提出一個有CMOS鏡頭及影像處理功能並可以播放語音之多功能學習平台。其主要功能為，在佈滿QR Code之書本上讀取QR Code後再播放其對應之語音，可以協助視覺障礙者邊點字邊學習正確發音，此功能讓視覺障礙者能更輕鬆的學習。 一般視覺障礙者之主要學習方式是透過點字方式學習。點字學習之優點為可以藉由觸摸的方式作辨識字型，及對已學會的點字字型可以獨立做辨識。點字學習或辨識之缺點為學習時必須經由第三者輔助，才能得知摸到的字型為何。若文章文字過多，視障者不便辨識。 多功能學習平台可以改善視障者在學習時，必須有旁人在旁做讀音協助之缺點，且視障者若欲在短時間內辨識較長之文章，多功能學習筆可做較有效率之輔助，讓視障者的生活更增添許多輔助的方式。 一共分為四個階段，QR Code之編碼、影像擷取、影像處理和解碼，即可實現視覺障礙輔助之多功能學習平台。其使用方式為利用CMOS鏡頭(Webcam)，對佈滿QR Code Pattern之紙張(書籍)，做讀取及解碼之動作，利用多功能學習平台之語音功能，將所得之資訊播放出來，即可讓視覺障礙者明確的聽到語音之內容。 This thesis presents a Multi-function Learning Platform for Visual Disabilities which has Image-Processing and voice function with a CMOS sensor. The main capability is reading the QR Code (2D barcode) and playing the corresponding voice on a book which covered with QR Code. It also can to assist Dysopia person brailling by the voice. They will easier to learn it.
In general, a main learning method of Dysopia person is Braille. A strong point of Braille can recognize the style of calligraphy by touch, and can be independent recognizing for the words which already learning. A defect of Braille is needed an observer telling them what words they touched at learning. If there are too many words, they will hard to learn it.
Multi-function Learning Platform can to improve the defect. If Dysopia person expect to recognize many words in a few times, it can assist more effective.
To achieve a Multi-function Learning Platform for Visual Disabilities is divided into four parts QR Code Encoding, Image Catching, Image Processing and Decoding. We will use a webcam to take QR Code pattern on a book with processing and decoding. Using the voice function broadcasts the contents for Dysopia person that they can get the right information by the voice.
