Recently, the range of Internet of things (IoT) technology could be utilized in the real world by the rapid spread of sensor devices. Various sensed information such as temperature, illumination, pressure, and object detection has become a basic point for solving solutions to complex problems that have been difficult to solve by convergence with big data. Particularly, not only the detection of human health and changes in the natural environment but also the rapid development of the analysis and application technology is continuing. As a result, it is expected to dramatically improve the prediction of disaster and quality of life.

In order to implement IoT-based human-care technology for improving the quality of life, we aim to deal with sensor technology and communication technologies as well as big data analytics and its applications. This includes a wide range of application technologies that can be realized in real life as well as theoretical problem solving in relation to the IoT.

In this special issue, the latest research efforts on new theories, technologies, and research are related to IoT and big data technology for smart human-care services and to improve advanced technology. 25 research papers are published in this issue, covering a wide variety of topics including advanced sensor technology for smart human-care services, management issues of social network big data for smart human-care services, data and knowledge mining for smart human-care services, emerging IoT applications and systems for smart human-care services, and IoT solutions for well-being and active ageing. The highlights of these papers are summarized as follows.

Yang et al. examined the smart home service features that current users require and empirically evaluates the relationship between the critical factors and the adoption behavior with 216 samples from Korea. The moderating effect of personal characteristics on behavior is also tested.

The article titled “Real-Time Cloud-Based Health Tracking and Monitoring System in Designed Boundary for Cardiology Patients” by A. Shahzad et al. was made to track and monitor the real-time medical information, bounded in an authorized area, through the modeling of private cloud computing. The private cloud-based environment is designed, for patient health monitoring called the bounded telemonitoring system, to acquire the real-time medical information of patients that resided in the boundary, inside medical wards and outside medical wards, of the medical center.

The article titled “IoT-Based Smart Building Environment Service for Occupants’ Thermal Comfort” by H. Park and S.-B. Rhee presented an Internet of things (IoT) platform for a smart building which provides human-care services for occupants. The individual health profiles of the occupants were acquired by the IoT-based smart building, which uses the accumulated knowledge of the occupants to provide better services. The proposed model was based on the heat balance equation of human body and thermal characteristics of the occupants.

In the article titled “Theory and Application of Audio-Based Assessment of Cough,” Y. Shi et al. introduced some successful cough monitoring equipment and their recognition algorithm in detail. It can be obtained that, firstly, acoustic variability of cough sounds within and between individuals makes it difficult to assess the intensity of coughing.
