Mobile Terminal Close-Range Object Query Randomization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing short-distance object search function in mobile terminals often displays repetitive results when searching for objects in the same location, leading to poor effectiveness due to the repeated display of uninteresting objects.
Innovation Solution
A method and apparatus that receive a short-distance object search request, determine objects within preset distance ranges, and randomly select and present objects from these ranges, ensuring randomness and reducing duplication by accumulating differences in object quantities across ranges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If objects are selected based on distance order for presentation, then the relevance and importance of close objects are improved, but the diversity and novelty of search results deteriorate due to repeated display of same objects
Solution Approach 1:
The patent applies dynamics by making the search result selection process adaptive rather than static. It introduces a dynamic adjustment mechanism that modifies the quantity of objects selected from each distance range based on historical search data. The system dynamically changes the selection strategy: when a user searches multiple times in the same location, the system reduces the quantity of objects from previously searched distance ranges and increases the quantity from other distance ranges, thereby providing diverse results while maintaining distance-based relevance.
2Stability of the object's composition
If the same distance-based selection strategy is used for multiple searches, then the consistency of search logic is improved, but the effectiveness of search function deteriorates due to repetitive results
Solution Approach 1:
The patent implements feedback by using historical search data to inform future search result selection. The system records the quantity of objects selected from each distance range in previous searches and uses this feedback to adjust the selection for current searches. When a user performs multiple searches in the same location, the system references historical data to modify the selection strategy, reducing repetition and improving effectiveness while maintaining logical consistency through a structured adjustment mechanism.
Solution Approach 2:
The patent applies parameter changes by modifying the selection parameters (quantity of objects from each distance range) based on search history. Instead of using fixed selection parameters, the system dynamically adjusts these parameters according to historical data. The adjustment involves changing the quantity parameter for each distance range: reducing it for ranges that have been heavily searched and increasing it for ranges that have been under-sampled, thereby improving search effectiveness while maintaining consistency in the adjustment logic.

AI summary
Disclosed are a method and device for querying close-range objects, belonging to the technical field of mobile terminals. The method comprises: receiving a close-range object query request sent by a target terminal, and acquiring location information of the target terminal; separately determining, according to the location information of the target terminal, object location information that is stored in advance and is used for querying a close-range object, and a plurality of preset distance ranges, objects having distances from the target terminal within all the distance ranges so as to obtain objects corresponding to all the distance ranges; and separately selecting objects to be shown randomly from the objects corresponding to all the distance ranges, and showing to the target terminal the objects to be shown. The present disclosure can enhance the effectiveness of a close-range object query function.
