Display Screen Pattern Positioning for Cooperative Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing device positioning methods in cooperative systems require user operations or costly vibration apparatuses, complicating processes and increasing costs.
Innovation Solution
A method and apparatus that divide a display screen into regions, display patterns, and adjust them based on pattern information from a cooperative device to determine its position without user intervention or additional hardware, using only the display screen and camera.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a user operation is required for positioning the device, then the positioning can be achieved, but the process becomes complicated
Solution Approach 1:
The system enables automatic positioning through pattern recognition and coordinate transformation algorithms. The electronic device autonomously determines its position by capturing images of the display screen, processing the pattern information, and calculating coordinates without requiring any user operation or interaction.
Solution Approach 2:
The patent replaces manual mechanical positioning operations with an automated optical and computational system. Instead of requiring users to manually indicate position, the system uses image capture, pattern recognition, and coordinate transformation to automatically determine device position.
2Measurement precision
If a vibration apparatus is mounted on the mobile phone for positioning, then the positioning can be achieved, but the process becomes complicated and cost increases
Solution Approach 1:
The patent extracts the positioning function from hardware additions and relocates it to the software and display system. Instead of mounting vibration apparatus on the mobile phone, the positioning capability is achieved through the existing display screen showing patterns and the electronic device's image processing capabilities.
Solution Approach 2:
The display screen serves multiple functions: it displays content and simultaneously serves as a positioning reference by showing recognizable patterns. The camera captures both the display patterns and the mobile phone position, enabling the existing hardware to perform dual functions without additional components.
3Measurement precision
If a vibration apparatus is mounted on the mobile phone for positioning, then the positioning can be achieved, but the cost increases
Solution Approach 1:
The patent uses software-based patterns displayed on the screen instead of expensive physical vibration apparatus. The positioning information is conveyed through visual patterns that can be generated and modified software, which is significantly cheaper than hardware vibration motors and their associated mounting and calibration infrastructure.

AI summary
A method, apparatus and electronic device for positioning a device based on a device cooperative system are disclosed. A display screen of a first electronic device is divided into M regions on which N kinds of patterns are displayed; a first cooperative device acquires a pattern of a region where the first cooperative device locates and transmits pattern information to the first electronic device; after receiving the pattern information, the first electronic device judges whether a preset positioning condition is met, and if it is not, adjusts the regions in the display screen to make the first cooperative device continue to acquire the pattern of the region where the first cooperative device locates until the preset positioning condition is met; after the preset positioning condition is met, the first electronic device determines the position where the first cooperative device locates based on the pattern information.
