Remote Control Positioning for Personalized Content Recommendations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audiovisual content recommendation systems cannot distinguish between different users in close proximity, as GPS coordinates lack the necessary resolution to differentiate between positions within a room, leading to inadequate personalized content recommendations.
Innovation Solution
A content receiving device that uses position information from a remote control device, including distance, direction, and coordinates, to identify the user and modify the audiovisual program output, such as volume and brightness, and recommend content based on viewing habits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If GPS coordinates are used to determine device position, then broad location information can be obtained, but the resolution is insufficient to distinguish between different positions within a room
Solution Approach 1:
The patent transitions from two-dimensional GPS coordinates to three-dimensional spatial positioning by incorporating distance measurements from multiple remote control interfaces. This dimensional enhancement enables precise differentiation between devices in close proximity within the same room by adding depth information through triangulation methods.
Solution Approach 2:
The patent introduces signal strength measurements as an intermediary parameter to bridge the gap between GPS coordinates and precise device positioning. By using the remote control signal strength as a mediator, the system can infer distance and improve position resolution without directly implementing complex positioning hardware.
2Measurement precision
If multiple remote control interfaces are used to obtain direction and coordinates, then position accuracy improves, but device complexity increases
Solution Approach 1:
The patent makes the remote control interfaces multi-functional by using them not only for receiving control commands but also for determining device position and direction. This universal usage of existing interfaces reduces the need for additional positioning hardware, thereby improving measurement precision without proportionally increasing device complexity.
Solution Approach 2:
The patent combines the positioning function with the existing remote control signal reception function. By merging position determination with the already-present remote control interfaces, the system achieves accurate spatial awareness without adding separate positioning components, thus balancing precision and complexity.
3Adaptability or versatility
If position information is used to identify users and recommend content, then personalization improves, but information processing complexity increases
Solution Approach 1:
The patent implements a self-service approach where the system automatically determines device position, identifies the user based on position, and selects appropriate content without requiring manual user input. This automation improves personalization while managing processing complexity by integrating these functions into the existing content delivery workflow.
Solution Approach 2:
The patent establishes a feedback loop where device position information continuously informs content selection and presentation adjustments. By using real-time position data to dynamically adapt content recommendations and display parameters, the system achieves high adaptability while keeping processing manageable through event-driven updates rather than continuous analysis.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables personalized audiovisual content recommendations by accurately identifying users based on their positions and viewing habits, enhancing user experience by providing content of interest.
Implementation Method 1
The content receiving device obtains the distance between the remote control device and the content receiving device based on a power level, a time, or a phase of the signal when it is received by the remote control interface
Implementation Method 2
the content receiving device may modify the volume and/or brightness level of the audiovisual program based on the distance between the remote control device and the content receiving device
Implementation Method 3
The content receiving device may obtain viewing habit information for the identified user. The content receiving device may use the viewing habit information to select one or more audiovisual programs
Data Source
AI summary
A method for recommending audiovisual content includes receiving a signal transmitted by a remote control device at a content receiving device. Position information of the remote control device is obtained based on the signal transmitted by the remote control device. The position information can include a distance between the remote control device and the content receiving device, a direction of the remote control device with respect to the content receiving device, and coordinates of the remote control device. Viewing habits are obtained based on the position information of the remote control device. An audiovisual program is selected based on the viewing habits. The audiovisual program is recommended to a user by outputting data indicating the selected audiovisual program from the content receiving device.
