Home Network Device Selection via Spatial Pointing Direction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in selecting the correct home network device for media sharing due to complex device models and numerous devices in a home network, leading to a degraded user experience.
Innovation Solution
A device selection method that utilizes a control device's pointing direction and/or deflection angle to determine the correct home network device, narrowing down the selection by defining a regional range or calculating included angles to identify the closest matching device, thereby simplifying the selection process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If all home network device models are displayed for user selection, then the user can choose from complete device list, but the selection complexity increases and user experience degrades
Solution Approach 1:
The patent segments the device selection process into two stages: first filtering devices by spatial location (pointing direction and deflection angle), then presenting only the relevant subset for user selection. This divides the overwhelming complete list into a manageable segment based on spatial context.
Solution Approach 2:
The patent applies local quality by making the device list dynamic and context-specific. Instead of showing all devices uniformly, it shows only those devices located within the pointing direction and deflection angle range, making the information quality adapted to the user's current spatial context.
2Measurement precision
If device models use private vendor naming rules, then each device can have unique identification, but user recognition and distinction become difficult
Solution Approach 1:
The patent introduces spatial parameters (pointing direction and deflection angle) as an intermediary between the user and device identification. Instead of directly presenting confusing device models, the system uses spatial context as a mediator to filter and present only relevant devices, making identification easier.
Solution Approach 2:
The patent changes the selection parameters from device model strings to spatial parameters (pointing direction and deflection angle). By changing what parameter the user interacts with, the system maintains precise device identification while making the interaction much more intuitive and easier to perform.

AI summary
A device selection method and apparatus is disclosed, where the method includes: responding, by a control device, to a selection operation of a user, and determining a pointing direction of the control device and/or a deflection angle of the control device according to sensing data collected by a sensor of the control device; and determining, according to the pointing direction of the control device and/or the deflection angle of the control device, a home network device selected by the user, so that a correctness rate of home network device selection is increased effectively.
