Mobile Device Search for TV Content Without Screen Disturbance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing search function on smart TVs is limited when multiple people are viewing, as it can disturb others and is not user-friendly for searching objects displayed on the screen, especially when users are unfamiliar with keywords.
Innovation Solution
A method using a mobile device to receive information from an external image device, acquire search results, and display them without disturbing TV viewers, by incorporating timing information, images, objects, and metadata, allowing users to search objects on the TV screen efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a search function is implemented on a smart TV, then users can search information on objects displayed on the screen, but other viewers are disturbed while viewing TV
Solution Approach 1:
The patent introduces a mobile device as an intermediary between the user and the TV system. The mobile device receives content information from the TV, performs search operations, and returns results to the user. This mediator allows the user to search without directly interacting with the TV, thus avoiding disturbance to other viewers while maintaining search functionality.
2Ease of operation
If users directly enter keywords to search objects on TV screen, then search functionality is available, but it becomes difficult when users are not familiar with keywords
Solution Approach 1:
The system automatically captures content information (images, metadata, objects) from the TV screen without requiring user input of keywords. The mobile device receives this information and performs automated object recognition and search, enabling users to search simply by pointing the mobile device at the screen rather than typing complex keywords.
3Loss of information
If search results are displayed on the TV screen, then all viewers can see the search results, but it interrupts the TV viewing experience for everyone
Solution Approach 1:
The search results are displayed locally on the individual user's mobile device rather than on the shared TV screen. This allows each user to view their own search results privately on their personal device without affecting the TV viewing experience for other viewers in the room.
