As part of the Christmas town under the auditorium on December 14, 2022, where craftsmen and artists from among students, employees and graduates of the university presented their products and works of art made from natural materials throughout the afternoon, feedback from students was collected through a creative idea via a QR code displayed on a kiosk with an aromatization function. This communicated the benefits of participating in the survey via a QR code, with each survey participant receiving a voucher for coffee in the university cafeteria under the auditorium as a thank you for their willingness and time. Feedback was submitted by 10 students????
