An interactive method and system based on ultrasonic positioning

Abstract

The invention discloses an interactive method and system based on ultrasonic positioning. Together with at least two terminals to form a positioning unit, and participate in the implementation of relative positioning within the positioning unit; relative positioning includes: each terminal in the positioning unit sends an ultrasonic positioning signal with its own identification, and receives signals sent by other terminals in the positioning unit Ultrasonic positioning signals with their own identification; determine the distance information between any two terminals based on the ultrasonic positioning signals between any two terminals; determine the relative distance between each terminal based on the distance information between two terminals in the positioning unit Position information, and share relative position information in the positioning unit; analyze the identification of other terminals from the ultrasonic positioning signals sent by other terminals, and display the relative position information of other terminals and the identification of other terminals in association, and share the identification of other terminals Sent to the network side to retrieve associated information corresponding to the identifiers of other terminals; display associated information.

Description

technical field [0001] The present invention relates to the technical field of electronic applications, in particular, to an interaction method and system based on ultrasonic positioning. Background technique [0002] In 1959, American scholar B. Shackel first proposed the concept of human-computer interaction engineering. Since the late 1990s, with the rapid development and popularization of high-speed processing chips, multimedia technology and Internet technology, research on human-computer interaction has focused on intelligent interaction, multi-modal (multi-channel)-multimedia interaction, and virtual interaction. As well as human-computer collaborative interaction, that is, human-centered human-computer interaction technology. [0003] With the development of smart devices, their functions are becoming more and more powerful, and their application range is wider and wider. People's lives are inseparable from smart devices. Smart terminals such as mobile phones have ...

Problems solved by technology

The GPS positioning accuracy is high, but it is greatly affected by the signal, and the highest accuracy can reach about 10 meters. In addition, the GPS signal received by the device is very weak when the device is indoors, making it difficult to locate

In the precise positioning of small areas, the positioning methods of GPS and base stations are not suitable
