In the disabled group, the blind group occupies a large part. The continuous development of science and technology promotes the diversity of society. As a member of the society, the blind also have the right to leave home and pursue a better, more comfortable and healthy lifestyle. How to promote the blind to travel safely through the assistance of the blind rod is the common pursuit of the blind community. The development of technology provides power for the intelligent and interactive development of blind rod product design in the future. Intelligent blind rod product design based on user experience has become a problem we urgently want to solve. This product is in the form of a bracelet to meet the needs of the blind to accurately perceive obstacles. Through the positioning system, the bracelet automatically locates the current position. Through RFID technology, automatic identification of obstacles. The bracelet adjusts the vibration amplitude and detection range by means of buttons. Clockwise rotation means amplitude increase, counterclockwise and vice versa. Turn the button clockwise, the range of detection of the bracelet is larger, vice versa. The detection radius of the bracelet is greater than or equal to 0.5 meters and less than or equal to 100 meters. Turn the button once for 0.5 meters. Through automatic adjustment, blind people can adjust the detection range they need by themselves in any action.
