IoT Play Record Display Using Proximity Thresholds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In smart home scenarios, IoT devices like smart speakers and smart televisions cannot accurately distinguish between music play requests initiated by the account owner and those initiated by other family members, leading to reduced accuracy in content recommendations and poor user experience.
Innovation Solution
A play record display method that uses a server to determine whether the distance between a personal device and an IoT device is within a preset threshold, allowing accurate identification of play data ownership and improving content recommendation accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the server cannot distinguish between play requests from different users, then the system is simple to operate, but the content recommendation accuracy deteriorates
Solution Approach 1:
The patent introduces a personal device as an intermediary between the user and the IoT device. The personal device obtains location information and sends it to the server, which uses this location data to determine whether the IoT device is within a preset threshold distance of the personal device. This intermediary mechanism enables the server to distinguish between different users' play requests without requiring complex authentication protocols, thereby improving content recommendation accuracy while maintaining operational simplicity.
2Measurement precision
If the system includes location information to identify user preferences, then content recommendation accuracy is improved, but the device complexity increases
Solution Approach 1:
The patent extracts location information from the complex web of device interactions and uses it as a key distinguishing factor. By obtaining location information from the personal device and using it to determine spatial proximity, the system can accurately identify user preferences without needing to analyze complex usage patterns or authentication data. This extraction of a single critical parameter simplifies the overall system structure while improving recommendation accuracy.
3Measurement precision
If the system displays all play records without distance filtering, then the historical play record is complete, but the recommendation accuracy for the current user deteriorates
Solution Approach 1:
The patent applies local quality by filtering play records based on the spatial proximity condition. Instead of treating all play records uniformly, the system selectively includes only those play records where the IoT device was within a preset threshold distance of the personal device. This creates a localized subset of relevant play records that accurately reflects the current user's preferences, while excluding records from other family members regardless of their usage history.
Data Source
AI summary
An IoT device and a personal device of a user are bound to a same account. After receiving a request of playing multimedia data from the user, the IoT device may obtain, from a server, a multimedia data resource that the user requests to play. The server may determine whether a distance between the personal device and the IoT device is less than or equal to a preset distance threshold. If the distance between the personal device and the IoT device is less than or equal to the preset distance threshold, the server calculates, based on a pre-stored historical play data record of the bound account, a preference degree of the user for the multimedia data that the user requests to play.
