Special Issue Information

Dear Colleagues,

Emotion recognition is an ad hoc research subject in various fields that apply human emotional reactions as a signal for marketing, automation, entertainment, technical equipment, and human–robot interaction. Sensors are used to detect human emotions and are associated with many developments. The recognition and evaluation of emotions are complex subjects due to their interdisciplinary nature. However, sensors support much information for these recognitions and evaluations. Many scientific disciplines, including psychology, medical sciences, data analysis, and mechatronics, are involved in the research into sensor applications for emotion recognition.

This Special Issue aims to bring together researchers and practitioners working on the design, development, and evaluation of sensor-based emotion recognition systems. The objective of this Special Issue is to provide a comprehensive view of the latest research and advancements in the field of sensors applications on emotion recognition. This Special Issue provides a framework to discuss and study sensor applications from the perspective of emotion recognition. We invite researchers to contribute to this Special Issue by submitting comprehensive reviews, case studies, and research articles in the field of theoretical and methodological interdisciplinary sensors applications on emotion recognition. In particular, sensor application technologies specifically devised, adapted, or tailored to address problems in emotion recognition are welcome.

Brain–computer interfaces (BCIs) allow information to be transmitted directly from the human brain to a computer, enhancing the ability of human brain activity to interact with the environment. In particular, BCI-based control systems are highly desirable because they can control equipment used by people with disabilities, such as wheelchairs and prosthetic legs. BCIs make use of electroencephalograms (EEGs) to decode the human brain’s status. This paper presents an EEG-based facial gesture recognition method based on a self-organizing map (SOM). The proposed facial gesture recognition uses α, β, and θ power bands of the EEG signals as the features of the gesture. The SOM-Hebb classifier is utilized to classify the feature vectors. We utilized the proposed method to develop an online facial gesture recognition system. The facial gestures were defined by combining facial movements that are easy to detect in EEG signals. The recognition accuracy of the system was examined through experiments. The recognition accuracy of the system ranged from 76.90% to 97.57% depending on the number of gestures recognized. The lowest accuracy (76.90%) occurred when recognizing seven gestures, though this is still quite accurate when compared to other EEG-based recognition systems. The implemented online recognition system was developed using MATLAB, and the system took 5.7 s to complete the recognition flow. Full article

Frontal and axial knee motion can affect the accuracy of the knee extension/flexion motion measurement using a wearable goniometer. The purpose of this study was to test the hypothesis that calibrating the goniometer on an individual’s body would reduce errors in knee flexion angle during gait, compared to bench calibration. Ten young adults (23.2 ± 1.3 years) were enrolled. Knee flexion angles during gait were simultaneously assessed using a wearable goniometer sensor and an optical three-dimensional motion analysis system, and the absolute error (AE) between the two methods was calculated. The mean AE across a gait cycle was 2.4° (0.5°) for the on-body calibration, and the AE was acceptable (<5°) throughout a gait cycle (range: 1.5–3.8°). The mean AE for the on-bench calibration was 4.9° (3.4°) (range: 1.9–13.6°). Statistical parametric mapping (SPM) analysis revealed that the AE of the on-body calibration was significantly smaller than that of the on-bench calibration during 67–82% of the gait cycle. The results indicated that the on-body calibration of a goniometer sensor had acceptable and better validity compared to the on-bench calibration, especially for the swing phase of gait. Full article
