摘要
为了摆脱传统交互方式的局限性,指出了用人的指示行为作为人机交互输入方式所带来的直观性和方便性。在指示行为的视觉识别过程中,手指的空间位置检测是极为关键的。为了识别人的指示行为,重点从人手的视觉检测方法、手指和指尖的空间定位两个方面系统地阐述了手指空间位置检测技术,对各种方法的适用性及其优缺点进行了分析与归纳,并说明了基于视觉的手指空间位置检测的一般过程,探讨了指示行为在人机交互中的应用现状及前景。
In order to break the limitations of traditional mode of interaction,the intuitive and convenient character of employing people’s pointing gesture as an human machine interaction(HMI)input device is pointed out.However,vision-based finger spatial location detecting is a key part in pointing gesture recognition.To recognize people’s pointing gesture,focusing on hand detecting and finger and fingertip spatial locating,vision-based finger spatial location detecting is systematically described,and the applicability of various methods and there strengths and weaknesses are analyzed and summarized,the general process of vision-based finger spatial location detecting is also presented.Finally,the application condition of people’s pointing gesture in HMI is also discussed.
