DHAR: Design and Implementation of a New Distributed Human Activity Recognition System

초록

Recently, cloud computing technology has been rapidly growing faster, offering cloud-based human activity recognition applications with lower latency. In this paper, we design and implement a new distributed driver activity recognition system (DHAR). The proposed distributed system absorbs a more significant number of input sensor data from humans with a lightweight model that provides high accuracy for driver activity recognition. In addition, our model has employed the entire convolution network ? Long Short-term Memory (FCN-LSTM) to predict human activities of a total of 6 classes such as walking, walking upstairs, walking-downstairs, sitting, standing, and laying. We evaluate the proposed system using a well-known UCI-HAR opensource dataset containing a collection of smart-phones data for 30-subjects while performing various activities using a smartphone. We used various Amazon cloud computing services for the deployment of the proposed architecture. The experimental results show that the proposed architecture improves end-to-end latency by 2.7 times compared to the traditional architecture.
