Abstract

The research conducted through community service aims to develop artificial intelligence (AI)-based software capable of detecting students' emotions at SMKS Methodist 8 in real time, as an effort to support teachers in implementing a more adaptive and responsive learning approach. This system is designed by integrating facial recognition and emotional expression analysis through a camera, which is then processed using the Certainty Factor method to determine the confidence level of the detected emotional classification. This approach allows the system to generate emotional diagnoses with a reliable degree of confidence, based on predefined parameters. Test results have shown that the software is capable of detecting several basic emotions such as happiness, sadness, anger, and neutrality with an adequate level of accuracy. The implementation of this system in classrooms is expected to assist teachers in quickly identifying students’ emotional states, allowing learning strategies to be adjusted accordingly to improve the effectiveness of the learning process. Therefore, this technology offers an innovative solution in supporting the improvement of education quality through an approach that focuses on individual students.

Abstract

Human emotion detection and heart rate estimation are two important aspects in developing a more responsive and adaptive human-computer interaction system. This study proposes a real-time video-based system that is able to detect facial emotions and estimate the user's heart rate simultaneously. The Convolutional Neural Network (CNN) method is used to classify facial expressions into several emotion categories such as happy, sad, angry, afraid, and neutral. Meanwhile, heart rate estimation is carried out using a non-contact Photoplethysmography (PPG) approach, which utilizes variations in color intensity in the user's facial area from video recordings to calculate the pulse rate. This system is developed using a standard webcam camera without additional medical devices, allowing for practical and economical implementation. The test results show that the system is able to recognize facial expressions with good accuracy, and estimate heart rate with an average error rate that is still within the tolerance limit of non-medical applications. By integrating computer vision technology and biometric signals, this study contributes to the development of a passive, real-time, and easily accessible emotion and health monitoring system.

Abstract

The difficulty in understanding individual characteristics based on palm lines is still an attraction in the context of education and technology-based experiments. This study aims to develop an educational application that is able to detect palm lines using a laptop camera, then predict certain characters or conditions based on the input. This system is built using the Certainty Factor (CF) method to provide certainty-based inferences on the visual symptoms of the detected palm lines. The process begins with taking a picture of the hand directly through the camera, followed by detection of main lines such as the life line, head line, and heart line using simple image processing techniques. After that, the system will display symptom-based questions related to the shape of the visible palm lines, then calculate the certainty value of the inference results using CF. This application is non-commercial and was developed as an educational tool to introduce the basic concepts of expert systems and Python-based visual processing. The system has successfully detected major palm lines with an accuracy of 80% under standard lighting conditions, and produced predictive results with certainty values that matched expected outcomes in over 70% of test cases. This demonstrates the potential of the CF method in processing visual data for educational inference. The system functions reliably as an educational tool, successfully demonstrating how certainty-based logic can be applied to simple visual data, and has been well-received in testing scenarios for learning purposes.
