In the video, I showed the operation of my prototype in detail. The learning cycle of each round is 40min (currently this is the result of my investigation, 40min is the most suitable time period for people to learn). At the end of the learning time, the user will get a ringtone sound reminder, and the distance sensor from this When you start working, if the user still monitors the range (that is, the distance from the desk is less than 40cm) during the rest period after the end of the learning time, the LED indicator light will light up, and the user will be prompted to leave the desk with a prompt tone . At this time, the user needs to play a balance fan palace game through the control balance board. The user needs to maintain a specific posture and balance the fan palace game by controlling the balance of the balance board. The rest time I set is 10min. When the rest time ends, the user needs to return to the desk to study. When the break time ends, if the distance detector cannot detect that the user is in front of the desk, the LED indicator light will be on and accompanied by a sound reminder. If the user returns to the desk, the LED light will go out and the prompt ringtone will also disappear.
