Orientation Detection Based on Wireless Channel Sensing
摘要
Abstract
Human orientation detection is an important branch of human sensing,which have a wide application in many fields such as security,smart housing and somatic games. A new human body orientation detection algorithm WiO was presented:utilize wireless channel information in Wireless Local Area Network to act as the physical quan-tity;we adopt machine learning algorithm to classify the data into the according location,which obtains a relatively good performance of classification;In order to further improve the reliability of detection,we combined the wireless channel amplitude and phase information,and integrate multiple antenna pairs;Meanwhile,we consider the impact of different environmental factors on the experimental results. The experiment shows that our method detects the hu-man orientation effectively,the classification accuracy of four directions in best environment is 98%.关键词
