音樂在人們的生活已是不可或缺的一項要素,不僅能調適心情、安撫情緒,對精神上的治療也有一定的成效。過去的研究證實音樂能有效地刺激失智症者腦神經,達到減緩症狀的效果。 本研究結合電腦與鐵琴開發一套互動式音樂輔具。硬體部份,我們利用Arduino微控器與全彩LED燈條,設計一套互動式鐵琴演奏系統,並使用電腦作為編輯曲目及硬體控制之平台。實際演奏使用時,電腦會將音樂的節拍與音階訊息,透過UART傳輸方式傳送至鐵琴演奏系統。此系統將音樂中所對應的琴鍵敲擊位置和節拍,以LED燈條顏色及跑馬燈方式,提示使用者進行節拍與音階的敲擊訓練,此外在電腦端也開發了樂曲編輯模式,讓使用者進行音樂的編輯及儲存。經過數次現場實測和實際試用後,我們驗證此論文中所設計的互動式鐵琴演奏系統,除了有效地提升使用者在音樂上的學習動機,更能利用此系統的編輯曲目功能,讓使用者藉由熟悉旋律及敲擊本系統的樂趣,不斷重覆地練習,有效地刺激失智症者的大腦,達到減緩失智症狀效果。
Nowadays, music is indispensable in our life. It not only placates our moods and sentiments, but also has good effects upon the mental sickness. There are several researches indicate that the music stimulates efficaciously the cranial nerve, to ease the symptoms off of the Dementia patient. In this theme, we develop a interactive musical assistive devices with the computer and glockenspiel. The play system is made up of Arduino an LED light, and connects with the computer to edits the melodies. When it starts, the rhythms and musical scales will be sent by UART. The LED shows the rhythms and hitting position of the song, instructs the user to play. Besides, the user can put their favorite songs into this system by melody edit mode. After test, this research investigates how interactive musical assistive devices may helps the Dementia patients to stimulate their brain.
