Abstract

Human gaze is a promising input modality for being able to be used as natural user interface in touchless technology during Covid-19 pandemic. Spontaneous gaze interaction is required to allow participants to directly interact with an application without any prior eye tracking calibration. Smooth pursuit eye movement is commonly used in this kind of spontaneous gaze-based interaction. Many studies have been focused on various object selection techniques in smooth pursuit-based gaze interaction; however, challenges in spatial accuracy and implementation complexity have not been resolved yet. To address these problems, we then proposed an approach using difference patterns between gaze and dynamic objects' trajectories for object selection named Difference Gaze Pattern method (DGP). Based on the experimental results, our proposed method yielded the best object selection accuracy of and success time of ms. The experimental results also showed the robustness of object selection using difference patterns to spatial accuracy and it was relatively simpler to be implemented. The results also suggested that our proposed method can contribute to spontaneous gaze interaction.

Abstract

High energy consumption in classrooms is a significant concern, often resulting from inefficient lighting and air conditioning systems. Specifically, the problem lies in the lack of automated control mechanisms that adjust energy use based on real-time occupancy data. This study aims to develop and evaluate a system that employs a camera integrated with the YOLOv8 algorithm to detect human presence and optimize energy usage by controlling lights and air conditioning. The system's performance was assessed in three different classroom environments: two large and one small. The system's accuracy for occupancy detection varied from 13.64% to 100%, depending on lighting conditions and room size. Light control accuracy was highest in the classrooms with consistent lighting, reaching 99.77%. Air conditioning control achieved perfect accuracy of 100% in the classroom with a SHARP brand AC, with a maximum remote-control range of 7 meters. These findings indicate that the system's performance is influenced by lighting conditions and room size, with smaller rooms showing better results. The system demonstrates promising potential for reducing energy consumption in classroom settings, thereby contributing to more sustainable energy practices.

Abstract

Various studies on educational approaches explore the solution to fill the gap between education and society's demands. Specifically in the engineering field, addressing this gap is particularly urgent because previous research indicated that engineering graduates experienced this problem more frequently. On the other hand, our community needs them since engineering is the driver of innovation and community change. Community-based projects, combining community-based research and project-based learning approaches, are potential approaches to meet this purpose, although more research is needed. This study aims to explore students' experiences while involved in community-based projects, including the processes, experiences, feelings, and values obtained during the project. This study used a qualitative approach using an open-ended questionnaire and interviews with 39 engineering students. The results of the study show three main stages in a community-based project in the field of engineering and positive results in terms of cognitive, affective, skills, and values. The dynamics of the process and the potential for community-based project development are provided in the discussion and conclusion section.
