文章设计实现了一种新的人机交互系统,通过视线跟踪技术和物联网技术的结合,实现对家用电器的智能控制。设计了一套头戴式视线跟踪系统,作为物联网的感知层和服务管理层,通过眼睛摄像头采集眼动信息,结合标定信息,实时计算使用者在视野中的注视点,通过场景摄像头实时获取使用者的视野图像。采用Harr特征和Adaboost算法检测识别视野图像中的家用电器。在识别并锁定目标家电的基础上,激活物联网应用层,实现目标家电的控制。本文系统实现了视线注视对三种家电的模拟开关控制,系统具有较高的稳定性。
The article designs and implements a new system of human-computer interaction. Through the combination of line-of-sight tracking technology and internet of things technology, intelligent control of home appliances can be realized. A head-mounted line-of-sight tracking system is designed as the perception layer and service management layer of the Internet of Things. Eye-tracking information is collected through the eye camera. Combined with the calibration information, the gaze point of the user in real time is calculated in real time, and the scene camera is used to obtain real- The user’s view image. The Harr feature and Adaboost algorithm are used to detect the household appliances in the view field image. On the basis of identifying and locking the target appliance, the IoT application layer is activated to achieve the control of the target appliance. This system has realized the sight switch to the three kinds of home appliances analog switch, the system has a higher stability.
