Abstract

Recent advances in Internet of Things (IoT) technologies and the reduction in the cost of sensors have encouraged the development of smart environments, such as smart homes. Smart homes can offer home assistance services to improve the quality of life, autonomy, and health of their residents, especially for the elderly and dependent. To provide such services, a smart home must be able to understand the daily activities of its residents. Techniques for recognizing human activity in smart homes are advancing daily. However, new challenges are emerging every day. In this paper, we present recent algorithms, works, challenges, and taxonomy of the field of human activity recognition in a smart home through ambient sensors. Moreover, since activity recognition in smart homes is a young field, we raise specific problems, as well as missing and needed contributions. However, we also propose directions, research opportunities, and solutions to accelerate advances in this field.

Highlights

With an aging population, providing automated services to enable people to live as independently and healthily as possible in their own homes has opened up a new field of economics [1]
A minority class is harder to predict because there are few examples of this class, by definition
We have highlighted the challenges of Human Activity Recognition in smart homes, some of which have particularities compared to other fields of HAR

Summary

Introduction

With an aging population, providing automated services to enable people to live as independently and healthily as possible in their own homes has opened up a new field of economics [1]. A smart home is a house equipped with many sensors and actuators that can detect the opening of doors, the luminosity of the rooms, their temperature and humidity, etc. It is possible to find in the houses, televisions, refrigerators, and washing machines known as intelligent, which contain sensors and are controllable remotely. All these devices, sensors, actuators, and objects can be interconnected through communication protocols
