Facial features are critical visual indicators for understanding what a person is experiencing, providing valuable insights into their emotions and physical states. However, accurately detecting these features under diverse conditions remains a significant challenge, especially in computationally constrained environments. This paper presents a facial feature extraction method designed to identify regions of interest for detecting facial cues, with a focus on improving the accuracy of eye and mouth detection. Addressing the limitations of standard Haar cascade classifiers, particularly in challenging scenarios such as droopy eyes, red eyes, and droopy mouths, this method introduces a correction algorithm rooted in normal human facial anatomy, emphasizing symmetry and consistent feature placement. By integrating this correction algorithm with a feature-based refinement process, the proposed approach enhances detection accuracy from 67.22% to 96.11%. Through this method, the accurate detection of facial features like the eyes and mouth is significantly improved, offering a lightweight and efficient solution for real-time applications while maintaining computational efficiency.

This paper presents a device that can detect the deficiency of Glucose-6-Phosphate Dehydrogenase in blood samples. A color sensor system was used in which the blue value of a sample is observed under ultraviolet light. A deficient blood sample will yield values from 19 and below, while a normal blood sample will yield values from 25 and above. To consider values outside the specified range, values of 20 and below are considered deficient, and values above are considered normal. The system made use of a myRIO microcontroller intended as an improvement to the PIC microcontroller. The system also made use of a light switching mechanism that uses the white color of the base to determine if a sample is inserted and switches between the ultraviolet and white light as a way of minimizing power consumption.

KamAI is an Android-based mobile application designed to support the learning and recognition of basic Filipino Sign Language (FSL), the official sign language of the Deaf community in the Philippines. The system integrates Convolutional Neural Networks (CNNs) and Google MediaPipe to enable real-time gesture recognition for FSL letters, numbers, and common words. To evaluate the application’s overall quality and practical usability, User Acceptance Testing (UAT) was conducted using the ISO/IEC 25010 software quality framework. Six quality attributes, Functionality, Reliability, Compatibility, Usability, Efficiency, and Portability, were assessed using a five-point Likert scale. Results showed that all evaluated attributes received “Highly Acceptable” ratings, with mean scores ranging from 4.50 to 4.77. Functionality (4.73) and Portability (4.77) received the highest ratings, indicating accurate recognition performance and effective operation across various Android devices. These findings demonstrate strong user approval and confirm KamAI’s readiness for real-world deployment as a mobile assistive learning tool that promotes inclusive education and digital accessibility in the Philippine context.
