Rotatable Smart Speaker Display for Multi-User Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional smart audio equipment lacks the ability to perform directional display effectively during multi-person interactive use, limiting the visual experience for multiple users.
Innovation Solution
The implementation of a directional display method and device that utilizes a camera module and a rotatable display screen to detect user positions and adjust the display direction, ensuring all users are within the display area by calculating and adjusting the compensation angle to zero in half screen display mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display screen tracks a single user in conventional audio equipment, then the display direction can be adjusted for one user, but the equipment cannot support multi-person interactive use effectively
Solution Approach 1:
The display screen transitions from static single-user tracking to dynamic multi-user adaptation. The system continuously detects user positions via camera module and automatically adjusts the display direction in real-time based on the detected positions, enabling seamless multi-person interaction without manual intervention.
Solution Approach 2:
The patent introduces a new dimension of operation by implementing half-screen display mode that divides the display area. This allows the screen to simultaneously serve multiple users by displaying different content in different regions, effectively solving the multi-person interaction problem without requiring complex mechanical rotation for every user.
2Adaptability or versatility
If the display screen is fixed in one direction, then the device structure is simple, but multiple users cannot all be within the display area simultaneously
Solution Approach 1:
The display screen is made rotatable to dynamically adjust its orientation based on detected user positions. This dynamic capability allows the single display screen to cover multiple user positions sequentially, achieving multi-user support without requiring multiple fixed screens.
Solution Approach 2:
The patent adds the temporal dimension to display orientation by implementing automatic rotation based on user detection. Instead of having multiple fixed screens for different directions, the system rotates the single screen to face different users at different times, reducing hardware complexity while maintaining multi-user capability.

AI summary
A directional display method and device of audio equipment, and audio equipment are disclosed. The audio equipment comprises a camera module and a display screen that is circumferentially located on sides of the audio equipment. The display screen is rotatable relative to the audio equipment. The method comprises activating the camera module for panoramic shooting to detect a user position in response to an activation signal acquired; determining whether the display screen is in half screen display mode according to a relationship between the user position and a center position of the audio equipment; and when it is determined that the display screen is in half screen display mode, determining a compensation angle of a display direction of a half screen display area relative to the user position, and adjusting the display direction of the half screen display area so that the compensation angle is zero.
