Display Apparatus Selection via Distance Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Selecting a television to control from multiple connected devices is cumbersome for users, as they must display and check information for each device, making it inconvenient to choose the desired one using a mobile device.
Innovation Solution
A method that detects the distance of multiple display apparatuses, selects the nearest one, and transmits information about it to another video apparatus, allowing for automatic or manual selection and content reproduction across devices without additional user input.

Engineering Contradiction Analysis
1Ease of operation
If a user manually selects a television from a list of multiple connected devices, then the user can choose the desired television, but the selection process becomes complicated and inconvenient
Solution Approach 1:
The system automatically determines which television to control by detecting the mobile device's location and identifying the nearest television, eliminating the need for manual selection. The television selection process serves itself by using spatial information and automatic identification algorithms.
Solution Approach 2:
The system pre-processes the television selection by automatically identifying and selecting the nearest television before the user needs to control it. This preliminary automatic selection spares the user from having to manually browse and select from a list of televisions.
2Ease of operation
If the system automatically selects the nearest display apparatus, then the selection process is simplified, but additional distance detection functionality is required
Solution Approach 1:
The mobile device's existing location detection capabilities (GPS, compass, accelerometer) are repurposed for television selection. These multi-functional components serve both navigation purposes and automatic television identification, avoiding the need for dedicated distance detection hardware.
Solution Approach 2:
The system uses the mobile device's location information as an intermediary to determine which television is nearest. Instead of directly measuring distance between the mobile device and televisions, the system uses the mobile device's known location and orientation to calculate which television is closest.
