中文摘要 | 本論文將針對肌肉萎縮症或漸凍症等肢體障礙患者,無法使用滑鼠及鍵盤但頭部可正常擺動之人士,提供一種使用電腦的控制及輸入介面。透過電腦及Webcam設備,拍攝使用者頭部範圍之影像,並依據使用者頭部之擺動方向及距離,經由影像處理的計算轉換為對滑鼠游標位置的控制及執行點擊滑鼠按鍵之動作。在判斷殘障者頭部擺動的部分,須先定義出特徵點並自影像中加以辨識。而每個人的頭部輪廓、五官位置、五官形狀、髮型、膚色、疤痕等等因素,均有不小的差異及變數,若要定義出一規則,自不同的人之臉部影像中辨識出特徵點,並準確的控制滑鼠游標,在程式方面的運算時間及複雜度將大幅增加。為了準確且快速的辨識出特徵點,本論文使用直徑約1公分之圓型貼紙作為識別標籤,黏貼於使用者額頭上。經由網路攝影機(Webcam)取得影像後,辨識出識別標籤的位置並移動滑鼠游標。本論文透過Window API,依據滑鼠游標一連串之移動方式,判斷出使用者欲點擊滑鼠按鍵之意圖並執行該動作,提供肢體障礙患者一種新的輔助方案,藉由頭部的擺動實現電腦操作之功能。 |
英文摘要 | This essay is aimed at people who suffer from MD (muscular dystrophy) or ALS (amyotrophic lateral sclerosis). They can't use mice and keyboards, but they can move their heads. We can offer them a kind of interface controlled by computers. By the equipment of the computer and Webcam, we shoot the wiggle directions and distances of the users' head, via image process, to calculate and transform the position controlled by the mouse cursor and do the action clicked by the mouse. To determine the head swings from the handicapped, we should define and recognize the traits from the image. The outline of the head, positions of the facial features, hair styles, skin tones, and scars and so on are different dramatically. If we want to define a rule from the features of different face image and accurately control the mouse cursor, the time and complex of the program will increase a lot. For recognizing the features accurately and quickly, we use a round stick (diameter 1 cm) as an identification label stuck on the forehead of the user. By the image from the Webcam, we can recognize the positions of the label and move the mouse cursor. In the essay, we define a set of rule according to a series of move ways from the mouse cursor to determine the user's intention and perform the action. By making the use of Windows API auto developing program system, we have offered the handicapped a new assistant scheme that can help them use the computer only by their swings of the heads. |
