Optimizing a display interface design for rollers is the focus of this study, in which the effects of cognitive load of the operator are taken into consideration, which greatly contribute to acquiring interface information accurately and enhancing cognitive efficiency. To reduce the cognitive demand of the operator, a commonly used generic display interface is modified in this study. Three methods are used to measure the cognitive load, including subjective (NASA Task Load Index) and physiological (eye movement) measurements and through task performance. These three measurements are used with two groups of subjects: those who view the original and those who are given the modified version during four given tasks. The findings show that the modified interface has a significant impact on eye movement and completion time of the four tasks. After a comprehensive analysis of the results from the three types of measurement, it is found that the modified interface is less cognitively demanding than the original interface and allows a higher cognitive performance, which accordingly demonstrates that the modifications made are effective in reducing cognitive load. This study therefore provides the scientific basis for advancing interface designs and evaluating the display interface designs for engineering equipment.

“…En los medios de transporte también están presentes los LEDs, un ejemplo muy común, son los indicadores de destino equipados en la parte delantera de los autobuses permitiendo a los peatones identificar rápidamente los números de los mismos [3], con el objetivo de mejorar la legibilidad y la visualización óptima de la información que se desplaza a lo largo del display. Otro sistema que pone a prueba la versatilidad de esta tecnología, es la transmisión de códigos de identificación a través de un canal VLC (Visible Light Communication, Canal de Comunicación de Luz), que en conjunto con otras tecnologías, se determinan las posiciones de los vehículos en función de la relación geométrica entre las coordenadas de los LEDs en las imágenes y sus coordenadas del mundo real, que se obtienen a través de los códigos de identificación [4].…”

This work proposes an electronic system which, adapted to a LED lamp, optimizes the use of electrical energy, improves lighting comfort, etc. All this is possible with the programming of an Ultrasonic Distance Sensor (#28015) through an Arduino Nano Rev. 3. This Arduino, connected to actuators, regulates the intensity of the light depending on the distance between the lamp and the work area. In case an object or a human being approaches or moves away from the lamp, the luminous intensity will increase or decrease in relation to the previously established parameters. In order to achieve this objective, the installation of a breadboard of the proposed system is carried out for its subsequent testing and simulation. Several open source software are also used, such as: Arduino, Fritzing, Inkspace, etc. The Arduino is used to program the brain of the operation, that is, the microcontroller in the arduino platform; Fritzing for the digital assembly in breadboard, its schematic and the PCB (Print Circuit Board), all this of the proposed circuit; and Inkspace for the creation of the components that are not available in the Fritzing. This project combines three technologies, which combined, result in a Distance & Light Intensity Smart Lamp.
