After the desk is arranged on the desk, the use area of the desk can be occupied. The larger volume and the bright color also affect the learning attention of the surrounding students. Because the children have low consciousness of correcting sitting postures and can obtain expected effects only through forced training, the sitting posture corrector is more suitable for family use of the children. Some of the products are provided with an acousto-optic alarm auxiliary function, but the fundamental defects of the products cannot be eliminated.

The electronic distance measurement type sitting posture corrector adopts an ultrasonic or infrared technology to detect the distance from the face of a user to the desktop, and gives an alarm prompt when the distance exceeds a set distance range, so that the aim of correcting the sitting posture is fulfilled. Such an appliance needs to be placed/worn in a conspicuous position in order to measure the distance from the user's face to the book. When the audible and visual alarm gives an alarm to a user, the learning attention of surrounding students can be influenced. In addition, the safety and environmental protection of the ultrasonic and infrared radiation exposure are further discussed.
