基于手势识别的智能输入

摘要

In the human-computer interaction, the keyboard far cannot satisfy the requirement of people. In this paper, a method based on gesture recognition algorithm is proposed, and combine with keyboard keys to realize intelligent input. In the algorithm, the hand region is extracted by using skin color segmentation. According to the hand shape to detect the thumb and the number of outstretched fingers, and their position, then gestures are converted into binary language computer can accept. Combined binary number with the keyboard keys, gestures are defined as the different buttons to achieve compute intelligent input. The experimental results show that the algorithm has certain robustness, and it can achieve a high success rate.%针对在人机交互中键盘远远不能满足人们的要求，提出了一种手势识别算法，并结合键盘的按键实现智能输入。该算法采用肤色分割提取出手部区域，根据手形检测出大拇指和伸出的手指数目及位置，把手势转化为计算机所能接受的二进制语言。根据二进制数，结合键盘的按键，把不同手势定义为不同的按键，实现对计算机的智能输入。实验结果表明该算法具有一定的鲁棒性，并能达到较高的成功率。
