摘要: 近年來,隨著手勢辨識研究的演進,許多利用體感操控之應用也逐漸發展,使得人們只需站在攝影機前便可操控電腦。有鑑於在會議室中之投影片演示時,演示者無法適時地站在投影布幕前利用雙手指示重點,而只能侷限於在電腦前演示投影片。
本研究藉由微軟推出的Kinect,應用手勢辨識於控制PowerPoint演示。本論文透過擷取人體參考點,辨識雙手相對於人體之單一方向動作,希望達成包含能夠讓使用者順暢切換頁面、在一定程度上的展示圖片功能及簡單的畫面指示效果功能之投影片控制輔助系統。
本論文之貢獻有兩點:第一,本論文提出一手勢辨識系統,在不同體型及臂展之成年使用者間,皆能達到一定程度之辨識效果。第二,本論文之系統整合圖片展示功能及畫面重點指示於投影片系統中,讓使用者能夠容易將投影片中之內容演示。
Recently, as the evolution of the researches on hand gesture recognition, many somatosensory control applications are gradually developed, and so that people can stand in front of the camera to control the computer. In view of the slide presentation in the conference meeting room, the presenter is limited in front of the computer, and couldn’t use their hands to point out the emphasis on the projection screen in time.
This thesis describes a gesture recognition system which is used to control a PowerPoint presentation by the Microsoft Kinect. This system focuses on the hand gesture recognition by extracting the human body reference points and recognizing the gestures which the hand movements are one direction related to human body, and then make the users to navigate the slides as fluid as possible, to resize an image on a slide and to display a pointer on slides which they want to mark to the audience.
The following are the contributions in this thesis. First, we proposed a gesture recognition system, which can achieve a limited extent recognition effect on adults. Second, it integrates an image-showing function and a pointer function in the system, making presenter easily show the key point they want to display on a slide.
