Distributed Scanning Frequency Allocation for AR/VR Location
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently managing distributed scanning across multiple devices, particularly in augmented reality (AR), virtual reality (VR), and mixed reality (MR) applications, due to factors like battery drain and increased latency.
Innovation Solution
A method where a first device in a set of devices distributes frequency range portions for scanning based on the state of each device, such as battery state, thermal state, or resource availability, to optimize scanning efficiency and reduce latency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If distributed scanning is implemented across multiple devices, then location determination accuracy is improved, but battery drain increases
Solution Approach 1:
The frequency range is divided into multiple portions, with each device scanning a specific portion. This segmentation allows the system to achieve comprehensive location determination across all devices while distributing the energy consumption burden, preventing any single device from draining its battery completely.
Solution Approach 2:
The system dynamically adjusts scanning parameters based on device state metrics (battery level, thermal state, available resources). Devices with lower battery levels or higher thermal states are assigned different scanning portions or reduced scanning intensity, optimizing the balance between location accuracy and energy consumption.
2Measurement precision
If distributed scanning is implemented across multiple devices, then location determination accuracy is improved, but latency increases
Solution Approach 1:
By dividing the frequency range into portions assigned to different devices, the system enables parallel scanning operations. Multiple devices can scan their assigned portions simultaneously, significantly reducing the total scanning time and latency compared to sequential scanning of the entire frequency range by a single device.
Solution Approach 2:
The system determines device states (battery level, thermal state, available resources) before distributing scanning portions. This preliminary assessment allows for optimized assignment that minimizes scanning latency while ensuring devices are in suitable states to handle the scanning tasks without causing system instability.
3Use of energy by moving object
If scanning is distributed based on device state, then battery drain is reduced, but device complexity increases
Solution Approach 1:
The system merges multiple functions into a centralized scanning management mechanism. The first device determines states of all devices in the set, distributes scanning portions, and collects scan data, thereby reducing the complexity burden on individual devices while achieving state-aware energy optimization.
