AR Positioning Feedback for Reliable Device-to-Device Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing device-to-device communication methods require precise positioning, leading to user errors due to incorrect device alignment, which can result in frustrating experiences, especially when multiple devices need to be commissioned in an area.
Innovation Solution
A mobile device provides real-time visual feedback by overlaying a positioning guide matching the target device's indicia, ensuring correct alignment for short-range communication, using camera imaging and augmented reality to guide the user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If precise positioning is required for device-to-device communication, then communication reliability is improved, but user operation difficulty increases due to incorrect device alignment
Solution Approach 1:
The patent implements real-time visual feedback by displaying a live camera feed with an overlay that shows the target device's indicia and a positioning guide. This feedback mechanism allows users to see their device's relative position to the target device and adjust alignment accordingly, resolving the contradiction between requiring precise positioning for reliable communication and making the operation easy for users.
Solution Approach 2:
The patent introduces an intermediary visual guide (the overlay showing the indicia and positioning guide) that mediates between the user and the alignment requirement. This intermediary element translates the abstract requirement of 'precise positioning' into a concrete visual target that users can easily align with, thereby maintaining communication reliability while simplifying user operation.
2Measurement precision
If real-time visual feedback with overlay is provided, then positioning accuracy is improved, but device complexity increases
Solution Approach 1:
The patent leverages existing multi-functional components already present in mobile devices - specifically the camera and display - to achieve real-time visual feedback with overlay. By making these existing components serve the additional function of positioning guidance, the patent improves positioning accuracy without significantly increasing device complexity, as no dedicated hardware was added.
Solution Approach 2:
The patent creates a visual copy of the target device's indicia on the display screen, overlaid with positioning guidance information. This copy allows users to interact with a simplified representation of the alignment requirement rather than directly manipulating the physical device, thereby achieving precise positioning guidance while keeping the system relatively simple.
