Description Dynamic lighting is playing a key role in education, by considering the main photometric variables such as the correlated color temperature and the illuminance to increase student’s attention levels inside the classroom. In the case of design students, the project component is fundamental for teaching, where students mainly need to develop activities such as presentation to listen to the teacher instructions, ideation and sketching to propose a solution according to the problem being addressed, and exhibition to present the work that has been done. These activities require specific and adequate lighting conditions to generate a positive impact on the performance of students. This article presents the design of a dynamic lighting system capable of adjusting the correlated color temperature in a range from 2500 K to 6500 K and the illuminance levels in a range from 0 lx to 800 lx to enhance the sustained and fixed attention of design students inside the classroom according to the type of activity that is being developed. The performance of the system was evaluated experimentally by measuring student’s attention inside the ergonomics and usability laboratory by using the Gesell chamber, the Emotiv Epoc EEG Headset with 14 electrodes to measure the brain activity and obtain engagement and focus levels, the eye tracking Tobii glasses, and a protocol to evaluate performance including several surveys and camera observation. In conclusion, the dynamic lighting system can improve the attention of design students by configuring the photometric variables according to the type of activity that is being done.
La iluminación dinámica puede generar un gran impacto en la educación, ya que tiene en cuenta las principales variables fotométricas tales como la temperatura de color y la iluminancia para aumentar la atención de los estudiantes dentro de un salón de clases. En el caso particular de los estudiantes de diseño, el desarrollo de proyectos es un componente fundamental para la enseñanza, en donde los estudiantes principalmente realizan actividades tales como presentar atención a una presentación, realizar ejercicios de ideación y bocetación, y exhibir sus propuestas. Estas actividades requieren de unas condiciones de iluminación específicas y adecuadas para generar un impacto positivo en el desempeño de los estudiantes. Este artículo presenta el diseño de un sistema de iluminación dinámica capaz de ajustar la temperatura de color en un rango entre los 2500 K hasta los 6500 K y los niveles de iluminancia en un rango entre 0 lx y 800 lx para incrementar la atención sostenida y selectiva de los estudiantes de diseño dentro de un salón de clases teniendo en cuenta el tipo de actividad que se está desarrollando. El desempeño del sistema fue evaluado experimentalmente midiendo la atención de los estudiantes dentro de un laboratorio de ergonomía y usabilidad utilizando una cámara de Gesell, una diadema Emotiv Epoc EEG de 14 canales para medir la actividad cerebral, unas gafas de seguimiento ocular y un protocolo para evaluar el desempeño utilizando encuestas y observación a través del uso de cámaras. En conclusión, el sistema de iluminación dinámica puede incrementar los niveles de atención selectiva y sostenida de los estudiantes de diseño al configurar la iluminación de manera específica dependiendo del tipo de actividad que se vaya a desarrollar.
