Research on Activity Recognition Technique of Smart Phone Position and Orientation Independent
摘要
Abstract
The research aims at how to eliminate the influence of smart phone’ s position and orientation variation at human activity recog-nition. Firstly,a method is put forward which recognizes the phone position and human activity followed based on the specific position. The feature is to select the best activity recognition model based on specific position for elimination of influence of mobile position on ac-tivity recognition. Secondly,in order to decrease the impact of mobile phones on the phone toward the sensor data,the absolute value and a simple moving average method is applied to process the sensor data. Finally,to prove the theory,a sensor data collecting tool has been developed in the Android platform,which is used to collect sensor data in different position and orientation of mobile phone,and two ex-periments have been conducted based on the theory and data collected by the tool. The results show that the presented method can effec-tively eliminate the influence of the smart phone’ s position and orientation on the activity recognition,and the activity recognition accura-cy can reach 87. 89%.关键词
