Trends in human activity recognition using smartphones

Transition-Aware Human Activity Recognition Using Smartphones

This work presents the Transition-Aware Human Activity Recognition (TAHAR) system architecture for the recognition of physical activities using smartphones. It targets real-time classification with a collection of inertial sensors while addressing issues regarding the occurrence of transitions between activities and unknown activities to the learning algorithm. We propose two implementations of...

A Public Domain Dataset for Human Activity Recognition using Smartphones

Human-centered computing is an emerging research field that aims to understand human behavior and integrate users and their social context with computer systems. One of the most recent, challenging and appealing applications in this framework consists in sensing human body motion using smartphones to gather context information about people actions. In this context, we describe in this work an A...

Human Activity Detection using Smartphones and Maps

A competitive approach for human activity recognition on smartphones

This paper describes a competitive approach developed for an activity recognition challenge. The competition was defined on a new and publicly available dataset of human activities, recorded with smartphone sensors. This work investigates different feature sets for the activity recognition task of the competition. Moreover, the focus is also on the introduction of a new, confidence-based boosti...

A Study on Human Activity Recognition Using Accelerometer Data from Smartphones

This paper describes how to recognize certain types of human physical activities using acceleration data generated by a user’s cell phone. We propose a recognition system in which a new digital low-pass filter is designed in order to isolate the component of gravity acceleration from that of body acceleration in the raw data. The system was trained and tested in an experiment with multiple huma...
