Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic device control systems cannot identify user information, leading to difficulties in automatically controlling device functions based on identification results, which can result in an unfavorable user experience.
Innovation Solution
An electronic device equipped with a camera assembly to capture depth images of users, allowing the controller to determine spatial positions and relative displacements, and subsequently control function assemblies such as playing and display assemblies to execute actions accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operation of volume adjustment button is used, then user can control volume, but user cannot operate button anytime especially when away from the device
Solution Approach 1:
The patent replaces the mechanical button operation with an optical sensing system. The camera assembly captures depth images to detect user position and movement, and the controller automatically adjusts volume based on this visual information, eliminating the need for manual button pressing.
Solution Approach 2:
The system enables automatic volume adjustment through self-service by detecting user presence and movement autonomously. The camera and controller work together to monitor user position and automatically modify volume without requiring user intervention, making the device adapt to user needs independently.
2Adaptability or versatility
If constant volume is maintained, then device operation is simple, but user experience deteriorates when user moves closer or farther from the device
Solution Approach 1:
The patent implements dynamic volume adjustment by continuously monitoring user position through depth image capture and comparing spatial positions across frames. The volume level changes dynamically based on detected user movement, allowing the system to adapt to varying user distances while maintaining smooth and natural audio experience.
Solution Approach 2:
The system employs feedback mechanisms by continuously capturing depth images, analyzing user position changes, and adjusting volume accordingly. The controller receives feedback from the camera assembly about user movement and automatically modifies volume to compensate for distance changes, creating a closed-loop control system that enhances user experience.

AI summary
An electronic device includes a camera assembly, a function assembly, and a controller. The camera assembly is configured to capture a first depth image of a first user and a second depth image of the first user. The controller is configured to determine a first spatial position between the first user and the camera assembly according to the first depth image, and control the function assembly to execute a first action according to the first spatial position. The controller further configured to determine a relative displacement between the first user and the camera assembly according to the first depth image and the second depth image, and control the function assembly to execute a second action according to the relative displacement. The second action is an action to adjust a result of the function assembly based on the first action. A method and a non-transitory storage medium are also provided.
