Mobile Device Positioning via Sensor Fusion and Visual Group Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In crowded or unfamiliar environments, it is difficult for individuals to locate each other within a group without frequent phone calls or messages, despite the widespread use of mobile devices for communication.
Innovation Solution
A mobile device equipped with a display, sensor unit, and transceiver unit, which calculates and displays the positions of both itself and other connected devices using internal and external positioning data, allowing users to easily locate each other through a positioning method that includes pairing, data exchange, and visualization of relative positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If phone calls or messages are used to confirm positions, then group members can locate each other, but it becomes inconvenient and requires frequent communication interruptions
Solution Approach 1:
The patent introduces a positioning system as an intermediary that automatically tracks and displays group member positions without requiring direct communication between members. The system mediates the location information exchange, allowing users to locate each other through automated position display rather than manual phone calls or messages.
Solution Approach 2:
The positioning system enables group members to automatically locate each other without manual intervention. The devices continuously exchange positioning data and update displays autonomously, making the location service self-operating and eliminating the need for users to actively initiate phone calls or send messages to confirm positions.
2Reliability
If no positioning system is used, then the mobile device functions are simple, but group members cannot easily locate each other in crowded environments
Solution Approach 1:
The patent integrates positioning functionality into existing mobile devices that users already carry. The system uses universal components like sensors, processors, and displays that are standard in modern mobile devices, allowing the positioning feature to be added without requiring specialized or complex dedicated equipment.
Solution Approach 2:
The positioning system merges multiple functions into a unified solution: sensor data acquisition, position calculation, data exchange, and visual display are combined into an integrated system within each mobile device. This consolidation reduces overall system complexity compared to using separate dedicated positioning devices for each function.
Data Source
AI summary
A mobile device, a positioning method and a computer-readable recording medium are provided. The mobile device includes a display, a sensor unit, a transceiver unit, and a processor. The sensor unit provides internal sensor data. The transceiver unit receives at least one external positioning data. The processor calculates a position of the mobile device based on the internal sensor data. The processor obtains a position corresponding to each of the external positioning data based on each of the external positioning data and controls the display to display multiple representative objects. Each of the representative objects is corresponding to one of the positions of the mobile device or the at least one external positioning data.
