This study presents the development and implementation of a user-device interface using a resistive touch screen, enabling users to operate a Photobiomodulation (PBM) device developed at the Laboratory of Instrumentation and Biomedical Engineering effectively and efficiently, reducing the possibility of human errors caused by the equipment's interface. Using the DWIN® Resistive LCD DMG 80480C070 – 04 WTR module in conjunction with DWIN® DGUS software and designing five customized screens in CorelDRAW®, five control interfaces for the PBM equipment were developed. These interfaces were integrated into the DOIT ESP32 microcontroller, allowing precise control of the device's laser and LED clusters. The chosen display offers high resolution and durability, essential for the medical environment. The developed interfaces allow users to set parameters such as application time and energy of the PBM clusters simply and effectively. Applying these interfaces in the PBM equipment enables more direct and reliable interaction, following ABNT's technical standards and specifications. It is expected that the developed control interfaces will improve the usability of the medical equipment, reducing operational complexity and minimizing potential human errors caused by interfaces with poor usability, contributing to the advancement of biomedicine and highlighting the importance of graphic control interfaces in improving user-device interaction.

摘要

This study presents the development and implementation of a user-device interface using a resistive touch screen, enabling users to operate a Photobiomodulation (PBM) device developed at the Laboratory of Instrumentation and Biomedical Engineering effectively and efficiently, reducing the possibility of human errors caused by the equipment's interface. Using the DWIN® Resistive LCD DMG 80480C070 – 04 WTR module in conjunction with DWIN® DGUS software and designing five customized screens in CorelDRAW®, five control interfaces for the PBM equipment were developed. These interfaces were integrated into the DOIT ESP32 microcontroller, allowing precise control of the device's laser and LED clusters. The chosen display offers high resolution and durability, essential for the medical environment. The developed interfaces allow users to set parameters such as application time and energy of the PBM clusters simply and effectively. Applying these interfaces in the PBM equipment enables more direct and reliable interaction, following ABNT's technical standards and specifications. It is expected that the developed control interfaces will improve the usability of the medical equipment, reducing operational complexity and minimizing potential human errors caused by interfaces with poor usability, contributing to the advancement of biomedicine and highlighting the importance of graphic control interfaces in improving user-device interaction.
