Inappropriate use of cell phones can affect the normal order of the lecture, and reasonable control of cell phone use in the classroom can improve students' learning efficiency. This project designs a cell phone smart organizer with a circumferential distribution structure. It uses a special crank slider mechanism to make the cell phone in the organizer only perform the circumferential translational movement, preventing collision damage to the cell phone. Arduino is used for control, and the

... vo drives the crank rotation. Based on the OpenMV module, the cell phone can be accessed through face recognition, which enhances the security and operability of the organizer. At the same time, with the LCD, the face recognition result is dynamically displayed, which is convenient for human-computer interaction.
