Abstract
Digital pens are used for character input method without training. Some lecture support systems were developed by using pen input, because of collecting remarks of student in a real time. We proposed a lecture support system by using Wiimote for character input method. Because Wiimote has 3D acceleration sensor, a student writes a character in the air, and our system can recognize a written character. After that the recognized character is displayed on an electronic blackboard. We are using two recognition algorithms by only real-stroke. And we adopt the error correction method by using a tree search algorithm that uses word dictionary. The Japanese characters used in this paper are Hiragana (71 characters), Katakana (71 characters), Kanji (1006 characters taught elementary schools in Japanese) and numerals. The recognition accuracy was 78.9%. Also, the recognition accuracy of phrase was 91.7% by bi-gram model. We confirmed the required performance for utilization.
